Buy some laundry and see if it's ok.

Blackhead is a kind of oil hardening obstruction, which is caused by the fact that the oil in the skin is not discharged in time and the oil hardening has blocked the pores of sweet birch for a long time. The nose is the favorite part of oil. If it is not cleaned in time, a large number of dead skin cells are mixed in the oil, forming small spots. Therefore, oil control is the key to remove excess oil.

Although cleanliness is the main cause of the serious blackhead problem, if you have a friend whose skin is particularly clean, but her nose is always a little black, then you can guess that she probably has a bad stomach, not necessarily a disease, but a weak stomach, because the reflex part of the nose to the body is the stomach.

If the blackheads on the nose start to appear again after about two or three weeks, it's just a skin problem, which is normal, but if it becomes obvious after three or four days, you should pay attention to nourishing your stomach. You see, a person with rosacea has a bad stomach because he drinks too much and hurts his stomach.
