Once your acne has healed, you will notice a red mark on your skin which looks like a scar but is actually a post-inflammatory change. Mostly, the redness is part of the healing process and will disappear in 6 to 12 months without a sign. However, if acne lesions develop repeatedly in the same area, then the healing takes place abnormally leaving behind a permanent scar.
Ice pick scars are sharp, narrow and go deep into the subcutaneous layer. In this case, the skin looks like it has been picked with an ice pick and hence the name.
Boxcar scars leave a deep angular dent in your skin which is quite similar to chickenpox scars. These scars mostly appear when your skin is destroyed due to seriously inflamed acne.
Rolling scars occur when the bands of tissue developed between the skin’s surface and deeper structures begin to pull at the skin, giving the skin a rolling, ‘wavy’ appearance. These scars look like pits or depressions on your skin.
