1. Simplify skin care: Don't stack too many products, especially all kinds of high-functional and nutritious essences. Choose at most one or two, and pay attention to whether the ingredients are mutually exclusive; Three core points: cleaning, moisturizing and sun protection. On the basis of these three steps, whitening, anti-aging and anti-wrinkle are realized. Use amino acid facial cleanser: Long-term use of soap facial cleanser will destroy the water-oil balance of facial skin, stratum corneum and skin barrier, so don't be too greedy for convergent facial cleanser that looks "clean" after washing. In addition, in addition to oily skin, it is recommended to use facial cleanser only at night and clean water in the morning, instead of washing the balance oil secreted by the face itself. Pay attention to sun protection: very important! ! ! The damage of photoaging to skin is irreversible. You should use sunscreen every day. Even if you work indoors, as long as it is daytime, there is ultraviolet light where there is a light source; If summer conditions permit, please wear sunglasses, an umbrella and a sunscreen shirt. After 5 to 10 years, you can see the skin condition of people who are sunscreen and not sunscreen.

2. Eat less sugar: Eating too much sugar is much more harmful than other ingredients, which will not only lead to obesity, cardiovascular and cerebrovascular diseases, but also greatly damage the oil secretion of sebaceous glands and accelerate skin aging, especially those who like acne. Eat less sugar.

3, eat more foods rich in vitamin C: As we all know, vitamin C is very important for whitening. The superposition effect of oral administration and external use is better, such as lemon, orange, grapefruit and kiwi fruit.
