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.

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).

Bought this after using retinal 3 for a while to let my skin get used to it. This definitely packs more of a punch! No ‘retinal uglies’ phase yet as experienced with similar products , hopefully I’ve avoided it altogether. Results from first week. Worth every penny.

Holy grail for sure
I haven’t worked my way up to tret yet but my skin gets on so we’ll with CR6. I really missed it while I was pregnant. The results aren’t instantaneous but over time you can really tell it’s doing its thing.

Essential
I started with the retinal 3 and have progressed to the 6. This really makes a difference to my skin. I didn't realise how much until I skipped it for a week and the texture of my skin was awful. Will be a staple in my night routine.

Go to retinol
I started with cr3. Now continuously using cr6. My skin is happy with it. No drying or peeling whatsoever. I use it every other night. Texture is nice, no sticky at all, sinks in immediately.

Can’t recommend enough
Before purchasing this I had been very loyal to my drunk elephant retinal, but this definitely has my heart. I use retinal regularly so this might be why I didn’t experience any irritation with this. I noticed a difference from the first time I used it and 6 months on I still see the difference when I use this product. Also works really nicely with the medikate retinal eye cream

Amazing
I can see an improvement in my skin texture. Before I used to have a lot of beakouts and a lot of acnees. It feels cleaner and healthier now although I've been using it 3-4 times per week.

Improves skin texture
This is a good cream. However it causes small breakouts near my nose and as such I use it in targeted areas such as my forehead. It has reduced the wrinkle between my eyebrows. However, need to keep using it every day to see results.

Has reduced hyperpigmentation, fine spots and smothed skin overall.
