With such format, a very strong tingling but non-irritating sensation is expected during the first 1-2 weeks of use until the skin"s tolerance to lớn such high exposure is elevated. To ensure freshness and to prevent any oxidation, it is preferable lớn immediately use after mixing especially when mixed with water-based products. For maximum benefit from peptides and LAA individually, please alternate use between the two và avoid mixing the LAA powder with peptide-based products.

Vitamin C is an effective antioxidant that brightens the skin tone và reduces signs of aging.

Vi-ta-min C & Alpha Arbutin are less stable in formulations that contain water và use of them combined in formulations containing water is highly discouraged.Xem thêm: “Summer Time Rendering“: Siêu Phẩm Anime Hack Não Bậc Nhất 2022!

It is considered a gold standard of vi-ta-min C derivatives due khổng lồ its high stability & comfortable use, but it"s impossible to lớn achieve extremely high L-Ascorbic Acid potency with this solution. Aside from the general benefits of pure vitamin C, Ascorbyl Glucoside has been shown to offer specific skin brightening benefits.View full hàng hóa details Magnesium Ascorbyl Phosphate 10% Brightens skin toneAntioxidant support Moderate Low Smooth Lotion Combination/Dry skin AM và PM After serums, before moisturizer (Water-based cream, tube format) Magnesium Ascorbyl Phosphate (MAP) is a water-soluble derivative of vi-ta-min C.

This formula is a light cream that offers 10% pure map (very high solubilized concentration). Aside from the general benefits of pure vitamin C, map has been shown lớn offer specific skin brightening benefits, more so than other derivatives of vi-ta-min C. (Note: some brands offer "powder" formulations that offer up to 15% MAP. Such powders would offer less direct availability of bản đồ as compared to an emulsion such as this formula which has solubilized the complete 10% concentration of MAP.
