Acne vulgaris is a skin condition which commonly affects teenagers and adults. Many people get blackheads, whiteheads, pimples, and pustules. Changes in hormone levels like androgens and testosterone can cause acne, as well as overgrowth of bacteria, especially P. acnes. Individuals who get laser, PRP, or other skin treatments that remove layers of the skin, or introduce punctures to the skin, need to be especially vigilant in cleansing post-procedure with effective facial cleansing.
