Unopened, Apoterra Skincare’s products can last up to 2 years if stored in ideal conditions (cool, dry, and darkroom). Once opened, your product should be used within the time indicated on the packaging (usually 6 months). Look for the small jar symbol on your packaging (will say “6M” to indicate use 6 months once open). Alternatively, you can look up the shelf life of your product under the “Details” tab found in the product listing. The batch # on your product can be looked up to discover the date your product was made.
