Retinaldehyde (Retinal)
Retinal is Medik8’s revolutionary form of vitamin A, found in our cult-favourite Crystal Retinal serum. It is one conversion step closer than retinol to the active form of vitamin A (retinoic acid), that all forms of vitamin A must convert to before becoming effective on the skin. As a result, retinal is 11x faster acting on the skin than retinol[1], without any added irritation potential.
