Hear from the experts
“After years of research and experimentation, we cracked the retinal code in 2018 with a unique stabilisation discovery. Our reinforced stability system involves two formulation techniques. First, we protected the powerful yet fragile molecule with a crystal encapsulation that works to both blanket the retinal and time-release it onto our skin gradually throughout the night to minimise any potential for irritation. We then fortified this with a patent-pending stabilisation formula complex, which is unique to Medik8, to ensure the retinal is stabilised throughout its whole life cycle - from raw material, all the way onto our skin. This means that your Crystal Retinal remains powerful from the first application, to the very last".
