Causes & Symptoms of Acne Scars
Scars can be caused by deep wounds or severe acne that has repeatedly damaged the same area of your skin over time. Depending on their age and severity, scars may appear as discoloured, raised skin, or ‘atrophic’ that cause the skin to dip inwards slightly.
In the case of acne scars, the bacteria and dead skin cells cause your pores to become inflamed and eventually break. When wounded, your skin will be triggered to jump start the collagen production to restore the damaged cells, however in cases of bad acne it might need additional help to go back to its original condition.
There are two main types of acne scars: ‘hypertrophic’ and ‘atrophic’ acne scars. Hypertrophic scarring can occur when your skin produces too much collagen to fill the wound, so you’re left with a slightly raised area on the surface of your skin. Atrophic scarring can be caused by a loss of tissue beneath the surface, which the body cannot replace. Therefore, the acne scars give your skin a dimpled appearance.
