First of all, 20 years old is the best period of skin in a person's life. At this time, skin cells are very active, metabolism is also very strong, skin moisture is sufficient, and it is also smooth and elastic. During this period, skin care should be carried out from two aspects, one is sun protection, and the other is oil control. Sun protection-this is a nursing topic that we should pay attention to all our lives. If we can do a good job of sun protection at this time, it will be very good for the maintenance of our skin for a lifetime, because most people's skin is sunburned. Oil control-80% of young women will be confused about "acne", so oil control becomes very important. The focus of this period should be to choose some skin care products with strong cleanness and refreshing style. Don't use this nutritious and heavy cosmetic, because it will clog pores. On the other hand, I suggest that you only wear light makeup, and try not to use heavy liquid foundation and cream, which will clog pores and cause coarseness. Finally, you should also pay attention when washing your face, because there is more oil secretion when you are young, so you should add some massage when washing your face. Massage should be from the inside out, from the bottom up, especially in the triangle with heavy oil secretion. Intensive massage can excrete fat, so the massage when licking your face can make your skin completely clean. Skin care is not only a face problem, but also an internal strength problem ~ ~ ~ Now the environmental pollution is so serious. It is very important to always pay attention to whether the air in your residence and office is ventilated and try to choose green food to eat. Fruit. Drink plenty of boiled water (8 glasses of water a day for women).
