Ice pick scars are a type of acne scar, which are characterised by their "pitted" appearance, which looks like the skin has been punctured. They are most commonly associated with severe types of acne.
Ice pick scars usually occur as the result of serious or chronic, inflammatory acne. Picking or squeezing spots can increase the likelihood of developing ice pick scars.
You can develop ice pick scars anywhere you have had acne. They are most usually found on the face.
People who suffer from chronic acne are more susceptible to ice pick scars.
