DESCRIPTION

Rediscover youthful skin with Crystal Retinal 6™, Medik8’s latest innovation in vitamin A. Formulated with 0.06% stabilised retinal, a powerful derivative of vitamin A with next-generation anti-ageing results. Unmatched in its age-defying power, retinal can deliver results comparable to clinical-grade vitamin A up to 11 times faster than classic 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.2

Crystal Retinal 6 is perfect for those who are new to vitamin A or who are looking to upgrade their retinol results.

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 helps reduce the 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 6 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 6 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.

Patented Stability Matters

The more stable the molecule, the more effective it can be on the skin. Crystal Retinal offers a level of retinal stability that is only found at Medik8: our innovative stability system features our renowned crystal encapsulation and a patent-pending formula complex. The dual-layered stability system comes together to protect the retinal molecule for unmatched potency and long-lasting effectiveness.

Ladder Up

Always peak, never plateau. Ladder up your results with 5 available strengths: 1, 3, 6, 10 and 20. Most customers start on Crystal Retinal 3 (for skincare beginners) or 6 (for experienced skincare users), then over time move up to 10. 

Top tip! Crystal Retinal is also the perfect vitamin A for those wanting to target the appearance of blemishes and congestion due to retinal’s unique antibacterial action on the skin.

Retinal Results

The leader of retinal vitamin A skincare innovation, the powers of Crystal Retinal are loved by customers and skin professionals alike. The ground-breaking formula works fast to deliver the clinically proven benefits that sets Crystal Retinal above the rest.

THE SCIENCE BEHIND

“After years of research and experimentation, we cracked the retinal code in 2018 with a unique stabilisation 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 gradually throughout the night to minimise any potential for irritation. We then fortified this with a patent-pending stabilisation formula complex, which is unique to Medik8, to ensure the retinal is stabilised 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, Director of Research.

HOW TO USE

After cleansing in the evening, massage a small amount of Crystal Retinal 6 across the face, neck and and décolletage. Allow to absorb before applying your moisturiser.

Crystal Retinal 6 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. Always wear sunscreen the following morning while using this product, and for 1 week after. Consult a doctor if breastfeeding or pregnant.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase

For aggressive chewers
Color: Blue
My pup is an aggressive chewer and these keep him occupied. He keeps coming back for them. Go to replaced old chew toys. Only issue is he leaves his toys everywhere and if you step on them. They are quite sharp

Not the best for REAL CHEWERS.
Color: Blue
My dogs love to chew and these didn’t last too long. It did keep them busy and I probably will buy these again but don’t expect much resistance of yours have big dogs that love to chew toys.

These are very hard , but my puppy lives them and my large dog can't tear them up, so that is a huge plus.
