Acne is a skin disease which provokes the oily skin, the small cysts, the red buttons and the white heads to most of the teenagers. The acne pulls an inflammation extended by the opening of the hair. The acne is characterized by an oily skin and several types(chaps) of often associated buttons. We distinguish the rétentionnelles hurts (open blackhead or black dot(blackhead,negative point) and closed blackhead or microcyst), the inflammatory hurts (papule or button red, pustule or white head and voluminous painful red buttons or nodules), cysts and marks or scars which can be temporary or definitive. The affection begins most of the time in the adolescence and comes to an end most of the time before the age of 25 years See are quality content and some response to your question.
