Post-Acne Marks

Look in daylight, not bathroom light. Press gently on the mark — red marks (PIE) blanch and briefly disappear under pressure; brown marks don't.

Brown: two to three months with treatment. Red: often three to six months, largely on their own. Both faster with sunscreen, both slower without.

No. Flat marks of any colour are not scars — they're temporary discolouration and they will go. A scar is a change in texture: an indent or a raised area. Those need in-clinic treatment, not skincare.

For brown marks, yes, moderately. For red marks, not really. Niacinamide is the more reliable all-rounder if you're only buying one.

Not on active acne — it spreads bacteria and can worsen inflammation. For textured scarring after acne has fully cleared, that's a clinic conversation rather than a home one.
