Sodium PCA protects the skin against dryness by binding moisture to your dermis. It attracts water to the skin from the surrounding air. Added to anti-wrinkle and/or anti-oxidant creams, lotions and any product with a water phase will make a NOTICEABLE difference!!
Sodium PCA is the sodium salt of pyroglutamic acid (also known as PCA). PCA is a naturally occurring component of human skin and a part of the "natural moisturizing factors" (NMF) that maintain a healthy epidermis. Sodium PCA is very hygroscopic, attracting moisture from the air. It imparts a moist feeling to hair and skin. Sodium PCA applied to the skin is absorbed to a limited extent. It is non-comedogenic, nonirritating to the eye and skin -- even at concentrations up to 50%, and does not contribute to phototoxicity or sensitization. It is rapidly biodegradable. Soluble in water and ethanol and insoluble in oils, it is used for its powerful humectant properties in many skin and hair care products including gels, creams, lotions, shampoos, conditioners, lipsticks and foundations.

Shelf Life and Storage Information for Products and Ingredients
Finished products generally don't need to be refrigerated as they are preserved, but you can refrigerate them to extend shelf life. Shelf life is 9 - 12 months
Sample sizes do have a shorter shelf life (generally 3-6 months and items in jars can dry up quicker than this if the lid is not tightened well enough (except our vitamin C serums - use within 90 days).
Please try to keep out of high humidity or heat if possible! Store out of direct light and in dark cabinet if possible also!
Exfoliating Acid products will last 1 year.
The only thing we don't suggest refrigerating is the mandelic or salicylic acid serums as those can crystallize in the refrigerator and not go back to their normal state even if you warm them up.
Additional Items Requiring Refrigeration
Hydrosols - Take out 1/2 oz to 1 oz in a separate spray bottle from your original container and keep the larger bottle in the refrigerator!
