How stable is the retinol in the Enzyme-Active Retinol Serum? Does it degrade over time?Updated a year ago

Thanks to our patented containment technology, our production and bottling processes are 100% oxygen and UV-free. This way, we can maximize the longevity and potency of the fragile retinaldehyde in our Enzyme-Active Retinol Serum, for a 6 month shelf life. That said, retinaldehyde is still temperature sensitive, so we recommend storing the serum below 74°F.
