DESCRIPTION

Formulated with 0.1% 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 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 andvitamin 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

Reducing the appearance of fine lines in just 4 weeks,3 Crystal Retinal 10 visibly plumps and refines the skin for a more youthful looking complexion. The innovative formula has all the anti-ageing, radiance-boosting and clarifying benefits of retinol, plus the same low irritation. But armed with high-performance retinaldehyde, it is able to provide visible results up to 11 times faster. The naturally peach-coloured serum-cream sinks effortlessly into skin to nurture and smooth the complexion. Featuring a natural comforting aroma of vanilla and tonka bean, it leaves skin strengthened, hydrated and ready for overnight rejuvenation.

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 10 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 10 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 10 across the face, neck and and décolletage. Allow to absorb before applying your moisturiser.

Crystal Retinal 10 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.

Great substance; lousy writing.
Format: Kindle
Reviewing this book is not an easy task. Previously I had very limited knowledge of this period of history. With no background, I found the subject spellbinding. The author has done a wonderful job of gathering, and reconciling, ancient sources of mixed reliability. But, in undertaking that task, the text becomes repetitive, difficult to follow and frankly just plain boring. In addition, the writing style and format detracts substantially from the pleasure of learning from the substance. Everything from run-on sentences with mixed subjects to unclear antecedents, to character confusion because of similarity of names and the author's expectation that one can remember which player is on stage at any given moment. My main criticism of the book is that the downsides could have been avoided by application of the skills of a decent editor who instinctively would have addressed and corrected the confusion in presentation that made it a very difficult read. I hope that a cleaned up edition is prepared and the book released again; I think the effort would be worth the result.

This composer has written an amazing piece of music.
I like how an ancient setting coupled with a new style of composing can produce something so very special. The composer is very creative, and the artists do his work justice. A serious-minded classisist will love this DVD.

Good content but not great for Kindle
Format: Kindle
Solid writing with not-many editorial issues (rare these days so overall, that’s a thumbs up). Lots of links that take you to other pages, but in both a kindle and the kindle iOS app, you won’t find a way back to the original page, which is infuriating. Not super happy with the black-and-white photos, either.

More than a bit dry, but worth reading
Format: Hardcover
Nice, fresh look at Carthage. It can be a touch dry and in some places hard to read but worth the effort. Most histories of Carthage start and stop with the Punic Wars, this is a much more expansive look at Carthaginian and Phoenician history. Given its scope I would have expected a much larger book but Carthage was destroyed and along with it, so too was its history.
