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.

Best of the best
The Crystal Retinal 6 is honestly the best retinal I’ve ever tried. The formulation is excellent and it has never irritated my skin, though I did build up tolerance by starting with a weaker retinol, then some other brand retinals and then Crystal Retinal 3 before moving to 6. It has helped a lot with my acne and noticeably softened my fine lines on the forehead and around the eyes (I’m 27, so they were just starting to show). After finishing my third bottle, I’m planning to move to a stronger version because, while the results are great, I’m hoping for even more improvement with my now occasional acne.

Fast Results Without Irritation
One of the best retinal products I’ve tried. Level 6 is perfect if your skin is already retinol-trained. Fast results without flaking.

My favorite retinal – perfect for summer
Medik8 retinals are my absolute favorite on the market. I’ve been using them for a long time, and while I normally use a higher strength now, I was really happy to get Retinal 6 in a Cult Beauty Edition. It’s perfect for summer when I prefer to lower my dosage a bit. So glad to have it back in my routine!

My favorite
I love, love this retinal! My skin is pretty sensitive but this doesn't leave my skin feeling dehydrated or red or flaky. I tried all kinds of retinol products but this is my favorite.

Nice
I enjoyed using this product! I found my skin was receptive to the retinol and I had to move up concentration fairly fast so I passed the product to a friend. Would recommend!
