Rediscover youthful skin with Medik8’s most powerful and highest strength of vitamin A Crystal Retinal 20, Medik8’s latest innovation in vitamin A. Formulated with 0.2% stabilised retinal, a powerful derivative of vitamin A with next-generation anti-ageing results. Unmatched in its age-defying power, retinaldehyde can deliver results comparable to clinical-grade vitamin A up to 11 times faster than ic forms of retinol. The ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face. Featuring hyaluronic acid, glycerin and vitamin E, it hydrates skin at every level to deliver a supple, even-toned, more youthful-looking complexion. More than that, it actively helps reduce blemish-causing bacteria to keep skin clear and balanced. In just 4 weeks, skin is noticeably younger, smoother and undeniably radiant.

Crystal Retinal 20 is perfect for those looking to upgrade their results from Crystal Retinal 10 after 3 months use or two full bottles of Crystal Retinal 10.

Available in four strengths before they introduced Crystal Retinal 20 (advanced users only, highest strength vitamin A), climbing the retinal ladder looks like this: Crystal Retinal 1 (sensitive skin or new to Vitamin A), Crystal Crystal 3 (normal strength Vitamin A), Retinal 6 (super-strength Vitamin A) and Crystal Retinal 10 (ultra-strength Vitamin A)


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 ic 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.

What makes the Medik8 Crystal Retinal so unique and powerful?


From the experts in Vitamin A, Medik8 have developed Retinal, which acts faster than ic forms of Retinol. Retinal is the closest Vitamin A molecule to Retinoic Acid. Unlike retinol, which must first be converted to retinaldehyde and then to Retinoic Acid (vitamin A’s active form) within the skin, Crystal Retinal requires just one conversion to Retinoic Acid. This formula has placed the Retinal in a Crystal Encapsulation System that works to slowly release the retinaldehyde into the skin, reducing possible irritation. 

Ideal for most skin types and for those who are used to using high strength retinol products, see below information provided in the usage tab.

0.2% Encapsulated Retinaldehyde proven to work up to 11 times faster than retinol, retinaldehyde is a revolutionary new form of vitamin A that targets fine lines and wrinkles, pigmentation and uneven skin texture.
