Acne and Scar pigmentation

Acne scarring is due to touching and squeezing spots. This damages small veins, glands and tissues surrounding the spots which creates scarring," he says. Unlike acne scarring, post-inflammatory hyperpigmentation is simply a form of skin pigmentation (like sun damage), which occurs as a result of trauma to the skin. Hyperpigmentation is an umbrella term that refers to spots on your skin, which could range from melasma to age or liver spots. Acne scarring too comes under this. The raised dark portion of the acne scar is known as hyperpigmentation. The main cause of the same is too much melanin.
