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.

How It Works
Clinical-grade vitamin A, otherwise known as retinoic acid, is an exceptionally powerful skincare ingredient for youthful-looking skin. Highly potent and wildy efficacious, it is able to trigger cellular regeneration and collagen production to fight all visible signs of ageing. Retinoic acid is only available with a prescription, but vitamin A is available over the counter in the form of retinol skincare products.
Retinol has similar effects to retinoic acid, however it must first be converted to retinaldehyde and then to retinoic acid to be used by the skin. Crafted with retinaldehyde,
Crystal Retinal requires just one conversion to retinoic acid. This means that it is able to produce results comparable to retinoic acid up to 11 times faster than classic forms of retinol. The advanced active is carefully encapsulated in a crystal structure that is broken down by the skin’s natural enzymes when topically applied. This ensures maximum stability and absorption while allowing the vitamin A active to be released gradually into the skin while you sleep for minimal irritation.

Combined with hydrating hyaluronic acid and skin-soothing vitamin E, Crystal Retinal targets fine lines and wrinkles for smooth and visibly youthful skin. Unlike other forms of vitamin A, retinaldehyde boasts direct, powerful antibacterial properties. This allows it to target acne-causing bacteria; promoting a healthy, visibly clear complexion.
How To Use
Use in the evening. First cleanse, then apply Crystal Retinal 3 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.
Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
