◆ Acne is a hardened oil blockage, mainly a "plug" composed of sebum, cell debris and bacteria, which is formed by blocking the mouth of hair follicle. It often occurs in areas rich in sebaceous glands such as face, back and chest. Because it occurs mostly in adolescence, it is also called acne. Wash the affected area with hot water to reduce sebum. Eat less greasy, spicy and fried food. Eat more vegetables and fruits. Vitamin B2, vitamin B6, vitamin B complex preparation and vitamin E have certain curative effects.
