THE DIFFERENT TYPES OF ACNE SCARS
Depressed acne scars (Atrophic)
Depressed or pitted acne scars are the most common. A depressed scar sits below the surrounding skin. Depressed scars are formed when not enough collagen is made while the wound is healing
There are three main types of scar that this form of acne leaves behind:
These are wide, U-shaped scars that have sharp edges. They can be shallow or deep. The shallower they are, the better they respond to skin resurfacing treatments.
These are narrow, V-shaped scars that can go deep into the skin. They can look like small round or oval holes, like a chickenpox scar. These are the most difficult scars to treat because they can extend far under the surface of the skin.
These are wide depressions that typically have rounded edges and an irregular, rolling appearance.
