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).

yes!
I've been using Medik8 Crystal Retinal 6 for three years now, and honestly, I can’t imagine my nighttime routine without it. It’s super gentle but seriously effective—I noticed smoother, more even skin pretty quickly, and over time, it’s helped with fine lines and breakouts without any irritation. I love the creamy texture, which absorbs beautifully and doesn’t leave my skin greasy. This little bottle might look small, but it lasts ages, and it’s worth every drop. It’s one of those products I can’t see myself ever giving up!

Medik8 Crystal Retinal 6 is a standout product in the world of skincare, especially for those looking to incorporate retinol into their routine. This advanced retinaldehyde formula offers the benefits of retinol but with less irritation, making it suitable for those with sensitive skin. I love how lightweight the texture is—it absorbs quickly and doesn’t leave a greasy finish. With consistent use, I noticed my skin appeared smoother and more radiant, with a reduction in fine lines and uneven texture. The packaging is also impressive, featuring an airless pump that keeps the formula stable and effective. If you're looking for a powerful yet gentle anti-aging treatment, Medik8 Crystal Retinal 6 is definitely worth adding to your skincare arsenal!

Powerful but no irritation
I have sensitive skin and using retinol normally makes me suffer. But this product (retinal 6) doesn't irritate at all while my skin gets everything that retinol usually gives. Just a magic, love it! Maybe I should try retinal 10.
