Trick one, after the sun moisturizing repair
The principle that the skin is tanned is actually that the skin barrier function is impaired, causing a large loss of water, the skin's resistance is reduced, and eventually the melanin is increased, and the person is darker. Therefore, the skin that has just been sunburned must be repaired with water. On the night of being sun-dried, you can apply it with a hydrating mask or use a moisturizing lotion. Replenishing moisture not only relieves the damage and sensitivity caused by UV rays, but also paves the way for subsequent whitening.
Trick 2, grasp the golden age of whitening
After 3 days of hydration repair, it is the golden age of whitening. Some friends said that when they are tanned, they will not come back. Actually, it is not because melanin is metabolized. However, some people have faster metabolism of melanin and some people are slower. Using whitening products is to make your white back faster.
In the choice of whitening products, of course, choose a mild whitening product. When you see the following ingredients, you can basically buy them: vitamin C, salicylic acid, retinoic acid, tranexamic acid, and other various extracts (licorice, ginkgo, aloe, etc.). They basically whiten the skin by reducing the synthesis of melanin, inhibiting the synthesis of melanin, and promoting the metabolism of melanin.

If you don't want to become a "copper", you only need three strokes after whitening.
When it comes to whitening products, let's talk to you about whitening foods and whitening needles that are widely spread on the Internet. Can you whiten them?
Whitening food, can be whitened but limited in effect
The lemonade is white, I believe everyone has heard it, the reason is that the lemon has a high vitamin C content. In theory, vitamin C can actually inhibit the formation of melanin, but the problem is that the vitamin C we usually consume is basically digested. If you want to have an effect on the skin, how much do you have to eat? And drink so much lemonade, one It is caused by too much stomach acid, and another side effect is damage to the enamel, which causes various dental problems.
Whitening needle, not recommended
The main reason is that the current state has not officially approved the whitening needle review. In order to highlight the efficacy of their own whitening needles, some beauty salons may add large doses of prohibited ingredients such as hormones, lead and mercury to the formula, causing the illusion of temporary effects, which actually causes great harm to the body and mind of the beauty. Therefore, it is safer to use the old and practical whitening products.
Trick 3, sunscreen every day
Since the skin has been repaired and whitening products have been used, is it necessary to apply sunscreen? Or, in all words, sunscreen all year round!!! Because ultraviolet light is present all year round, including rainy days. If you are only sunscreen in the summer, then no wonder the skin is black!
