Protocol's proprietary Oxidate Retinol™ formula was designed to stabilize the most effective (and fragile) form of non-prescription retinol on earth, often called "retinal" (with an "a"). This form, is the intermediary molecule that is created when regular retinol (vitamin a) is applied to the skin. Because of this, it's one step closer to "retinoic acid" or the form of retinol that your skin really needs.
Why is no one else doing this?
This form of retinol is extremely fragile and needs to be made and bottled in a 100% oxygen and UV-free environment. Protocol is the only lab in the US that has ensured the entire process, start to finish, never sees oxygen or the light of day.
The secret that brings it all together though, is what we call our Little Orange Ingredient Fortress:
A proprietary, clinical-grade, totally airless and UV proof bottle that's built like the space shuttle to protect our advanced and fragile ingredients. The quality of product it delivers will be apparent from the first pump.
