2. Acne Marks/ Pigmentation
When acne is inflamed, the skin will add some blood vessels to the site of inflammation, causing the acne to wither, and then after the inflammation, these red blood vessels will slowly disappear. Due to skin damage (inflammatory acne), melanocytes appear to protect the skin, but after the event, the melanin is not decomposed and accumulates in the affected area to become acne marks.
