1. Eat more fresh vegetables and fruits, drink more water and eat less spicy food. 2. Keep your face clean every day. Wash your face with cleanser in the morning and evening. You can also drink more water in some ways, more than 2000 ml per day. 3. Pay attention to proper sleep. Sleeping too long will slow down the blood circulation, retain moisture, relax the skin and make the pores look big and scary. Adults should sleep 8 to 9 hours a day. 4. Don't over-clean your skin. Because excessive cleaning will stimulate cells to secrete more oil, forming a vicious circle.
