Discover a younger-looking complexion with Crystal Retinal 10.
Featuring retinaldehyde (retinal), a next-generation form of vitamin A which is not to be mistaken for the classic form of vitamin A, retinol. In numerous studies, retinal has been demonstrated to be more effective and 11x faster-working than retinol, without any additional irritation.[1,2,3] The hydrating overnight serum-cream visibly addresses signs of aging; improving the appearance of wrinkles, texture and tone.
Potency and optimum power is ensured through a double-layered stabilization system, which includes a crystal encapsulation that releases vitamin A gradually throughout the night, to protect the skin from becoming overwhelmed at any point. Hyaluronic acid and glycerin also feature to moisturize and hydrate skin, minimizing any dryness. The complexion is left visibly smooth and supple. Crystal Retinal is available in a series of progressive strengths. Crystal Retinal 10 (0.1% retinal) is recommended only for those who have comfortably used Crystal Retinal 6. Medik8 recommend a simple, effective skincare strategy of using vitamin C and sunscreen in the morning and vitamin A at night.
This strategy is called: CSA.

Excellent serum!
I have been thinking about trying this brand for a long time now and thanks to the VIP sale, I finally got my hands on it. The serum smells great and has really made a difference in my skin. The serum not only helps with diminishing lines and wrinkles, but it also helps prevent acne breakouts. I will definitely repurchase this product to continue to reap the benefits!

Retinal
I have used only one other retinal before this and it was in a serum form. I do have sensitive acne prone skin and it works lovely . I did not start off with other medik8 retinals and found this one non irrating following with a lotion. If you have used a lot of different skincare products but are worried this will be too drying , don't. It works very in-between my retinOl regime which is indeed drying. This retinAl is great ! 2nd time buying before leaving a review.

Excellent Product
Using for not even a full month and I can actually see the difference in my skin. I was even able to go out without makeup. Looking forward to purchasing again.

As a user of Tret, this is fun to use on the nights I don't use tret, but want to use a exfoliator
I really love this product for the service it renders. It definitely exfoliates, but without the irritation. I have read about this product for years now and finally decided to purchase it. I am glad that I did! Instead of using tretinoin, which can cause irritation with too many uses, this offers a reprieve, but still renders results!

Great product
This is my first purchase of this product, but I like it so far. My skin is acclimated to retinols, so I went straight to the 10 and am happy with it. I am still introducing it somewhat slowly just to avoid irritation and so far it’s great. Before this I was using the Skincuticals, which I really like, but wanted to see how this compares. My skin hasn’t dried out and I don’t have any irritation. It’s too soon to tell if I’ll see any results from it, but at least it’s not damaging my moisture barrier.

Best Retinol Around
I absolutely adore this retinal serum. I do not have sensitive skin, but tretonin felt harsh even with a gradual build up. I have found that at this level I get the fine line improvement I did with tretonin without the sensitivity best of both worlds! I use it every other night and have found that the tube lasts me almost 6 months which makes it very cost effective as well. I would recommend this to anyone and everyone!

So happy
I’ve been using active glycolic serum for years with great results. I decided to step up to an actual retinol. I hadn’t worked my way up but figured I could start with this considering being a consistent active glycolic user. I’m so pleased. It soaks into the skin evenly and quickly. It leaves my skin glowing before bed when I use it. I’ve noticed a difference in fine lines and I’m so glad I’ve added it to the rotation. If you haven’t used retinol or active glycolic I don’t recommend starting out with this but once you work your way up (if you need to!) you’ll definitely love it.

Holy Grail!!!
This is definitely one of my holy grail skincare staples. I do use tretonoine, but I like to have a product to rotate with that product, and the crystal retinol 10 is perfect for my line-up. Plus, I feel like my skin just feels healthier after it’s use, which I can’t always say with Tret. Will never be without it!
