An important reason why vitamin C is highly praised by women is its whitening effect. Vitamin C can inhibit the deposition of pigment mother cells, not only effectively prevent black spots and freckles, but also discharge excess pigment, completely improve dull complexion and make skin white and shiny again.

Oral vitamin c is the most effective: vitamin c is a skin care element that is used for the past and is suitable for all seasons, and the effect is well-known. The effects range from whitening, moisturizing and anti-oxidation to improving dull skin. The doctor suggested that vitamin C is the most effective. At present, oral products usually have two forms: tablets and drinks. For the sake of taste, the content of vitamin C in beverages is quite limited. It may be less than 5% after digestion and metabolism, and the cosmetic effect is minimal. Therefore, in oral products, vitamin C in tablets is better than that in drinks.
