Description Technical Specifications Formulation and Usage Information

L - Ascorbic Acid - Vitamin C is an organic acid with antioxidant properties. Its appearance is white to light yellow crystals or powder. It is water soluble. The L-enantiomer of ascorbic acid is commonly known as vitamin C.

Vitamin C is used in skin care products in the form of ascorbic acid. At a 10% concentration and low ph, ascorbic acid has been shown to stimulate collagen, decrease wrinkle depth and have lightening effects on pigmentation. It was thought that a minimum 10% concentration was required but newer information indicate that lower concentration (5%) may have benefit.

When Ascorbic acid is applied topically at levels ranging from 0.3-10%, the benefits are:

* Potent antioxidant, particularly in regard to protecting skin cells from UV-induced damage
* Delays tumor formation after (animal) skin is exposed to extensive UV damage
* Has a low risk of skin sensitization at concentrations up to 10% in the form of ascorbic acid
* Reduces transepidermal water loss, thus strengthening skin's barrier response
* Promotes collagen production and has the potential to thicken the dermis
* Reduces inflammation
* Ascorbic acid at levels of 5% and above has a positive effect on hyperpigmentation (though the results are not as impressive as hydroquinone, suggesting a combination of the two would be optimal)
* Improves the appearance of sun-damaged skin by strengthening skin's repair mechanisms
* Enhances the effectiveness of dermatologist-performed procedures such as peels and microdermabrasion

Vitamin C, 100% L-Ascorbic Acid, USP is a water soluble antioxidant. Very unstable in aqueous solutions, it starts to oxidize immediately, gradually producing color changes (orange/brown shift) and a reduction in activity as it converts to dehydroascorbic acid. For cosmetic use, it is best stabilized in anhydrous lipid solutions.
