Which path fits your question?
Start with the outcome you want to understand. A cosmetic ingredient claim and a treatment question need different evidence.
Swipe the table to read both columns →
| Your question | What to do with the evidence |
|---|---|
| Is the area flat and darker after acne? | This may be post-inflammatory hyperpigmentation rather than a scar; controlling new breakouts and sun protection are relevant. |
| Is there a pit or raised texture? | A scar is a different problem from a flat color mark. Seek a clinician’s assessment before buying a pigment-focused serum for it. Sources: [1] |
| Do products make marks darker or skin sting? | Simplify the routine and avoid the irritating product; irritation can contribute to discoloration. |
| Considering a peptide serum? | Ask for exact-formula pigment outcomes. Without them, treat it as an optional cosmetic rather than a dark-spot treatment. |
First identify the concern
AAD distinguishes flat post-acne color changes from acne scars. Flat post-inflammatory marks often fade over time, while scars involve a different appearance and can require different care.

Protect against further darkening
AAD recommends sunscreen as the start of dark-spot care. Its guidance for darker skin tones specifically mentions tinted broad-spectrum SPF 30 or higher with iron oxides for visible-light protection.

Address the driver before an extra serum
When breakouts are ongoing, acne care matters because new lesions can leave more marks. AAD describes topical retinoids among acne treatments that can also help some post-acne dark spots, but suitability and irritation need consideration.

Common questions
Are acne marks the same as scars?
No. AAD describes flat post-inflammatory color spots as distinct from scars.
Sources: [1]
Does a peptide serum fade melasma or dark spots?
The AAD guidance reviewed here does not establish a finished peptide-serum treatment for those conditions. Do not substitute an ingredient claim for condition-specific evaluation.
