Is it a scar or post-inflammatory hyperpigmentation (PIH)?
A scar involves a structural change in the skin, such as:
β’ An indentation
β’ A raised area
β’ A change in skin texture
PIH, on the other hand, is primarily a change in colour.
Understanding the difference matters because you're dealing with different skin changes.
Not every mark left after acne is a scar.
