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
