Ascorbyl Glucoside

Superiority:

PromaCare-AGS is natural vitamin C (ascorbic acid) stabilized with glucose. This combination allows the benefits of vitamin C to be conveniently and effectively used in cosmetic products. When creams and lotions containing PromaCare AGS are applied to the skin, an enzyme present in the skin, α-glucosidase, acts on the PromaCare-AGS to slowly release the healthful benefits of vitamin C.

PromaCare-AGS was originally developed as a quasi-drug cosmetic product in Japan to lighten the overall tone of the skin and reduce the pigmentation in age spots and freckles. Further research has shown other dramatic benefits and today PromaCare-AGS is used all over the world – not only for whitening but also for brightening dull looking skin, reversing the effects of aging, and in sunscreen products for protection.

High stability: PromaCare-AGS has glucose bound to the hydroxyl group of the second carbon (C2) of the ascorbic acid. The C2 hydroxyl group is the primary site of natural vitamin C’s beneficial activity; however, this is the site where vitamin C is degraded. The glucose protects vitamin C from high temperatures, pH, metal ions and other mechanisms of degradation.

Sustainable vitamin C activity: When products containing PromaCare-AGS are used on the skin, the action of α-glucosidase gradually releases vitamin C, providing the benefits of vitamin C effectively over a prolonged period of time. Formulation benefits: PromaCare-AGS is more soluble than natural vitamin C. It is stable over a wide range of pH condition, especially at pH 5.0 – 7.0 which is typically used for formulation of skin care products. PromaCare-AGS has been shown to be easier to formulate than other vitamin C preparations.

For brighter skin: PromaCare-AGS can function essentially as an identical manner to vitamin C, preventing pigmentation of skin by suppressing melanin synthesis in melanocytes. It also has the ability to reduce the amount of pre-existing melanin, resulting in a lighter pigmentation of the skin.

For healthy skin: PromaCare-AGS slowly releases vitamin C, which has been shown to promote the synthesis of collagen by human skin fibroblasts, thereby increasing the suppleness of the skin. PromaCare-AGS can provide these benefits over a prolonged time period.
