How to Use

Crystal Retinal 20 should only be used by those who have comfortably finished at least 2 tubes of Crystal Retinal 10 because it contains a very high retinaldehyde strength (0.2%).

“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 blankets the retinal and time-release it onto our skin gradually throughout the night to minimize any potential for irritation. We then fortified this with a patent-pending stabilization formula complex, which is unique to Medik8, to ensure the retina 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". Daniel Isaacs
