  • 11x Faster Acting Than Retinol

    One step closer to the active form of vitamin A, retinal is clinically proven to be faster acting on the skin than retinol (the classic form of vitamin A), with no added irritation potential.


  • Double-Layered Stabilisation System

    Our Crystal Retinal potency is optimised with a one-of-a-kind, reinforced stability system; combining crystal-encapsulation with a patent-pending carrot seed oil complex to surround and protect the fragile, yet powerful, retinal molecule over its entire life cycle in our product. This level of stability is only available at Medik8, for potent, long-lasting effectiveness.

  • Crystal Encapsulated Retinal

    Also a form of Time Release Technology, our innovative crystal encapsulation slowly breaks down on the skin to drip feed retinal into the skin overnight. This maximises skin comfort while using the powerful active.


  • Crystal Retinal Ladder

    We provide retinaldehyde in 4 different strengths, there is a Crystal Retinal for every level of vitamin A user. Most customers should start on Crystal Retinal 3 (0.03% retinal), or Crystal Retinal 1 (0.01%) if you have very sensitive skin. Then you have the option to work your way up the ladder over time to Crystal Retinal 10 (0.1%), when intensified results are desired. A fifth variant, Crystal Retinal 20 (0.2%), is available through professional-only recommendation.


  • Perfect Product Pair

    Looking to improve the appearance of radiance? Press & Glow is the everyday PHA toner that works in harmony with vitamin A to boost visible brightening results.

Use in the evening. First cleanse, then apply Crystal Retinal 1 over face and neck.

Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore, designed to be used after vitamin A.

Crystal Retinal 3 application should be phased in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen in the morning while using vitamin A.
