Acne scars occur after the skin gets damaged or inflamed. The wound healing is disrupted and small pits are formed in the skin; acne scars. In some cases, the scars can irritate and get red. These scars are located somewhat on top of the skin and sometimes can cause an itchy feeling
Acne scars can be divided into three types:
- Ice pick scars: 1-2 mm large scars that penetrate deep into the skin
- Larger depressed scars
- Multiple atrophic muculae: initially purple in colour, they become white and less noticeable after a number of months
