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.

I have sensitive acne prone skin and this product is amazing! No irritation and definitely leaves my skin brighter and helps control breakouts!

Recommend
Have been using this for about 5 weeks and I’m happy with it so far! I followed the instructions to gradually build up to applying every night and I haven’t had any irritation or sensitivity. It is clearing up my complexion nicely and I think it will continue to do so! Not too expensive and a little goes a long way so I think it will last months.

Best retinol at this price point
Such a great product and affordable compared to other retinols out there. I have been using it for a year and it has helped keep my skin clear and soft with minimal new fine lines

The hype is real!!
really happy with how it’s going with this retinal, my first time trying one so went with a lower strength but so worth it and results are pretty fast, no irritation like most actives and just feels like a thicker moisturiser soooo pleasant

Great for sensitive skin
I have only recently started using this product and have noticed that it is very gentle on sensitive and dry skin - doesn’t irritate. Looking forward to seeing results after consistent use.

Lovely retinal
I had progressed from the first Crystal retinal and now to the number 3 and so far, it's been good and no weird breakouts. I was scared to use retinals but Medik8 never fails to deliver high performing skin care. Great product.

First time seriously incorporating retinol
First time seriously incorporating retinol. In my late thirties and I've started two weeks once a week with a moisturizer on top. Then for the next 4 weeks I'm doing twice a week and then will move to thrice a week for another month etc. So far no irritation or issues. Stopped all other actives but occasionally use vit c in the morning before SPF
