Acne scarring occurs when the visible remnants of acne are permanently left on the skin after the acne itself subsides. True scarring is to be distinguished from macules, or reddish spots that mark the site of prior acne.
What Causes Acne Scars?
Acne scarring is caused by a variety of factors. When acne is produced on the skin as a response to sebum, the body may attempt to target the inflammation with white blood cells. Once the inflammation has subsided, however, the tissue may have yet to be fully repaired, and as such, scar tissue will show. It is important, however, to note that marks on the skin are not necessarily scars; simple marks will usually disappear within seven months. |
