The ascorbic acid phosphate sodium salt is an active ingredient in advanced cosmetic skincare products, and it is a stable vitamin C derivative. It protects the skin, promotes its growth, and improves its appearance. Sodium ascorbyl phosphate decomposes enzymes in the skin to release active vitamin C.

Therefore, ascorbic acid phosphate sodium salt is an effective antioxidant, which protects cells from damage caused by free radicals. Ascorbyl phosphate sodium salt promotes collagen production to delay skin aging. Ascorbic acid phosphate sodium salt also acts on the melanin production process to prevent hyperpigmentation and actinic keratosis. Therefore, it makes the skin shiny.

Because of its wide range of action (the main role of ascorbyl phosphate sodium in cosmetics and skincare products is an antioxidant, whitening and removing spots, and a moisturizer), ascorbyl phosphate sodium salt can be widely used in skincare products. As an effective water-soluble antioxidant, it is stable in cosmetic formulations. For the common oil-soluble equivalent vitamin E acetate, the combination of the two is the most ideal. Oil-soluble vitamin E acetate together with the water-soluble ascorbyl phosphate sodium salt is an ideal antioxidant system in all skincare formulations, used to resist the damage of daily environmental stress to the skin.

Other very important areas of use are sunscreen formulations, anti-wrinkle products, body lotions, day creams, night creams, and whitening products. The ascorbic acid phosphate sodium salt is 0.2 to 2% for daily skincare, 0.2 to 1% for sunscreen products, and >3% for whitening products.
