Acne scarring is the marking left on the skin after a spot or acne break out has healed. It can either be raised (Hypertrophic) or depressed (atrophic), it may also appear as darker marks on the skin where the lesion has been, however this is not true acne scarring, rather post inflammatory hyperpigmentation. It may also manifest at hypopigmentation lack of colour in the scar site, or Erythema (permanent redness) Atrophic scarring may appear as rolling; shallow depressed scars with gentle sloping edges, boxcar; broad with steep defined edges and icepick; deep narrow scars.
When an inflamed acne spot erupts the pore is engorged with oil, dead skin cells and bacteria, this can break the wall of the pore, and result in damage to the skin tissue around. It as the body clears the infection and tries to repair the damage the body produces new collagen, if it produces too little or too much a scar will result.

Genes play a large role, anyone who has a family member who developed acne scars has an increased risk Although we know what increases a person’s risk of developing acne scars, it is not possible to predict who will develop acne scars. Even people who have all the risk factors may not scar.
