What types of acne scars are there?

There are four types of acne scars which are the most common. These are:

Ice Pick Scars

Ice pick scars are deep, narrow scars which form pits in the skin. They are among the most common.

Rolling Scars

Rolling scars create a wave-like appearance on the skin's surface due to their wide and shallow depth.

Boxcar Scars

As one might expect from their name, boxcar scars have angular, well-defined edges usually on the temples or cheeks. Their appearance is similar to chickenpox scars.

Hypertrophic / Keloid Scars

Hypertrophic scars are raised scars which stay within the boundary of the original wound and can reduce in size with the passage of time. Keloid scars, on the other hand, are overgrowths of tissue which expand beyond the original wound site. The scar is rubbery and firm and may itch. Often they form to be much larger than the original wound.
