Type #1: Depressed or atrophic acne scars. About 80 to 90% of people with acne scars have this type. During the skin’s healing process, too little collagen is deposited to fill up the holes, leaving indents.
There are 3 kinds of depressed scars. Sometimes people have all 3 forms of atrophic scars. (Images courtesy Dr. Jerry Tan and Dr. Ben Barankin)
• Ice-pick: narrow, deep and V-shaped.
• Boxcar: a wide, round or oval opening at the surface with a box–shaped hollow into the skin. These can be deep or shallow.
• Rolling: the widest scars with a rippled, layered look.
Some features of these scars:
- – Pink, thickened, raised lumps
- – Easily visible, appear on the head, neck and trunk
- – May itch and hurt (but less than keloids)
Type #3– Keloids
These are uncommon, reddish-purple, large acne scars. Keloids develop as a result of an excessive healing process that is likely inherited. These scars may grow and can be disfiguring.
Some features of keloids:
• More common in darker skin types.
• Mainly appear along the jawline, neck, chest, shoulders, and upper back.
• More likely in people under the age of 30
• Feel rubbery
• Extend beyond the original scar site
• May itch and hurt
