When sweat penetrates the plug in the hair follicle and penetrates into sebum, it will become a cheese-like white mixture after a series of physical and chemical reactions.

After soaking in sweat, the blockage will not only expand, but also the wall of hair follicle, and the sebaceous gland tube of hair follicle will be blocked more tightly. Because the sebaceous duct of hair follicle is blocked, sebum can not be discharged, and acne begins to form.

This is also the reason why oily skin is prone to acne.

Long acne should also pay attention to the following matters in daily life:

1, pay attention to a light diet and don't eat greasy food. Spicy. Fried. Puffing waiting for food. There are too many junk toxins in these foods, which will directly affect the digestive function of the stomach.
