Dark Marks After Acne: Pigmentation or a True Scar?
Post-inflammatory hyperpigmentation is not an indented scar. Knowing the difference prevents mismatched treatment and unnecessary irritation.

The key difference
If the skin surface is flat but remains darker after a spot heals, the problem is usually post-inflammatory pigment. A true scar changes the contour, depth or texture of the skin.
Scar-resurfacing procedures are not the logical first step for a flat dark mark alone.
What usually helps
- Control active acne so new dark marks stop appearing.
- Use sunscreen consistently to reduce persistence and worsening of pigment.
- Azelaic acid or retinoids may be useful in selected routines depending on skin tolerance and the clinical picture.
- Avoid aggressive exfoliation or stacking too many irritating actives.
Why pigment can worsen while you are treating it
Irritation itself can trigger more pigment, especially in skin that hyperpigments easily. A slower, better-tolerated plan can outperform an aggressive routine that keeps the skin inflamed.
When clinic procedures enter the discussion
Persistent pigment despite controlling the cause and using consistent home care may be assessed for selected peels or energy-based treatments, with careful attention to skin tone and post-inflammatory pigment risk.
