How does inflammation affect the risk of scarring?
Inflammation is the body’s response to injury and infection. With acne, P.acnes bacteria inside plugged, oily skin pores multiply quickly. This triggers an immune system reaction seen as redness, heat and swelling in and around spots. If intensive, the inflammation can damage normal skin structures, leading to scarring. Picking and squeezing acne spots increases inflammation so avoid doing this to limit the risk of scarring.
