Hear from the experts

“After years of research and experimentation, we cracked the retinal code in 2018 with a unique stabilization 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 gently throughout the night. We then fortified this with a patent-pending stabilization formula complex, which is unique to Medik8, to ensure the retinal is stabilized 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. “
