L-Ascorbic Acid Powder is a powerful antioxidant, and the chirally correct form of vitamin C that assists in the production of collagen. Vitamin C is the only antioxidant that is proven to stimulate the synthesis of collagen which is essential since our body's natural collagen production goes down as we age. This is the nicest, softest, powdery L-ascorbic Acid out there!

Please Keep Your Products Out of Humidity, Heat, Direct Light and in a Dark Cabinet When Possible 

Exfoliating Acid - products have a shelf life of 9-12 months. The only things we don't suggest refrigerating are the Mandelic Acid Serums or Salicylic Acid Serums, as they can crystallize in the refrigerator. If this happens, you can set the product into a hot water bath to see if the crystals will dissolve.

Additional Items That Require Refrigeration and/or Kept in the Dark

Hydrosols and Distillates - remove 1 ounce of hydrosol and add it to a separate, sterilized spray bottle and spritzer. Keep the larger bottle in the refrigerator.
Carrier and Exotic Oils - generally refrigerate all carrier oils, although some very rich oils will solidify. This is fine. All you have to do is take the oil out, warm it up at room temperature, and it should liquefy. If not, set the bottle in a hot water bath and occasionally shake the bottle, which will hopefully turn into a liquid. Some oils, like coconut cream and jojoba oil, have a super long shelf life.    

Refrigeration of The Following Ingredients is Not Necessary, But it Won't hurt

Essential Oils - essential oils are best stored in a cool, dark place.   
Co2 Extracts - these should continually be refrigerated.
Butters - we suggest refrigerating our "skincare" butters. You can remove
what you need and keep the rest in the fridge.
Clays - keep in a dry, dark place. Shelf life is at least 2 years.
Herbs All herbs <i>(whole or ground)</i> should be kept in a dark, cool, and dry location.
Herbal (liquid) Extracts are created using grain alcohol. The alcohol pulls the constituents (properties) from each herb, root, trunk, leaf, and flower. They have a shelf life of 3-5 years.
They can be stored in the refrigerator or a dark, dry place.
Other Raw Ingredients - such as Sodium PCA, Honeyquat, Oat Beta Glucan, etc., will all have different shelf lives.
