Acne scars- why do they form?
When we get acne many times it resolves without getting infected. This kind of acne leaves hyper pigmentation that fades over a time. When acne becomes infected, it spreads deeper inside and damages the collagen in the dermal layer. As the inflammation increases, more of skin tissues are killed and when the acne gets treated, it leaves a scar, which is normally a deep scar. The depth depends upon the damage done by acne, which depends upon it’s severity.
