The prevalence of acne is about 80% in the majority of the countries worldwide. Moderate and severe acne account for 20% of all cases. Prognostic factors of acne severity were identified: hyper seborrhea, an age of beginning of acne after 17 years or pre pubertray, extension of acne lesions to the trunk, stress for the two sexes, and notion of family acne (hereditary). The role of cigarette and food remains discussed. Acne of the adult (man and woman) is in increase and is estimated at 40% of the adults. In addition, recent epidemiologic data reveal that the acneic subject consults little the doctor (on average, one out of two) and, in the same way, only one young person out of two teenagers declaring a severe acne is treated. Actually, acne is regarded today as a chronic disease requiring treatment of induction and maintenance.
在世界上大多数国家，痤疮的患病率约为80%。中度和重度痤疮占所有病例的20%。已确定痤疮严重程度的预后因素：皮脂溢出、痤疮开始于17岁之后或青春期前、痤疮皮损扩展至躯干、两性的压力以及家族性痤疮（遗传性）概念。香烟和食物的作用仍在讨论中。成人（男性和女性）痤疮的发病率正在上升，估计占成年人的40%。此外，最近的流行病学数据显示，痤疮患者很少咨询医生（平均每两人中有一人），同样，每两名宣称患有重度痤疮的青少年中只有一人接受治疗。实际上，如今痤疮被视为一种需要诱导和维持治疗的慢性疾病。
