Vitamin C, 100% L-Ascorbic Acid, USP, Ultrafine powder is a water soluble antioxidant. Vitamin C, a potent, naturally occurring antioxidant is an important constituent of skin.  It plays a pivotal role in the prevention of dry skin and wrinkles, collegen synthesis and skin regeneration.  Ascorbate is found in all layers of the skin, but is more concentrated in the epidermis than the dermis.  However, it is readily depleted by about two thirds in cutaneous tissue stores with exposure to UV light. Biochemically, the body relies on ascorbate in the collagen biosynthetic pathway. It functions as a cofactor for two enzymes, lysyl and prolyl hydroxylases.  These are dependent on iron and Vitamin C prevents iron oxidation and thus inactivation of these hydroxylases, thereby maintaining their activity.  

Vitamin C has been shown to be effective in increasing collagen deposits and also enhancing collagen lattice contractions, implying that exogenous Vitamin C application contributes to strengthening the collagen framework and maintaining a healthy dermis.  Topical application of Vitamin C has been shown to reduce the appearance of fine lines and wrinkles. Caused by mechanisms supporting collagen production, this leads to improving the appearance of the skin.  It has further been proven to reduce the severity of sunburns and age spots.

Cutaneous levels of Vitamin C cannot be achieved well by ingestion, hence topical application is essential for preventing oxidative damage resulting from pollution, smoke and sunlight.  Its use has been shown to increase generation of stratum corneum barrier lipids and stabilize lipid profiles, in particular glucosphingolipids and ceramides.  

The difficulty for the cosmetic formulatior is that L-Ascorbic Acid is very unstable in aqueous solutions, as 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 an anhydrous lipid or silicone base, although some have reported increased stability with the use of Ferulic Acid as part of aqueous formulations. This product is an ultrafine powder, ready to use in anhydrous formulations without further grinding. 

Our L-Ascorbic Acid meets USP specifications, but it is considered a cosmetic grade material once we repackage it.

This is a cosmetic raw material and is meant for external use only in cosmetic formulations.  As with all of our materials, it should not be taken internally.

Our Customers Say...
The day I realized that topical vitamin C was causing my acne was the beginning of a long journey for me. Vitamin C is present is just about every kind of makeup and every face cream available on the market. LotionCrafters, with their amazing choice of products, and their detailed information has allowed me to create my own vitamin-c-free formulations, and have healthy skin once again.
Virginia Berthy

Absolutely the best supplier of raw ingredients all around; not least because of the exceptional customer service and freely-shared knowledge of the owner, Jen. She was obviously born to do this, and I'm thankful for that pretty much every time I place and order or contact her with a question (frequently, in other words). Great, informative website too, and competitive prices. This is always the first site I visit when ordering.
Kirsten, (Virga Botanicals)

My products are always packaged well and arrive very quickly! Nice products too.
SunnyD

My computer chat group of soapmakers began the year after Jen began her supplier career
"Lotioncrafter". We began when only a handful of folks were both selling supplies and only a few were actually making lotion and soap at home. The industry has boomed and it's a testimonial to see Jen's supply business still at the top of the supplier list! So many have come and gone. That is because both her supplies and her technical and customer support is superior to all the rest!
Thank you!
