“The acne cleared, but the marks stayed.”
The most common presentation — pigmentation persists after lesions resolve.
↗Post-acne changes are colour, texture or both — red or brown marks left by inflammation, and depressed or raised scars left by tissue damage. The pathway depends on which one you have.
Post-acne changes are the skin's record of previous inflammation. They may be colour-related — red or brown marks — or structural — depressed or raised scars.
Development is closely tied to the severity of the original inflammatory acne and how quickly it was treated. Untreated deep acne almost always leaves structural change.
“Two rules govern scar treatment. Get the acne under control first. Never treat the scar without protecting from the sun.”
Symptoms named in the patient's own words alongside the clinical read.
The most common presentation — pigmentation persists after lesions resolve.
↗Post-inflammatory erythema (red) or hyperpigmentation (brown) — colour-only changes.
↗Atrophic scars — ice-pick, boxcar or rolling — where tissue was lost during inflammation.
↗The overall surface reads rough or pitted under raking light, even without deep scars.
↗A functional sign — foundation catches on depressed areas and disperses on colour marks.
↗Multiple scar types often coexist and need a combined protocol.
↗Post-acne changes fall into distinct categories — the pathway is different for each.
The pathway depends entirely on whether the change is colour, structure or both. Classification takes minutes and saves months.
Colour changes respond to peels and topicals; structural scars need resurfacing or collagen stimulation. Most cases combine both.
Fractional resurfacing and RF microneedling stimulate collagen in the scar bed — the pathway of choice for atrophic scarring that doesn't respond to topicals.
RF microneedling for deeper atrophic scarring and long-standing texture.
Supportive · ResurfacingFractional CO₂ resurfacing for widespread, mixed textural scarring.
Supportive · HydrationHyaluronic acid to support skin quality alongside scar-focused work.
Supportive · Colour marksSalicylic and TCA peels with vitamin C, niacinamide and retinoids for pigmentation.
A specialist reviews your acne history, classifies the scar type, and lays out a course that combines the right depth of intervention for your skin.
