You can adopt the following nursing methods: (1) Diet adjustment: You should eat more foods containing a lot of vitamin C, such as tomatoes, plums, oranges, hawthorn and oranges, lemons and wild jujubes. In addition, eat more fresh green leafy vegetables. Try not to smoke, drink alcohol and drink less strong tea.

Mask bleaching: generally weekly 1 time. You can go to a beauty salon to do it, or you can apply it with a commercially available bleached soft film. Then there is self-made mask bleaching, such as cucumber mask (the cucumber skin is rubbed into filaments or sliced and applied to the face), strawberry mask (the strawberry fruit is cut in half, and then the juice is directly applied to the face and neck), tomato mask with milk (mashed mature tomatoes, mixed with appropriate amount of milk and applied to the face), lemon mask (lemon juice mixed with appropriate amount of flour applied to the face), protein hydrogen peroxide mask (1 piece)

Use whitening skin care products: There are many kinds of skin care products that can remove spots and whiten skin. The main additives in traditional products are white mercury, sulfur, hydroquinone, betamethasone and azelaic acid, etc. Improper use of these products will cause skin irritation. Traditional Chinese medicine additives include Radix Astragali and Radix Angelicae Sinensis. The newly emerging additives are mostly biological products, such as kojic acid and its derivatives, arbutin, seaweed extract, fruit acid and placenta. In addition, skin care products containing vitamins E and C and superoxide dismutase (SOD) also have whitening effect.

When we use whitening skin care products, we should also choose according to the nature of our skin, and if necessary, we should do patch test first. If there are any adverse reactions (such as tingling, erythema, edema, etc.) during use, stop using them immediately and treat them in time.
