I often hear the little sisters around me complaining that they have started to keep their mouths closed, whiteheads, and blackheads again. But what is the skin problem that makes every girl almost crazy, can you tell it?A closed mouth is also called "closed acne", and it is also a white head in everyone's mouth. To put it bluntly, too much oil is stuffed in the pores, and the mouth is blocked deep in the hair follicles if it can't be discharged.Unconsciously, it is not painful or itchy, but you can feel that the skin is very matte and has a real grainy feel, especially the high-hair areas like forehead, chin, and cheeks are maddening.Open acne means that the skin oil is blocked in the opening of the hair follicle. Although it is not completely blocked, it cannot be discharged. After being oxidized by the air, it forms what we call blackheads, especially on the sides of the nose. There will be a "strawberry nose".Shekou and blackheads are both in the acne category. Acne and acne are also collectively called acne, and acne becomes acne when it becomes inflamed, so if you want to fight acne, you must first solve the culprit of acne.
