Acne Scars

Dark Marks After Acne

Flat brown or grey marks can remain after acne, especially when inflammation or picking is significant.

In plain language

What this term means.

Post-inflammatory hyperpigmentation is excess pigment produced after skin inflammation. It is not a permanent scar, although fading can be slow.

What patients notice

Professional assessment

How a consultation may clarify the concern.

Active acne and scar types are assessed separately
Lighting from different angles helps identify depth, sharp edges, tethering and colour change

Treatment approach

Options follow the diagnosis

  • Match each scar pattern to the most suitable technique
  • Use staged combination plans when one method cannot address every scar

Avoid

What not to do

  • Do not perform deep home needling, strong peels or scar extraction
  • Avoid promises that scars can be completely erased

Care

Useful next steps

  • Control new acne and use sun protection to reduce contrast from post-acne marks
  • Allow adequate healing time between procedures

Frequently asked

Questions to take into consultation.

A photograph can document appearance but may not show texture, depth, scalp findings or warning signs. A diagnosis and personalised plan may require history and in-person examination.

Not usually. The appropriate pathway depends on the cause, severity, skin or hair characteristics, previous treatment, medical suitability and the result you hope to achieve.
