Acne scars can remain long after active breakouts have settled. For some people they are a few shallow marks visible only in certain light. For others they create deep depressions, uneven texture, raised areas or widespread changes across the face, chest or back.
The term “acne scar” is also used loosely. A flat red, purple or brown mark left after a spot is not necessarily a permanent scar. These colour changes can be very noticeable and may take months to fade, but they do not always represent structural damage to the skin.
True acne scars form when inflammation damages tissue and the skin heals with too little or too much collagen. The result may be a narrow ice-pick scar, a broader boxcar depression, an undulating rolling scar or a raised hypertrophic or keloid scar.
These distinctions matter because there is no single best acne-scar treatment. A laser may improve one scar while doing little for another. Microneedling can help selected texture changes but cannot release every tethered rolling scar. Strong peels may improve superficial damage yet create avoidable pigmentation when poorly chosen or performed.
The most effective plans are usually based on scar type, skin tone, active acne, medical history, downtime, budget and realistic expectations. Combination treatment is common because many people have more than one type of scar.
This guide explains how acne scars form, how to recognise the main types, which treatments may help, what private treatment can cost in the UK and how to reduce the risk of making scarring or pigmentation worse.
If you still have regular spots, nodules or cysts, controlling the acne should usually come before elective scar procedures. Our guide to acne treatment in the UK explains pharmacy products, prescription options, hormonal treatment, antibiotics and isotretinoin.
Important: This article provides general information rather than a diagnosis or personal treatment plan. Acne scars should be assessed by a suitably qualified practitioner before invasive treatment, especially if you have active acne, darker skin, a tendency to form keloids or a history of poor wound healing.
What causes acne scars?
Acne is an inflammatory condition involving hair follicles and sebaceous glands. When a follicle becomes blocked and inflamed, the surrounding skin may be damaged.
Superficial spots often heal without permanent textural change. Deeper nodules and cysts are more likely to injure tissue because inflammation extends further beneath the skin.
As the area heals, the body produces collagen. If too little supportive tissue is formed, the surface may sink and create an atrophic or indented scar. If too much collagen is produced, the scar may become raised.
Scarring risk is influenced by:
- the severity and depth of acne;
- how long inflammatory acne remains uncontrolled;
- genetic susceptibility;
- previous keloid or raised scarring;
- picking, squeezing or scratching spots;
- the location of the acne;
- delayed access to effective treatment; and
- individual healing and inflammatory responses.
Severe acne is not the only form that can scar. Repeatedly picking milder spots can also cause persistent marks and depressions.
Why squeezing spots increases the risk
Squeezing may rupture the follicle wall and push inflammation deeper into surrounding tissue. It can also introduce bacteria, prolong healing and increase the chance of post-inflammatory pigmentation.
A spot that appears ready to empty may still contain inflammation beneath the surface. Forceful extraction can create more damage than leaving it alone.
Preventing new scars
The most important step is controlling active acne early enough to prevent repeated deep inflammation. Moderate, severe, painful or scarring acne should not be managed indefinitely through changing skincare products.
A GP may prescribe combinations of topical treatments, oral antibiotics or hormonal treatment. Dermatology referral may be appropriate for severe acne, nodules, cysts, treatment-resistant disease, substantial psychological distress or a risk of permanent scarring.
Isotretinoin may be considered for severe acne that has not responded to suitable standard treatment or where there is a significant risk of permanent scarring. It requires specialist prescribing and careful discussion of its risks and monitoring requirements.
Acne scars versus red or brown acne marks
Before paying for scar treatment, it is important to establish whether the concern is a change in colour, texture or both.
Post-inflammatory erythema
Post-inflammatory erythema describes flat red, pink or purple marks that remain after inflamed acne has healed. They are particularly visible in lighter skin, although inflammation can create vascular colour changes in any skin tone.
These marks are not indented scars. They often fade gradually, but the process may take months. Sun protection, gentle skincare and controlling new acne can help prevent them from becoming more noticeable.
Persistent redness may sometimes be treated with vascular lasers or intense pulsed light, depending on the person’s skin type and the nature of the vessels. These procedures target colour rather than rebuilding an indented scar.
Post-inflammatory hyperpigmentation
Post-inflammatory hyperpigmentation creates flat brown, grey or darker patches after inflammation. It is especially common and persistent in darker skin tones.
Hyperpigmentation may improve with time, sun protection and treatments such as azelaic acid, retinoids or other pigment-directed medicines prescribed or recommended for the individual.
Aggressive peels, lasers or poorly controlled inflammation can make pigmentation worse. Treatment should therefore reduce irritation rather than create repeated cycles of injury.
Hypopigmentation
Some healed areas become lighter than the surrounding skin. This may reflect reduced pigment production or deeper damage.
Hypopigmentation can be more difficult to treat than excess pigment. Procedures that create additional inflammation should be approached cautiously.
True textural scarring
A true atrophic acne scar creates a depression, sharp edge or uneven surface because tissue support has been lost. Raised scars extend above the surrounding skin because too much collagen has formed.
Colour and texture often coexist. A person may have a rolling depression with brown pigmentation or an ice-pick scar surrounded by redness. Each component may need a different treatment.
The main types of acne scars
Atrophic scars are commonly divided into ice-pick, boxcar and rolling scars. Many people have a mixed pattern, so the categories are guides rather than perfect boundaries.
Ice-pick scars
Ice-pick scars are narrow, deep depressions that extend into the skin. They often look like enlarged pores or small punctures.
Because the opening is narrow and the tract is deep, treatments acting mainly across the surface may produce limited improvement. Ice-pick scars are often treated with focused techniques such as punch excision or TCA CROSS, depending on their number, depth and location.
Boxcar scars
Boxcar scars are round or oval depressions with more clearly defined edges. They can be shallow or deep and may resemble small chickenpox scars.
Shallow boxcar scars may respond to resurfacing, microneedling or fractional treatments. Deep boxcar scars may require punch elevation, excision, subcision or a combination approach.
Rolling scars
Rolling scars create broad, shallow depressions and an undulating surface. They are often caused by fibrous bands that tether the skin to deeper tissue.
Because the main problem is beneath the surface, resurfacing alone may not fully correct them. Subcision is commonly considered to release the tethering bands before or alongside other treatment.
Hypertrophic scars
Hypertrophic scars are raised but remain largely within the boundaries of the original inflamed area. They may be firm, itchy or uncomfortable.
They are more common after significant inflammation on areas such as the chest, shoulders and back.
Keloid scars
Keloids are raised scars that grow beyond the original area of injury. They may continue enlarging, become itchy or painful and recur after removal.
Keloids are more common in people with darker skin and those with a personal or family tendency to develop them. Cutting out a keloid without an appropriate recurrence-prevention plan may stimulate another, sometimes larger scar.
Macular scars
The term macular scar is sometimes used for flat colour changes after acne. These may be red, brown or lighter than the surrounding skin but do not necessarily involve loss or excess of tissue.
Calling every mark a scar can lead patients towards expensive resurfacing when the primary problem is pigmentation or redness.
How acne scars should be assessed
A useful assessment should examine more than the number of visible depressions.
The clinician should determine:
- whether acne is still active;
- which scar types are present;
- whether scars are shallow, deep or tethered;
- whether redness or pigmentation is contributing to their appearance;
- your skin tone and response to inflammation;
- whether you form raised or keloid scars;
- previous acne and scar treatments;
- medicines and relevant health conditions;
- how much downtime you can accept;
- your budget and treatment priorities; and
- whether your expectations are realistic.
Lighting changes how scars appear
Indented scars cast shadows, which is why they often look worse under strong overhead lighting or sunlight from the side. Consistent photography is useful when assessing treatment results.
Before-and-after photographs should use similar lighting, camera distance, facial expression and skin preparation. Makeup, different angles and soft frontal lighting can exaggerate apparent improvement.
The stretch test
A practitioner may gently stretch the skin to see whether an indentation becomes flatter. Rolling scars that improve when stretched may be tethered and potentially suitable for subcision.
Deep ice-pick and sharply edged boxcar scars are less likely to disappear through stretching.
Active acne should usually be treated first
Performing repeated scar procedures while new inflammatory lesions continue to appear can be frustrating and counterproductive. New scars may form while old ones are being treated, and active infection or inflammation may increase procedural risk.
There are exceptions where acne and scarring are addressed within one coordinated dermatology plan, but patients should be cautious of clinics that ignore active disease and move directly to cosmetic resurfacing.
Medical history matters
Tell the practitioner about:
- current and previous isotretinoin use;
- pregnancy or breastfeeding;
- cold sores;
- bleeding or clotting disorders;
- blood-thinning medicines;
- diabetes or immune suppression;
- eczema, psoriasis or vitiligo;
- previous pigmentation after treatment;
- keloid scars;
- recent tanning or sun exposure; and
- earlier laser, peel, filler or surgical treatment.
The historical rule that every procedure must be delayed for a fixed period after isotretinoin has become more nuanced. Timing should be decided according to the particular procedure, skin condition, dose, healing risk and current specialist advice rather than through a blanket assumption.
Treatments for ice-pick and deep boxcar scars
Deep, narrow scars are often the least responsive to treatments that act evenly across the entire skin surface. Focused treatment may produce more meaningful improvement while limiting injury to surrounding normal skin.
TCA CROSS
TCA CROSS stands for chemical reconstruction of skin scars. A high-strength trichloroacetic acid solution is placed carefully inside individual scars rather than across the whole face.
The controlled chemical injury encourages remodelling within the scar. It is most often considered for ice-pick scars and selected narrow boxcar scars.
Several sessions may be required. Temporary frosting, crusting, redness and pigment change can occur. Post-inflammatory hyperpigmentation is an important consideration in darker skin tones.
TCA CROSS should not be confused with an ordinary cosmetic facial peel. The acid is concentrated and must be applied precisely. Spillage beyond the scar can enlarge the injury or create a new mark.
Punch excision
Punch excision removes an individual deep scar using a small circular surgical instrument. The opening is then closed, usually leaving a small linear scar that may be less noticeable than the original depression.
This approach may be suitable for a limited number of deep ice-pick or boxcar scars. It is not practical for treating hundreds of shallow scars.
Risks include bleeding, infection, pigmentation, a visible replacement scar and poor wound healing.
Punch elevation
During punch elevation, the base of a boxcar scar is released and raised closer to the level of the surrounding skin rather than removed entirely.
Resurfacing may later be used to blend the edges after healing.
Punch grafting
A deep scar may occasionally be removed and replaced with a small skin graft, often taken from behind the ear. Differences in texture or colour can remain, so this is generally reserved for carefully selected scars.
Why laser alone may not be enough
Laser resurfacing can soften the edges and surface texture around some deep scars, but it may not reach or eliminate the full depth of an ice-pick tract.
A combined plan might use TCA CROSS or punch treatment first, followed by resurfacing once the scars have healed.
Treatments for rolling and tethered scars
Rolling scars often form because fibrous tissue pulls the skin down from beneath. Treating only the surface may polish the area without releasing the cause of the depression.
Subcision
Subcision is a minor surgical procedure in which a needle or specialised instrument is passed beneath the scar to release tethering bands.
The controlled injury and temporary space beneath the scar may also stimulate repair and collagen formation. Subcision is particularly associated with rolling scars, although selected boxcar scars may also benefit.
Swelling and bruising can be substantial, and small areas of bleeding beneath the skin are expected. Other risks include infection, haematoma, pigmentation, nerve or vessel injury, persistent lumps and an uneven result.
One session may help, but repeated treatment is sometimes required.
Subcision with filler
After a tethered scar has been released, a practitioner may use a small amount of dermal filler to support the depression and reduce immediate reattachment.
Filler is not suitable for every scar and adds its own risks, including swelling, nodules, infection and vascular occlusion. The practitioner should understand both scar surgery and injectable complications.
Our guide to dermal fillers in the UK explains filler types, serious warning signs and how to check a practitioner.
Subcision with platelet-rich plasma
Some clinics combine subcision with platelet-rich plasma, often shortened to PRP. A patient’s blood is processed to concentrate platelets before the resulting preparation is injected or applied.
PRP may support healing in some treatment plans, but marketing claims frequently go beyond the certainty of the evidence. It should not distract from selecting the correct structural treatment for the scar.
Acne-scar surgery
Where a scar is broad, sharply defined or resistant to less invasive treatment, a dermatologist or plastic surgeon may consider excision, elevation or another surgical revision.
Surgery replaces one scar with another. The goal is a flatter or less visible scar, not completely unmarked skin.
Microneedling and radiofrequency microneedling
Microneedling uses multiple fine needles to create controlled channels in the skin. The healing response encourages collagen remodelling over time.
It is commonly considered for shallow boxcar scars, rolling texture and general unevenness. It is less likely to correct deep ice-pick scars or strongly tethered depressions when used alone.
What treatment involves
A topical anaesthetic is usually applied before a medical microneedling session. The practitioner passes a pen or other needling device over the treatment area at a selected depth.
Redness, swelling, pinpoint bleeding and sensitivity are expected afterwards. The skin may feel similar to sunburn for a few days.
Improvement develops gradually as collagen remodels. A course of several sessions is commonly recommended rather than one treatment.
Radiofrequency microneedling
Radiofrequency microneedling delivers energy through needles beneath the skin. The combination of controlled needling and heat is intended to stimulate remodelling at selected depths.
Potential advantages include adjustable treatment depth and less surface injury than some ablative lasers. However, it can still cause burns, grid marks, prolonged redness, fat loss, pigmentation changes or scarring when settings and placement are inappropriate.
Microneedling and darker skin tones
Microneedling does not rely on targeting pigment in the way some lasers do, which can make it an option for a wider range of skin tones. This does not make it risk-free.
Excessive depth, inflammation, infection or poor aftercare can still cause post-inflammatory hyperpigmentation. The practitioner should have experience treating skin with a similar tone and pigment response.
Home dermarollers
Home rollers generally do not reproduce professional medical microneedling. Short needles may have limited effect on established scars, while longer or repeatedly reused devices can cause infection, irritation, pigmentation and track marks.
Do not needle over active inflammatory acne, cold sores, infected skin or an unexplained rash.
Laser resurfacing and other energy-based treatments
Laser treatment can improve acne-scar texture by creating controlled injury and stimulating remodelling. The best device and settings depend on scar type, skin tone, downtime and risk tolerance.
Ablative laser resurfacing
Ablative lasers, including carbon dioxide and erbium systems, remove or vaporise controlled areas of skin. Fractional ablative treatment creates microscopic treatment columns while leaving intervening skin intact to support healing.
These treatments can produce meaningful improvement in selected boxcar and rolling scars, but they involve downtime and important risks.
Possible effects include:
- pain and swelling;
- oozing and crusting;
- prolonged redness;
- infection;
- cold-sore reactivation;
- post-inflammatory hyperpigmentation;
- loss of pigment;
- visible treatment lines; and
- new scarring.
People with darker skin tones require especially careful assessment because heat and inflammation can trigger persistent pigmentation changes.
Non-ablative fractional lasers
Non-ablative lasers heat controlled areas beneath the surface without removing the full outer layer. Downtime is generally shorter than with ablative resurfacing, but several treatments may be needed and results may be more modest.
Vascular lasers and light treatments
Vascular lasers may reduce persistent red marks rather than indented scar depth. Intense pulsed light may also be considered for selected colour concerns, although it is technically not a laser.
A treatment that reduces redness can make scars appear less prominent even if the underlying depression remains.
Choosing a laser clinic
Ask:
- which exact device will be used;
- whether it is ablative or non-ablative;
- why it matches your scar type;
- how the settings are selected for your skin tone;
- whether a patch test is appropriate;
- what eye protection is used;
- who will manage burns or pigment changes;
- how much downtime is realistic; and
- whether the operator regularly treats acne scars rather than only hair removal.
Owning a laser does not mean a clinic can diagnose scars or use the device safely across every skin type.
Chemical peels, resurfacing and topical treatments
Chemical peels use controlled chemical injury to remove or remodel layers of skin. Their effect depends on the substance, concentration, application method and depth.
Superficial peels
Superficial peels may help active comedonal acne, mild pigmentation and surface roughness. They are unlikely to correct deep structural scars.
Common ingredients include glycolic, salicylic, mandelic or lactic acid. Even a superficial peel can cause irritation and pigmentation if used too aggressively.
Medium and deep peels
Stronger peels penetrate more deeply and can produce greater resurfacing, but they also involve longer healing and higher risks.
Possible complications include prolonged redness, infection, pigment loss, hyperpigmentation, heart-related toxicity with certain deep-peel agents and new scarring.
Deep peels are not routine salon treatments and require appropriately qualified medical oversight.
Dermabrasion and microdermabrasion
Dermabrasion mechanically resurfaces deeper layers of skin and may improve selected scars. It is a significant procedure with risks including bleeding, infection, pigmentation and scarring.
Microdermabrasion is much more superficial. It may temporarily improve smoothness but is unlikely to remodel established deep acne scars.
Prescription retinoids
Topical retinoids can treat active acne and may gradually improve fine surface texture and pigmentation. They do not release tethered scars or refill deep tissue loss.
Retinoids can cause irritation and increase sun sensitivity. Some are not suitable during pregnancy, so personal medical advice is important.
Silicone and scar gels
Silicone products are primarily used for raised scars rather than indented acne scars. They will not lift ice-pick, boxcar or rolling depressions.
Skincare products claiming to erase all acne scars should be viewed cautiously. Creams can support the skin barrier, reduce pigmentation and help prevent new acne, but they cannot reproduce the structural effects of surgery or resurfacing.
Treating raised hypertrophic and keloid acne scars
Raised acne scars require a different approach from indented scars. Treatments intended to stimulate collagen in a depression could aggravate a person who already produces excessive scar tissue.
Steroid injections
Corticosteroid medicine can be injected into a raised scar to reduce inflammation and collagen production. Several sessions may be needed.
Possible complications include thinning of the skin, visible blood vessels, colour change and a depression if too much tissue is reduced.
Silicone gel and sheets
Silicone gel or dressings may help flatten and soften some raised scars when used consistently over time.
They are less useful for mature, bulky keloids when used alone, but may form part of a wider management plan.
Cryotherapy
Cryotherapy freezes scar tissue. It may be used alone or alongside steroid injections for selected smaller keloids.
Pigment loss is a particular concern in darker skin tones.
Laser treatment
Vascular lasers may reduce redness and symptoms in raised scars. Other lasers may be used as part of a combination plan, but recurrence remains possible.
Surgical removal
Removing a keloid through surgery alone carries a substantial risk that it will return. Surgery is therefore often combined with steroid treatment, pressure therapy, radiotherapy or another recurrence-reduction strategy under specialist care.
Anyone who has previously developed a keloid should disclose this before microneedling, laser resurfacing, piercing, injectable treatment or elective surgery.
NHS treatment, private costs and choosing a clinic
NHS access to acne-scar procedures varies. Active acne and the risk of continuing scarring are more likely to receive NHS treatment than established scars treated primarily for appearance.
A GP may refer someone to dermatology when acne is severe, resistant to treatment, causing scarring or producing significant psychological distress.
Once acne is controlled, selected scar treatments may occasionally be available through specialist NHS services, but many procedures are restricted or locally commissioned. Cosmetic resurfacing is often self-funded.
Typical private costs in the UK
Prices vary considerably by region, practitioner and treatment complexity. Broad private-market estimates may include:
- Dermatology or scar consultation: approximately £150 to £350;
- Medical microneedling: roughly £150 to £350 per session;
- Radiofrequency microneedling: around £300 to £700 per session;
- Subcision: approximately £300 to £800 per session;
- Subcision with filler: often £500 to £1,200 or more;
- TCA CROSS: approximately £200 to £500 per session;
- Fractional non-ablative laser: roughly £300 to £800 per session;
- Fractional ablative laser: around £600 to £1,500 or more per session;
- Punch excision or elevation: priced by the number and complexity of scars; and
- Raised-scar injections: often £150 to £400 per appointment.
These are broad estimates rather than fixed prices. A full-face procedure in London or treatment by a specialist dermatologist or plastic surgeon may cost more.
Ask for the total treatment-plan cost
A low session price can be misleading when six appointments, prescription products and additional procedures are expected.
Ask for a written estimate covering:
- consultation;
- patch testing;
- anaesthetic;
- the procedure;
- aftercare products;
- follow-up;
- planned combination treatment;
- management of complications; and
- maintenance or repeat sessions.
Choosing a practitioner
A practitioner treating acne scars should be able to identify scar types and explain why the proposed technique matches them.
Ask:
- What type of scars do I have?
- Which scars will this treatment not improve?
- Should my active acne be controlled first?
- How often do you perform this exact procedure?
- Do you regularly treat my skin tone?
- What degree of improvement is realistic?
- How many sessions might I need?
- What are the risks of pigmentation and new scarring?
- Who manages infections, burns or poor healing?
- Can I see consistent photographs of your own patients?
Our guide to choosing a safe aesthetic clinic or practitioner explains how to verify professional registration, assess insurance, recognise sales pressure and check emergency arrangements.
Red flags
Be cautious when a clinic:
- recommends treatment without examining your scars;
- claims one machine treats every scar type;
- guarantees completely smooth skin;
- ignores active acne;
- does not discuss skin tone or pigmentation risk;
- sells a long package before seeing how you heal;
- uses inconsistent or heavily edited photographs;
- cannot explain the device or product being used;
- provides no written aftercare; or
- has no route for urgent clinical review.
Recovery, aftercare and realistic results
Scar remodelling is slow. Redness may settle in days or weeks, but collagen changes continue for months.
The appearance immediately after a procedure is not the final result. Swelling can temporarily make indented scars appear smoother, creating an early improvement that partly disappears as swelling resolves.
General aftercare
Follow the instructions provided for the specific procedure. Advice may include:
- cleaning the skin gently;
- using prescribed ointment or dressings;
- not picking crusts or peeling skin;
- avoiding active skincare ingredients temporarily;
- limiting heat, sweating and strenuous exercise;
- avoiding swimming while the skin barrier is open;
- not applying makeup until advised;
- using broad-spectrum sun protection; and
- attending follow-up appointments.
Sun protection
Freshly treated skin is more vulnerable to inflammation and pigmentation. Use the sun-protection method recommended by your clinician and avoid deliberate tanning.
Sunbeds do not prepare skin safely for laser treatment. Tanning may increase the risk of burns and pigment changes and can lead to treatment being postponed.
Warning signs after treatment
Contact the clinic promptly for:
- pain that is severe or worsening;
- spreading redness or swelling;
- pus, unpleasant discharge or fever;
- blistering beyond what was expected;
- skin becoming dark, grey or unusually pale;
- delayed healing;
- a cold-sore outbreak;
- new raised scar tissue; or
- pigmentation that is worsening rather than settling.
Seek urgent medical care when symptoms are severe, rapidly progressing or accompanied by systemic illness.
How much improvement is realistic?
No treatment can promise complete removal. The realistic goal is softer edges, shallower depressions, more even texture or reduced colour contrast.
The amount of improvement depends on:
- scar type and depth;
- treatment selection;
- the number of sessions;
- the body area;
- skin tone;
- healing response;
- active acne control; and
- the practitioner’s technique.
Published percentages can sound precise but may not predict an individual result. Scar-rating methods, photographs and definitions of improvement vary between studies and clinics.
Combination treatment
A mixed-scar pattern may require staged treatment. For example:
- TCA CROSS for ice-pick scars;
- subcision for rolling scars;
- punch elevation for selected deep boxcar scars;
- microneedling or laser for broader texture;
- vascular treatment for persistent redness; and
- pigment treatment for brown marks.
Combination treatment does not mean performing everything at once. A sensible plan allows the skin to heal and the result to be assessed before the next stage.
The emotional impact of acne scars
Scars can affect confidence, photographs, relationships and willingness to attend social or professional events. These effects deserve to be taken seriously.
However, treatment can become an endless search for flawless skin. Normal pores, slight asymmetry and subtle texture remain even after successful procedures.
If distress is severe, dominates daily life or continues despite repeated treatment, psychological support may be as important as another procedure. This does not mean the concern is imaginary; it means the emotional impact deserves appropriate care too.
Frequently asked questions
Do acne scars go away naturally?
Flat red or brown marks often fade gradually, although this can take months or longer. True indented and raised scars may soften with time but usually do not disappear completely without treatment.
What is the best treatment for acne scars?
There is no single best treatment. Ice-pick scars may respond to TCA CROSS or punch techniques, rolling scars often need subcision, and shallow boxcar scars may improve with microneedling or laser resurfacing. Mixed scars commonly require combination treatment.
How can I tell whether I have ice-pick, boxcar or rolling scars?
Ice-pick scars are narrow and deep, boxcar scars are broader with clearer edges, and rolling scars create shallow waves or depressions. A dermatologist or suitably trained scar practitioner can assess a mixed pattern more reliably than photographs alone.
Are red acne marks permanent?
Post-inflammatory redness often fades, but the process can be slow. Persistent vascular redness may respond to selected laser or light treatment. Red marks should not automatically be treated as indented scars.
Are brown acne marks scars?
Flat brown marks are usually post-inflammatory hyperpigmentation rather than structural scars. They may improve with sun protection, time and pigment-directed skincare or medical treatment.
Can skincare remove acne scars?
Skincare can treat active acne, support healing and improve pigmentation or fine surface texture. It cannot fully release tethered rolling scars, close deep ice-pick scars or replace tissue lost in deep depressions.
Does retinol help acne scars?
Retinoids may improve acne, pigmentation and subtle texture over time. They are unlikely to produce major correction of deep structural scars. Prescription retinoids may cause irritation and are not appropriate for everyone.
Does microneedling remove acne scars?
Microneedling can improve selected shallow boxcar and rolling scars, but it does not guarantee removal. Deep ice-pick scars and strongly tethered scars often need other treatments.
Is laser better than microneedling?
Neither is universally better. Ablative laser may produce stronger resurfacing but generally involves greater downtime and pigmentation risk. Microneedling may suit a wider range of skin tones but can produce more modest results. Scar type and practitioner expertise should guide the choice.
How many microneedling sessions are needed?
Many treatment plans involve three to six sessions, although the number varies according to scar depth, device, treatment intensity and response. Results develop gradually over several months.
Does subcision permanently remove rolling scars?
Subcision can create lasting improvement by releasing tethering bands, but scars may not become completely flat and some may reattach. More than one session or additional resurfacing may be needed.
Can filler treat acne scars?
Small amounts of filler may support selected rolling or boxcar depressions, often after subcision. It is not appropriate for every scar and introduces injectable risks. Temporary filler also requires future reassessment.
Can chemical peels remove deep acne scars?
Whole-face superficial peels generally do not correct deep scars. Focused TCA CROSS may help selected ice-pick scars, while stronger resurfacing peels have greater risks and require suitable medical oversight.
Is acne-scar treatment painful?
Discomfort varies. Topical or injected anaesthetic is often used for subcision, microneedling, laser and surgical treatments. Tenderness, heat or soreness may continue during recovery.
Can acne scars be treated on darker skin?
Yes, but the plan should account for a greater risk of post-inflammatory hyperpigmentation with some procedures. Choose a practitioner experienced with similar skin tones and avoid unnecessarily aggressive treatment.
Can acne-scar treatment make scars worse?
Yes. Burns, infection, excessive inflammation, poor wound healing or inappropriate treatment can cause pigmentation and new scarring. The risk can be reduced through correct treatment selection, experienced practitioners and careful aftercare, but it cannot be eliminated completely.
Should acne be completely clear before scar treatment?
Active inflammatory acne should usually be controlled first so that new scars are not continuing to form. Occasional minor spots do not always prevent every procedure, but the decision should be made by the treating clinician.
Can I have acne-scar treatment while taking isotretinoin?
The answer depends on the procedure, dose, condition of the skin and specialist assessment. Some treatments may need to be delayed, while others may be considered in selected circumstances. Tell every practitioner about current and recent isotretinoin use.
Is acne-scar treatment available on the NHS?
NHS access varies. Active severe or scarring acne may qualify for dermatology treatment, while established cosmetic scarring is often not routinely funded. Selected specialist services may treat severe scars according to local criteria.
How much does acne-scar treatment cost in the UK?
A session may cost from around £150 for basic microneedling to more than £1,000 for specialist laser or combination treatment. Total cost depends on the scar types, number of sessions, clinician and location.
How long does it take to see results?
Initial healing may take days or weeks, but collagen remodelling continues for several months. It is often too early to judge a procedure after only a few weeks.
Can acne scars be removed completely?
Complete removal is not a realistic promise. Treatment aims to make scars shallower, smoother, less sharply edged or less noticeable. Meaningful improvement is possible, but normal skin texture will remain.
