25% Vita-C Serum (L-Ascorbic Acid) 100ml

25% Vita-C Serum (L-Ascorbic Acid) 100ml As stabilized vitamin C, it is about pH 3~4. The amount of vitamin maximum soluble in 100g water is 33%, and if it reaches more than 33%, the pH is low to irritate the skin. Antioxidant function Our skin requires oxygen, but from the moment when the oxygen touches the skin, it oxides and makes reactive oxygen, hazardous substances to damage normal cells. There is an antioxidant function to remove this reactive oxygen. Whitening function It is the function to make the skin transparent by reducing melanin pigment, and mitigate spots and blemishes. Function of removing sebum It is the function to prevent skin shine by inhibiting sebum secretion. Regeneration function It is the regeneration function to have an effect of making the skin smooth, elastic and improving wrinkle. Exfoliating function It is the function to remove dead skin cells occurring a lot on the dry skin and making the skin firmer. How to apply Vita C Serum to maximize the effect A vitamin C product is effective to use during daytime since it has the function to remove active oxygen. If you use it consistently, you can reduce the skin damage due to the ultraviolet light such as sunburn by increasing dermophylaxis against the ultraviolet light.If you use more than 10% of vitamin serums and sunscreen at the same time, you can get synergies. Melanin is generated under the influence of an enzyme called ‘Tyrosinase’. While Arbutin inhibits the activity of ‘Tyrosinase’, to stop production of melanin, a vitamin C has the effect of reducing the melanin pigment that have already been created, so if you use it together, whitening effect is much better. Oily skin is very difficult that a water-soluble vitamin C penetrates the sebum in the pores. Thus, it would be more effective to use after removing sebum and keratin by utilizing enzyme cleansers before using Vitamin C Serum. (Note) It is an alkaline enzyme cleanser and pH of the skin after cleansing is high to make you feel the stinging skin, so if you use it after trimmed the skin with slightly acidic toner, then you can alleviate the stinging.
