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 10 has 0.10% encapsulated retinaldehyde and is a step up from 6 when your skin has acclimatised great for those who're keen to ramp the year-reversing impact up a gear.
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're eager to accelerate their age-reversing 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 use 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 loved it
The product was great! Saw improvements in my skin texture and pours in 3 weeks!Â
Report this reviewWONDERFUL!!!
It never irritates my skin and smoothes and refines it visible. Superior to every other product I have ever tried.
Report this reviewHoly Grail
This serum is just wow. A holy grail for me. Yes, it's so expensive, but for me as an experienced retinol user at the moment so effective. No irritations, no dry places, the skin looks smoother, although wrinkles will not disappear...
Report this reviewVery good
Great Retinal serum but pretty expensive. There are cheaper and equally effective options
Report this reviewA must
I’m 46 and I’ve bought medik8 crystal 6 and as I finished it, I went next level with this one crystal retinal 10. Perfect for this age range.
Report this reviewI love it
Serum with high concentration of retinaldehyde. Works faster and softer than regular retinol. It is a light cream, with a fine texture that is absorbed quickly, it is a great product, it has not caused me any reaction, I use it every other night, I will buy it again.
Report this reviewThe best
Truly the best retinol . Doesn’t dry out and after a few weeks I can see a differenceÂ
Report this reviewVery efficient
Serum with high concentration of retinaldehyde. Â Works faster and softer than regular retinol. Â I started using serum 0.03, then 0.06, and only a few months later I switched to this one, 0.1. Â I don't use it every day as the skin starts to dry out, I have days to restore the barrier, hydrate and nourish the skin. Â I close the serum with a cream, otherwise the skin feels tight and dry.
Report this reviewMindblowing
I've never noticed this product irritating my skin, though I definately don't recommend you go straight to this strength. It's amazing that you can get such a strong and effective product over the counter. I thought I wouldn't get the 10 strength but here I am. Definately the best retinoid out there.
