Acne scars

Tell acne scars from flat marks, see what products cannot fix, compare procedure options and timelines, and know when specialist care may be worthwhile.

Short answer

First control ongoing acne, stop picking, and use sunscreen; then decide whether the change is flat colour, a dent, or a raised scar. Flat colour can fade over months. Creams cannot refill a dent or flatten a raised scar; procedures usually improve rather than erase scars.

  • Not a structural scarFlat colour mark

    Colour changes, but the skin surface stays level.

  • Depressed scarIce-pick

    A small opening with a narrow, deep indentation.

  • Depressed scarBoxcar

    A wider round or oval depression with defined edges.

  • Depressed scarRolling

    A broad, shallow depression with smooth, sloping edges.

  • Raised scarHypertrophic

    Firm raised tissue that stays within the original acne spot.

  • Raised scarKeloid

    Raised tissue that extends beyond the original acne spot.

What the diagram shows

A flat colour change does not indent or raise the skin. Ice-pick, boxcar, and rolling scars are depressed; hypertrophic scars and keloids are raised.

Quick answer

What matters most for acne scars.Why this is the answer

The likely benefit, a sensible first step, how long to give it, and when to get help.

Which pattern matters?

Flat colour can fade; indented or raised scars usually need procedures.

Why this is the practical answer

Control active acne first and protect the skin from sun. Flat post-acne colour may fade over months. A retail topical cannot reliably lift an indented scar or flatten a raised scar, and structural-scar procedures often require several sessions. [1] [2] [3] [4]

Check this first

Control active acne and protect the skin

Prevent additional inflammation, avoid picking, use non-comedogenic sun protection, and allow recent colour changes time to settle. [1] [3]

How much change is realistic?

Allow recent colour to evolve

Flat post-inflammatory colour can improve gradually over months. A home active should be stopped sooner if irritation is adding inflammation. [1] [2] [3]

When should I decide?

Judge improvement, not erasure

Colour may fade over months. Structural-scar procedures often require several sessions, and current evidence does not identify one best option for everyone. [1] [2] [4]

Do you need to spend more?

Do not spend heavily on a cream marketed for indented or raised scars.

Why this may be enough

A lower-cost sunscreen or a suitable acne treatment can help prevent additional darkening and new scars. A retinoid may help flat colour or very mild surface texture over time, but the featured retail serum will not correct an indented or raised scar. [1] [2] [3] [4] [5] [6]

Pay more only when it helps with: professional assessment and a scar-specific procedure when an indented or raised scar—not flat colour—is the treatment target.

Understand the pattern

What to know about acne scars

Acne can leave a flat colour change, a depressed scar such as an ice-pick, boxcar, or rolling scar, or less commonly a raised hypertrophic scar or keloid. These changes need different approaches, so identifying the feature is more useful than choosing a product from a generic “scar” label. [1] [2]

This guide focuses on realistic decisions. Colour changes often improve gradually, while structural scars may become less noticeable with time or treatment but usually cannot be completely removed. [1] [2] [4]

Open the optional recap

A source-linked summary that separates flat marks from structural scars and places safety before cosmetic escalation.

Colour change or altered texture

Usual pattern. Flat post-acne colour is often not a true scar. Depressed or raised texture represents structural scarring and needs scar-specific assessment. [1] [2]

Control active acne and protect the skin

Conservative first step. Prevent additional inflammation, avoid picking, use non-comedogenic sun protection, and allow recent colour changes time to settle. [1] [3]

Judge improvement, not erasure

Reassess. Colour may fade over months. Structural-scar procedures often require several sessions, and current evidence does not identify one best option for everyone. [1] [2] [4]

New scars, deep acne, or a complication

Seek care sooner. Seek earlier assessment for ongoing nodules, new scarring, an enlarging raised scar, or pain, blistering, warmth, or drainage after a procedure. [1] [3] [5] [6]

Use this as a decision path, not a diagnosis.

Start with the box that best matches what you notice, and open a numbered source whenever you want the supporting detail.

First decide whether the change is colour or texture

If the skin remains flat and only the colour has changed, the mark is more likely lingering redness or extra pigment after inflammation than a scar. These marks can take months or longer to fade, especially when inflammation continues or sunlight deepens the contrast. [1]

A depressed scar changes the skin surface. Ice-pick scars are narrow and deep, boxcar scars are wider depressions with more defined edges, and rolling scars have sloping edges or tethering beneath the skin. Raised scars require a different assessment because they contain excess scar tissue. [1] [2]

  • Flat colour change: often fades gradually and is managed alongside the cause and sun protection. [1]
  • Depressed scar: an indentation caused by loss or tethering of deeper tissue. [1] [2]
  • Raised scar or keloid: firm excess scar tissue that may itch, hurt, or extend beyond the original spot. [1] [2]
  • Mixed patterns are common, which is one reason combination treatment may be discussed. [2]

A photograph cannot reliably grade every scar

Lighting can exaggerate or hide depressions. A clinician also considers active acne, skin tone, keloid tendency, medications, goals, downtime, and budget. [2]

Prevent new scars before treating old ones

Current guidance prioritizes controlling active acne. Deep, painful, long-lasting inflammation carries a greater scarring risk, and persistent picking or squeezing adds injury. New nodules, cysts, or early scars are reasons to seek care rather than waiting through repeated product trials. [1] [3]

Keep the routine gentle and use non-comedogenic broad-spectrum SPF 30 or higher. Sunscreen helps limit additional darkening, while camouflage makeup can reduce visibility without altering the scar. Neither approach rebuilds lost tissue. [1] [2] [3]

  • Continue an effective acne-maintenance plan when advised. [1] [3]
  • Do not squeeze, scratch, or repeatedly inspect scars with tools. [1] [3]
  • Use sunscreen consistently before judging the colour of a recent mark. [1]
  • Treat distress and quality-of-life effects as valid reasons to request help. [3]

What may help

Options that may help

You usually do not need all of these. Start with the option that best fits what you notice, then keep the rest of the routine simple while you see whether it helps.

Treat active acneBest fit. Reduces continuing inflammation and helps prevent additional scars.See cautions and sources

Best fit. Reduces continuing inflammation and helps prevent additional scars. [1] [3]

Watch for. Deep, painful, or scarring acne usually needs earlier clinical care rather than repeated self-treatment. [1] [3]

Sun protection and camouflageBest fit. Limits further darkening and can make marks or scars less visually prominent.See cautions and sources

Best fit. Limits further darkening and can make marks or scars less visually prominent. [1] [2] [3]

Watch for. These approaches do not restore lost tissue or flatten a raised scar. [1] [2] [3]

Topical retinoid or salicylic acidBest fit. May make very mild scarring less noticeable while also addressing acne or clogged pores.See cautions and sources

Best fit. May make very mild scarring less noticeable while also addressing acne or clogged pores. [2] [3] [4]

Watch for. Evidence for established structural scars is limited. Irritation can worsen colour change, and topical retinoids are avoided in pregnancy. [2] [3] [4]

Clinician-performed proceduresBest fit. Can target selected depressed or raised scars after assessment of scar type and skin.See cautions and sources

Best fit. Can target selected depressed or raised scars after assessment of scar type and skin. [2] [3] [4] [5] [6]

Watch for. Benefits vary and may require several sessions; burns, infection, pigment change, and further scarring are possible. [2] [3] [4] [5] [6]

Keep expectations modest for treatment applied at home

The American Academy of Dermatology notes that a topical retinoid or salicylic acid may make mild scarring less noticeable. These ingredients are better established for acne and clogged pores than for rebuilding an established deep scar, so the expected benefit should be described as limited. [2] [4]

When the main concern is a flat dark mark, treating active acne, minimizing irritation, and protecting against ultraviolet exposure may allow gradual fading. Stronger exfoliation is not automatically faster and can create inflammation that prolongs discolouration. [1] [3]

  • Introduce one leave-on active at a time. [2] [3]
  • Do not apply an acne active to raw, recently treated, or broken skin. [2]
  • Avoid topical retinoids during pregnancy or while planning pregnancy. [3]
  • No oil, vitamin product, or scar cream is proven to fill a deep acne pit. [2] [4]

Match procedures to the scar rather than a popularity ranking

A dermatologist may consider microneedling, fractional laser, chemical peeling, subcision, filler, punch techniques, radiofrequency, or minor scar surgery for depressed scars. Raised scars may be approached with injections, laser, freezing, or combinations. The choice depends on the scar’s shape and depth as well as the person’s skin and risk profile. [2]

The evidence base has important limits. A Cochrane review found small, varied studies and insufficient evidence to select a universal first-line procedure. NICE advises specialist consideration of selected procedures for severe scarring that persists a year after acne has cleared; that recommendation is not a claim that one procedure is best for every scar. [3] [4]

  • More than one session is often needed. [2] [4]
  • A combination plan may target colour, texture, and tethering separately. [2]
  • Improvement is a more realistic goal than complete removal. [2] [4]
  • Ask how the proposed option performs in skin with a similar pigment response and keloid risk. [2] [5]

Authorization is not a guarantee

FDA authorization of selected microneedling devices for improving the appearance of facial acne scars means specific devices were reviewed for that use. Results still vary, and complications can occur. [5]

Treat scar procedures as medical decisions

The FDA recommends trained care for microneedling devices that penetrate living skin. Reported risks include bleeding, bruising, infection, reactivation of cold sores, and darker or lighter patches. Radiofrequency microneedling has also been associated with serious burns, scarring, fat loss, and nerve damage. [5]

The FDA separately warns against unsupervised high-strength TCA, glycolic, salicylic, and lactic acid peels because they can cause chemical burns, infection, pigment change, and disfiguring scars. Seek prompt care for significant pain, blistering, spreading redness, drainage, or an unexpected change after a procedure. [6]

  • Ask which device or peel is being used and who is performing it. [5] [6]
  • Discuss medications, recent isotretinoin, cold sores, keloids, pregnancy, and healing problems in advance. [5]
  • Confirm the expected downtime, aftercare, number of sessions, and total cost. [2] [5] [6]
  • Do not combine a procedure with home acids or retinoids unless the treating clinician gives a schedule. [2] [5] [6]

How long to try it

How to reassess an acne-scar plan

These are decision points rather than promises of complete removal or a fixed treatment course.

Name the feature and stop new injury

Start. Record whether the concern is flat colour, a depression, or a raised area; treat active acne and stop picking before selecting scar treatment. [1] [2] [3]

Allow recent colour to evolve

Early review. Flat post-inflammatory colour can improve gradually over months. A home active should be stopped sooner if irritation is adding inflammation. [1] [2] [3]

When a dent or raised scar still bothers you

Decision point. Once acne is controlled, a dent or raised scar that still bothers you is a reasonable reason to discuss scar-matched options, evidence limits, downtime, pigment risk, and likely number of sessions. [2] [3] [4] [5]

Burn, infection, or unexpected change

Stop sooner. Stop self-directed treatment and seek prompt care for severe pain, blistering, spreading redness, drainage, or a new changing lesion. [5] [6]

Common questions

Is a flat dark acne mark a scar?

Usually not. A flat colour change is often post-inflammatory hyperpigmentation, while a true scar changes the skin’s texture or shape. Both can occur together.

Which procedure is best for acne scars?

There is no single best procedure. Ice-pick, rolling, boxcar, and raised scars respond differently, and current comparative evidence is too limited to support one universal ranking.

Can I microneedle or use TCA at home?

Medical-depth microneedling and high-strength chemical peels can cause infection, burns, pigment change, and additional scarring. FDA guidance supports trained professional care rather than unsupervised use.
