Why don't I eat spicy food, smoke and drink, work and rest normally, and pay special attention to my diet for my health. 10 years, my face is still covered with acne.
The reasons are unknown. Maybe you pay too much attention to "maintenance" that your physiological metabolism doesn't follow the track of your biological clock. If you are 35 years old, that is a big problem; If you are not 30 years old, you can relax and pay attention to the combination of activities and rest. When you are old and want to grow acne, acne will ignore you.
