Medik8s mission is simple - beautiful skin for life - which is why they consistently harness new, youth-boosting breakthroughs to keep your skin stronger for longer with three key technologies: vitamin C, sunscreen and vitamin A. High-end formulations at purse-friendly prices, this attainable range means you dont need to choose between pounds and performance: the CSA method (C in the morning, followed by sunscreen then vitamin A in the evening) makes beautiful skin aber easy simplifying your daily regime while fast-tracking your path to a healthy complexion. Whats more, the brand is committed to making sustainable changes from ethical sourcing to minimal waste so your beauty routine is as clean as your conscience.
With four strengths to suit your skins needs (and its tolerance!), Medik8s Crystal Retinal will super-charge your ritual with stable retinaldehyde to stimulate your cells to manufacture precious collagen which bolsters skins resilience and density. Level 3 stars 0.03% encapsulated retinaldehyde and is great for beginners who're dipping their face in the retinol water
Retinoic acid is the form of retinol your skin can utilise (currently only available via prescription because of its potency) however, cells convert retinol (vitamin A) into retinaldehyde then retinoic acid with remarkable results its just that they take a bit longer. Thus, by skipping a step in the conversion process and harnessing encapsulated retinaldehyde a revolutionary new form of vitamin A Medik8 speed up the line-smoothing, brightening, firming and dark spot-diminishing process with tangible changes in four weeks of use. With a unique crystal structure that is readily metabolised by enzymes when applied, Crystal Retinal ensures stability and maximum absorption while mitigating risk of irritation. With the radiance-boosting, clarifying and retexturising benefits of retinol (without the scaly side-effects), this fortifies skin overnight and delivers a visible difference 11 times faster than retinol. The addition of plumping and moisture-retaining hyaluronic acid and glycerin, alongside antioxidant vitamin E makes this perfect for those who are keen to embark on their retinol journey.
After cleansing in the evening, massage a small amount of Crystal Retinal across the face, neck and daccolletage. Allow to absorb before applying your moisturiser.
Crystal Retinal application should be phased in gradually, and only in the evening. Use twice a week for the first two weeks, every other night for the next two weeks, then every night. Always wear sunscreen the following morning while using this product, and for one week after.

Love it
My first retinal. I love how it evens out my skin tone, it just makes my skin look better and prettier in the morning. It does not help with acne! I personally found it weak for me, there was no reaction, although I used it often from the beginning.

Highly recommend
I haven’t used retinols in a few years and this is such a good product to get back into it. It’s not too harsh and I could see a difference with my hormonal acne straight away, the anti aging benefits are an added bonus!

The best retinal in the market ❤️
Medik8 CRYSTAL RETINAL 3 is a skincare game-changer. Its gentle retinol formula transformed my skin, reducing fine lines and boosting radiance. What sets it apart is the Crystal Retinal technology, ensuring gradual, irritation-free results. The packaging is practical too. A must-try for all skincare enthusiasts!

Love It!
I am already on my second bottle, i love it! It's very lightweight, but it doesn't dry your skin (i apply it on clean dry skin and i don't use any other moisturiser on top), and i wake up with a rested plump skin.

Amazing
This serum has really changed my skin texture, its much more even (eliminated the small bumps) and softer. On retinal 6 now!

Best retinoid range
This is best retinoid range of products for me. Strength 3 is great for beginners, I bought it as a present. For myself I tried max strength 10 and is really great.

Amazing product
I like use it in combination to Advanced night repair cream from Medic 8. Works realy good together. Decrease some light darck points and little wrinkles. I have normal and fairly thick skin and I decided to start with 3. But after I tried 10, it doesn’t irritate me either, but I can’t say that it works much better than 3.

The best
I struggle a lot with retinoids, but this product is simply the best! Gentle but yet effective, I definitely saw my skin getting smoother and smoother over time. Moreover, you really need a tiny amount, so it lasts forever. I only use retinoids/retinol during the winter, and just one bottle was sufficient. It's pricy, true, but it's worth it. I'm thinking about trying the crystal retinal 6 next time.
