Why did you suddenly have a lot of acne?
There are some people often said that suddenly there is a lot of acne on the face. In fact, they existed a long time ago, but they did not show up. The early stage of acne is hidden in the skin's hair follicles and is hard to find. After about half a year, it will grow to the epidermis a little bit. If it happens to catch up with your endocrine abnormality, stay up all night, eat greasy and spicy, then it is likely to suddenly burst into red and swollen acne.
