L-VC is levothyroxine C. Vitamin C can be divided into levothyroxine C and dextrovitamin C. Although dextrovitamin C has a little “restoring” and “whitening” effect, it is difficult to be absorbed by human body because the molecule is too big, while levothyroxine C can be absorbed by human skin directly, which can play a role in lightening blemishes, but it is difficult to remove blemishes completely. L-vitamin C can be absorbed directly by human skin, which can lighten the effect of pigmentation, but it is difficult to get rid of pigmentation completely. L-vitamin C can inhibit the formation of tyrosinase and reduce melanin, which in turn can play the role of inhibiting melanin formation and lighten the spots. In addition, L-vitamin C can promote the metabolism of the skin and repair the damage caused by UV rays. L-vitamin C can also promote the synthesis of collagen and has antioxidant effects, which can reduce the production of wrinkles, make the skin firm and elastic, and prevent skin aging. Usually, L-vitamin C with blemish removal effect is a high purity essence, so it is recommended to keep it in a cool place or in the refrigerator after opening the bottle to avoid deterioration. In addition, during the application of L-vitamin C to remove blemishes, you should also pay attention to avoid ultraviolet radiation in your daily life and do a good job of sun protection, and try to choose a sunscreen with a high sun protection factor. At the same time, you should pay attention to develop good eating habits and keep your mood happy, so as to reduce the formation of pigmentation.
