Making skin care simple, Medik8 takes the fuss out of caring for your complexion. Powered by three key ingredients: vitamin C, vitamin A and non-negotiable SPF, the brand's signature skin care saviours are famed for their potent potions. Enter: the Crystal Retinal 6 Serum (30ml), supercharging your routine with stable retinal for bouncy and plump skin.
Speed up the line-smoothing, brightening, firming and dark spot-diminishing process with the Crystal Retinal 6 Serum (30ml).
With a unique crystal structure, this superior serum ensures stability and maximum absorption while mitigating the look of redness. With the radiance-boosting, clarifying and retexturising benefits of retinol (without the sometimes scaly side-effects), this strengthens the appearance of skin overnight, delivering 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 serum a true bathroom shelf staple.

Transparency lies at the heart of our philosophy which is why we have partnered with tech-platform – Provenance – to cut through the industry ‘noise’ and equip you with key facts that matter. A 'proof point' with a green tick means a third party has verified the accuracy of the statement whereas no green tick means that there isn't independent confirmation (yet!), but that the brand has still supplied substantiating evidence (which you can view yourself).

Best Retinol. Full Stop.
I keep on coming back to this retinol, it's the one that my skin tolerates best, and I always look like I had a good night's sleep when I wake up after using it. Love the smell, and that you can level your way up.

Got sent a sample of medik8 6 and feel in love. Has caused me to purge but that’s a good sign, doesn’t strip skin or cause any irritation

I actually feel that this retinol does something. The texture of my skin is much better whenever I’m using this. Be careful to follow the guidance so you can desensitise your skin towards it when you start using it. I began with the 3 and used 2 tubes of that over 6-9 months before going on to the 6.
