If you mean dark marks left after acne, these are often post-inflammatory hyperpigmentation (PIH) rather than true scars. They usually fade, but it can take several months.
What helps most
Morning
- Gentle cleanser.
- Vitamin C or niacinamide to help brighten uneven pigmentation.
- Moisturizer.
- Broad-spectrum SPF 30–50 every day. This is especially important because UV exposure can make dark marks darker and prolong them.
Night
- Gentle cleanser.
- Adapalene 0.1% or another retinoid can gradually improve acne and pigmentation. Start 2–3 nights/week and increase as tolerated.
- Moisturizer.
If you want an additional pigment-targeting ingredient, azelaic acid (10–20%) is a good option and can help both acne and dark marks.
Avoid
- Picking or squeezing pimples.
- Harsh scrubs and frequent exfoliation.
- Using several strong actives at once—irritation can actually worsen pigmentation.
- DIY lemon juice or bleaching remedies.
How long? You may notice improvement in 6–12 weeks, but deeper/darker marks can take several months to fade.
If the spots are indented or raised rather than flat and brown/gray, they’re more likely acne scars, which generally need different treatment.
If you tell me your skin type (oily/dry/sensitive), skin tone, and what products you’re currently using, I can suggest a simple routine for your specific situation.
