Many foods can make the skin whiter after intake, mainly referring to foods containing vitamin C and vitamin E. From the fruit side, pineapple, kiwi, dragon fruit and watermelon contain a lot of vitamin C, which can effectively play the role of antioxidant, thus playing a supplementary whitening effect. Spinach, tomatoes, swordfish, dragonfish and other foods also contain more vitamin E and vitamin C, which can effectively fight free radicals in the body and can also play an auxiliary therapeutic effect. However, the effect of using food alone for whitening is very slow. It is recommended to use topical creams or physical therapy to improve the color of the skin. You can apply topical hydroquinone cream with oral glutathione, and then use external milk light irradiation for better effect.
