Everyone likes the folk saying that white is white, and white covers all the ugliness. There are many methods of whitening, but there is no immediate effect. First of all, we should do a good job of sun protection, because ultraviolet rays will tan and sunburn the skin. Second, we should eat more foods containing more vitamin C, such as tomatoes, oranges and kiwis. Containing more vitamin C will make the skin, because it has a strong antioxidant function, which will gradually whiten the skin. There are also some photon skin rejuvenation products that we use in medical care, combined with safe whitening masks and whitening products, to inhibit the production or desalination of melanin and gradually whiten the skin.
