The cause of your acne may be inflammatory in nature, or related to something else. It usually affects an area of skin that has the densest population of sebaceous follicles (oily skin). These areas include your face, upper chest and back.

An acne attack, or acne scarring that doesn’t disappear can result in psychological effects that include poor self-esteem and depression. Genetics and even the quality of sleep you get, your stress levels, your diet, what you drink, sun exposure, smoking and hormonal and psychological changes can play a role in an acne breakout.

Acne scaring results when the acne becomes inflamed and cystic acne occurs. Scarring happens when the pores on your skin become larger due the accumulation of excess oil, bacteria or other impurities. This accumulation in the pores causes the follicle to break. As a result, the impurities spread to the dermis where it damages the healthy skin tissue so the acne scar removal becomes essential. This, combined with the over-production of collagen to heal the wound leads to the formation of a scar.

There are different types of acne scaring and the type of scarring that occurs on your skin depends on what damage there is on your skin and the skin repair process.
