Restore the skin’s youthful look with the Medik8 Crystal Retinal 6, a hydrating serum made with 0.10% encapsulated retinaldehyde to help deliver anti-ageing results.
Medik8 Crystal Retinal 10 utilises a potent formula of skin-loving actives that release gradually to avoid irritation. At the heart of the complex is 0.10% encapsulated retinaldehyde, an innovative version of vitamin A that works 11 times faster than retinol to target the look of pigmentation, lines and wrinkles.
The retinaldehyde is enhanced by the addition of vitamin E, an antioxidant that helps protect the skin from free radicals. The serum is infused with hyaluronic acid and glycerine for overnight hydration to help the skin awaken feeling nourished and supple.

The best of retinols
I won't stop praising Crystal. I started with medium version 6. This version of Crystal did not disappoint me at all. I like the effectiveness and softness of this serum. It doesn't cause irritation, dryness or redness, but it does require follow-up moisturizing. As well as after Crystal 6, I apply a cream with ceramides.

I really like this
I really like this. I had previously used Crystal Retinal 3, but for someone who also uses tretinoin, it did not do much. So i skipped the 6 and got a 10. I do notice with this my fine lines are less visible. It does take some time for you to start seeing the results, but I do notice my fine line being less visible, my skin is more plumped and I see difference in my skin texture. Would highly recommend!
Best Use: Wrinkles, Fine Lines, Uneven Skin Texture

It just makes sense !!
I’m an experienced retinol user and moved onto this after I felt like I wasn’t getting the results I wanted from another brand. It doesn’t dry your skin out or give you that flaky retinoid skin. I feel so glowy now and it’s definitely reduced my acne scarring to almost none!

My new fav Retinol
I was using Drunk Elephants retinol for the longest time and a friend gifted me this cream as I was complaining I wasn't seeing the results I used to with DE. I basically needed a stronger retinol. I have now been using this for 8 weeks and I love it!! The feeling when applying is soothing yet light, it doesn't dry my skin and I am seeing the benefits. I would def reccomend to anyone who's skin is in need of a strong retinol.

Lovely Product
Just ordered my second bottle. Really enjoyed this product. I use four times a week in the evenings and have noticed an overall improvement in my skin including diminished pigmentation and dark marks and even the wrinkles on my forehead and around my mouth appear less obvious. I found the product easy to use with no irritation to my skin. My face always looks glowy and rejuvenated the morning after using.
Best Use: Anti-Aging
