Acne Scar Treatment

Acne scars are not one thing, and that is the single most useful fact to know before starting treatment. Different scar types respond very differently, and a plan that ignores the distinction produces disappointment.

Rolling scars — broad and shallow with sloping edges — respond best. Shallow boxcar scars respond reasonably. Deep boxcar scars respond less.

Ice-pick scars — narrow and deep — respond least, because the depth is beyond what surface collagen induction meaningfully reaches. They often need a different approach entirely.

Raised and keloid scars are a separate problem and are not treated this way at all.

Most people have a mixture. A useful assessment tells you which of yours are likely to change, which are not, and roughly what proportion of your overall appearance that represents.

If acne is still active and new inflammatory lesions are still forming, scar treatment is working against an ongoing process — new scars keep arriving while the old ones are treated, and inflamed skin is a poor candidate for a treatment based on controlled injury.

Getting the acne genuinely under control first, which may mean a dermatology referral rather than a cosmetic treatment, is the step that makes everything afterwards worthwhile. Sometimes the right answer at a first consultation is "not yet".

Microneedling is among the better-studied approaches for atrophic acne scarring. Systematic reviews of randomised trials report meaningful improvement in scar severity, used alone or alongside complementary treatments, and it is generally well tolerated.

"Improvement" is the word the evidence supports. Shallower scars, softer edges, more even texture — not a surface returned to how it looked before the acne. People who expect improvement are usually pleased with improvement; people who expect erasure are disappointed by exactly the same result.

In this region a large proportion of patients have medium to darker skin, where the main concern with resurfacing is post-inflammatory hyperpigmentation.

Microneedling has a comparatively favourable profile because it does not remove the epidermis the way ablative resurfacing does. Comparatively favourable is not risk-free: appropriate settings, avoiding recently sun-exposed skin, and disciplined sun protection afterwards are what keep it that way.
