Retinyl Retinoate
This encapsulated molecule is not only patented, but also exclusive to Medik8. Although a gentle form of vitamin A, retinyl retinoate has actually been proven to be 8 times more powerful than retinol when it comes to visibly smoothing, brightening and firming the skin.[1] Unlike most forms of vitamin A, it can even be used during the day due to its exceptional stability in light.
