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.

Spring Water hydrating, natural solvent

Phospholipid (liposome/soy based) penetration enhancer, which allows the beneficial nutrients into the skin barrier, hydrating
Cromoist (hydrolyzed oats) softens the skin and creates a film forming a barrier for the skin to retain moisture
Glutathione it is the major antioxidant produced by the body. Antioxidants such as vitamins C and E cannot be made by your body and in fact, could not work properly if glutathione were not present. Our immune systems depend on a steady supply of glutathione. Without it, our immune defenses become weakened. It is important in detoxifying many substances including heavy metals, breakdown products of cigarettes and automobile exhaust, many cancer-causing agents, and a multitude of pollutants and toxins we encounter on a daily basis. The major source of energy produced in our cells is derived from tiny structures called mitochondria. These mitochondria would literally burn up without the presence of glutathione.
