There are many things that can whiten skin, including food, oral medication, topical medication or certain topical treatments. Foods that can whiten skin mainly contain a lot of vitamin C and vitamin E, such as mangoes, tomatoes, deep-sea fish and other foods. Because vitamin C and vitamin E have a strong antioxidant effect, they can fight against free radicals and reduce the size of pigment cells, which can achieve whitening effect. Oral medication is recommended to choose to use reduced glutathione or cod liver oil. Reduced glutathione can effectively decompose subcutaneous pigment cells and make skin color gradually whiter. The cod liver oil contains a large amount of vitamin E. For topical medication, it is recommended to choose to use hydroquinone cream cream or vitamin E cream, which can reduce the number of skin cells to achieve a good whitening effect, and vitamin E cream can assist in whitening. The topical treatment is recommended to choose Q1064 laser, which can directly crush pigment cells and thus remove pigmentation.
