Can skincare actually remove acne scars?

No topical removes a true scar. What over-the-counter actives do is improve appearance and texture over months: a retinoid normalises turnover and supports collagen, vitamin C supplies collagen building blocks, centella soothes and supports repair, and AHAs resurface rough tone. Flat brown or red marks (which people often call 'scars') aren't textural and do fade with brightening actives. But raised or deeply depressed scars are structural and need a dermatologist's procedural treatments to meaningfully change.

What is the best ingredient for acne scars?

For general post-acne texture, a retinoid is the most useful at-home active — it normalises cell turnover and supports collagen, gradually smoothing surface irregularity. Pair it with vitamin C (a collagen cofactor) by day, and centella to calm the inflammation that drives marks. Glycolic acid helps resurface rough tone. None of these fill a deep scar; for that, in-office procedures are the effective route.

What's the difference between acne marks and acne scars?

Acne marks are flat: brown post-inflammatory hyperpigmentation (pigment) or red post-inflammatory erythema (vascular). They sit level with the skin and fade with brightening and barrier care — see our acne-marks guide. Acne scars are textural changes in the skin itself: raised (hypertrophic/keloid) or depressed (atrophic). Texture changes are far harder to treat with topicals and, when significant, are best assessed by a dermatologist.

When should I see a dermatologist about acne scars?

See one for any raised or keloid scar (these are a medical condition and can worsen with the wrong treatment), for deep atrophic scars you want to meaningfully improve (microneedling, laser, subcision, and fillers outperform any cream), and for active acne that keeps causing new scarring — stopping the breakouts is the most important scar-prevention step. A dermatologist can also confirm whether what you have is a mark or a true scar, which changes the whole plan.

Data guide / Concern guide

The best ingredients for acne scars and texture

First, be honest about the kind of mark. Flat brown or red marks are not scars — they fade with the brighteners in our acne-marks guide. True scars are textural: raised/keloid scars are a medical matter for a dermatologist, and deep atrophic (icepick, boxcar, rolling) scars usually need in-office procedures. Topicals — retinol, vitamin C, centella, and AHAs — genuinely improve general texture and support collagen repair, but they improve the appearance, they do not erase a scar.

topicals improve appearance, not erase scars

Texture, not magic

The word 'scar' covers very different things, and they need different help. Flat marks — brown PIH or red PIE — are pigment or vascular, not texture, and respond to the brightening and barrier actives covered in our acne-marks guide. True scars are changes in skin texture. Raised (hypertrophic or keloid) scars are a medical condition and should be assessed by a dermatologist, who has prescription and procedural options. Depressed (atrophic) scars — icepick, boxcar, rolling — sit below the surface and usually need in-office treatment (microneedling, laser, subcision, fillers) to meaningfully change; topicals can offer slow, partial improvement at best. Where over-the-counter actives genuinely help is general post-acne texture and supporting the skin's collagen repair: a retinoid normalises turnover and thickens the epidermis over months, vitamin C supplies the cofactor for collagen synthesis, centella soothes scar-forming inflammation and supports collagen, and glycolic acid resurfaces rough tone. Set expectations honestly — these improve how marked skin looks and feels over months of consistent use; they do not remove a scar. Two rules apply to all of it: protect with daily SPF (UV worsens marks and texture) and, for significant or raised scarring, see a dermatologist rather than chasing a routine.

02 / Retinol

Retinol: the workhorse for texture and atrophic scars

For uneven texture and shallow (atrophic) acne scars, a retinoid is the most useful topical. Retinol normalises skin-cell turnover and, over months, thickens and reorganises the epidermis while supporting collagen — gradually smoothing surface irregularity. It will not erase a deep icepick or boxcar scar (those need in-office procedures), but it is the best at-home option for general post-acne texture, used consistently at night with daily SPF.

Study Topical 0.4% retinol applied for 7 days to naturally aged skin in vivo significantly increased epidermal thickness via keratinocyte proliferation (c-Jun upregulation), stimulated type I collagen, fibronectin, and elastin production, and activated the TGF-beta/CTGF pathway — producing effects comparable to retinoic acid without measurable retinoid-associated irritation. ¹
Study Topical 0.4% retinol lotion applied to elderly subjects (mean age 87 years) 3 times per week for 24 weeks produced significantly greater improvement in fine wrinkling scores than vehicle, with increased glycosaminoglycan and collagen expression in retinol-treated skin. ²

03 / Vitamin C

Vitamin C: collagen building blocks for scar repair

Because atrophic scars are essentially a local collagen deficit, vitamin C earns a place: it is an essential cofactor for the enzymes that build collagen, supporting the skin's own repair, and as an antioxidant it shields against further UV damage to the marked area. It is a sensible morning partner to a night-time retinoid — repair plus daytime defense, under sunscreen.

Review Acts as a cofactor for prolyl and lysyl hydroxylases, enabling hydroxylation of proline and lysine residues in procollagen, which is required for stable triple-helix collagen formation. ³

04 / Centella asiatica (Cica)

Centella: calms inflammation and supports collagen

Centella is the soothing member of the line-up. Its triterpenes stimulate collagen-related gene expression and collagen biosynthesis — relevant to the repair side of scarring — and its well-documented anti-inflammatory action calms the inflammation that drives both new breakouts and the marks they leave. Research on its triterpenes in keloid (raised-scar) fibroblasts is promising, but raised and keloid scars are a medical matter — see a dermatologist rather than self-treating them.

Study Centella asiatica triterpenoids alter gene expression in human fibroblasts, upregulating collagen synthesis and extracellular matrix pathways. ⁴
Study Asiaticoside-loaded ultradeformable vesicles improved collagen biosynthesis both in vitro and in vivo, demonstrating delivery-dependent efficacy. ⁵

05 / Glycolic acid (AHA)

Glycolic acid: resurface uneven texture

Exfoliating acids refine the look of rough, uneven post-acne texture by clearing dead surface cells and stepping up turnover — glycolic acid is the classic alpha-hydroxy acid for this, with documented epidermal and dermal effects. It is for general texture and tone, not for filling in deep scars, and it increases sun sensitivity, so daily sunscreen is non-negotiable.

Study Alpha-hydroxy acids, including glycolic acid, were first documented as therapeutic exfoliants for ichthyotic (hyperkeratotic) skin disorders; Van Scott and Yu's 1974 seminal paper established AHAs as agents capable of controlling keratinization. ⁶
Study Application of 25% glycolic, lactic, or citric acid lotion to forearms for approximately 6 months produced an approximately 25% increase in skin thickness, with increased acid mucopolysaccharides, improved elastic fiber quality, and increased collagen density in the dermis — significant reversal of epidermal and dermal markers of photoaging — without an inflammatory response. ⁷

Retinol is the best at-home option for general post-acne texture; give it months, with daily SPF.
For significant scarring, a dermatologist's procedural options outperform any routine — set expectations honestly.
