DESCRIPTION

Retinaldehyde is the star of Crystal Retinal; a next-generation form of vitamin A that is proven to deliver results up to 11x faster than retinol[1]. Yes, this is retinAL, faster-acting than retinOL, the classic form of vitamin A.

Anti Ageing

Rediscover youthful skin with Crystal Retinal 1™, Medik8’s latest innovation in vitamin A. Formulated with 0.01% 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 1 is the entry level retinal serum for those who have sensitive skin or seek a low strength but highly effective vitamin A serum in their routine.

KEY BENEFITS

Supercharge the results of your night-time regime. Reducing the appearance of fine lines in just 4 weeks,3 Crystal Retinal 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 retinal, it is able to provide visible results up to 11x 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 1 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 1 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

Works great on bullet coffee!!
Color: Lux Alpha Black, Size: Rechargeable Z1 Motor Max
I am really pleased with this frother! Frothers I have used in the past didn’t mix my decaf coffee, 2% milk, and MCT oil as thoroughly as I like (oil and coffee separated). This frother blends everything AND I get a nice layer of frothy milk on top!!! Charge lasts a long and the froth can be submerged all the way up to the button!!!

Compact, lightweight, and useful milk frother.
I ordered the Electric Handheld Milk Frother in the Starlight Black color. I don’t drink coffee, let alone fancy coffees where I would normally need a milk frother, so I bought this for one reason and one reason only: scrambled eggs. I make a ton of scrambled eggs. Now, I can whisk eggs by hand just as well as the next person, and I’m not entirely convinced a frother whips them better than I can, but regular whisks take up a ton of room in my drawers and this does not. I really just wanted something compact that could whip my eggs into a nice frothy consistency without taking up much space. Even better, this one looks nice enough to just leave sitting on the counter where I can grab it easily. I will note that although I can hand whisk easily enough, there are many people who cannot due to arthritis or other issues, and this whisk is a brilliant tool for them. If you actually want to use a frother for other things, this one does perform very well. It has three speeds and comes with three different attachments: a spring whisk for latte and cappuccino foam, a balloon whisk for eggs and cream, and a hook whisk for blending protein powders or mixes without lumps. I actually ended up using the hook whisk while making pot roast. I mixed the seasoning packet with water using this frother and it blended everything perfectly with no lumps at all. The frother itself is lightweight, pretty quiet, and very easy to clean. The attachments detach easily and just need a quick rinse under soapy water. It also comes with a magnetic wireless charging dock that uses the included USB-C cable. The docking connection is simple and secure, and charging has been completely hassle-free so far. The LED display shows battery levels at 25%, 50%, 75%, and 100%, which is useful for knowing when it needs to be charged. Overall, it’s a simple, convenient kitchen gadget that does exactly what I wanted it to do and I am quite satisfied with it.

Works great and easy to use
Kitchen gadgets have a way of accumulating. You buy them with good intentions, use them twice, and then they live in a drawer forever. This milk frother is not that. It's one of those rare small appliances that earns its spot on the counter every single morning. The wireless charging is the feature that sets this apart from every other handheld frother on the market. No fumbling with a charging cable, no little dock that takes up extra space — just set it down and it charges. It sounds like a small thing until you've used it, and then it feels like the obvious way every handheld kitchen tool should work. The fact that it charges quickly means you're never waiting around or reaching for it only to find it dead. Three speed settings give you real control over the result. Low for gentle mixing, high for a proper thick foam that holds up in a latte or cappuccino the way it should. The stainless steel whisk feels durable and substantial, not like something that's going to bend or corrode after a few months of daily use. The whole thing is well-made in a way you notice immediately, solid, balanced, and built to last. The Starlight Black finish looks sharp, too. It's sleek enough to leave out without cluttering your kitchen aesthetic, which matters when you're using something every day. If you make lattes or cappuccinos at home and you're still shaking a jar of milk or settling for flat foam, this is the upgrade you didn't know you needed. Easy to use, quick to charge, and genuinely well crafted.

Three Speeds, Two Charge Options, Three Interchangeable Whisk Heads
I like this electric milk frother—it enables you to simulate café-style drinks at home. Three speed settings make it easy to switch from mixing matcha to whipping up thick, creamy foam for lattes. It also comes with three interchangeable whisk heads, so it is not just for coffee—I made French Toast with it the 1st time out. It can handle other tasks, like blending eggs, cream, and even protein shakes. The LED battery level display is up front right below the power button and shows state of charge as well as increasing battery level during the charging cycle. The dual charging options—either the magnetic charge stand or the USB-C charge port on the side of the motor—make it convenient for home or for travel. Best of all, all the detachable whisk heads clean up fast, so using it daily does not feel like a chore. I will say that I prefer a momentary one-speed switch instead of cycling the speeds (9K RPM, 11K RPM & 13K RPM) with the power switch. It spins up very fast and to shut it off you have to keep pressing the power button through faster speeds and before you can shut it off, it overflows the cup sometimes. You can also long press the power button to turn it off, but it usually takes too long and still overflows—I wish it was more controllable. I found that the corkscrew-hook head is the best of the three to tame that effect.

Good companion to a coffee setup
This electric frother is a great companion to have in a kitchen/coffee setup and I've been using it to mix my morning coffee. The frother includes a stand which serves as the charging base and multiple attachments (likely won't really see too much use realistically). My only downside is that the stand situation is a bit lackluster as the wireless charging feature requires you to line up the two pins at the top to the stand and balance the frother. Alternatively the frother also has a USB C charging port (sadly not USB C compliant as it can't be charged via USB c to c). The frother itself cycles between different levels of speed when you press the button and it is pretty strong; being able to very easily swirl and mix large amounts of coffee leaving mine nice and frothy. I've also been using this to mix drink powder mixes to great effectiveness. The other attatchments don't really hold too much value to me (other than maybe the whisk for eggs) but is nice to have other options included. Overall this frother is a massive step up over me using a spoon to stir my coffee.
