Delivering gentle fine line-reducing benefits, the Medik8 Crystal Retinal 10 Serum is an advanced retinaldehyde formula that protects from the noticeable signs of ageing. Powered by 0.1% stabilised retinal that's released via encapsulation technology, the treatment is best suited to experienced users of the active.
The fast-acting form of vitamin A is known for its skin-smoothing effect and potent renewing properties. Paired with hyaluronic acid, glycerin and vitamin E, the serum diminishes the look of uneven texture, dullness and discolouration to promote the illusion of enhanced elasticity and bounce. Dermatologist recommended, the innovative Crystal Retinal collection features a unique ladder of five progressive strengths (0.01 - 0.2%) to ensure optimal results at every level of your retinaldehyde journey.
- 97% felt their skin had a more youthful appearance*
- 20% reduction in the appearance of wrinkles*
- 20% reduction in visible pigmentation*
- 11% increase in skin firmness*
- 100% felt Crystal Retinal was gentle on their skin*
*Proven via independent clinical study on one tube of Crystal Retinal 6. Tested on 33 participants over 12 weeks.
Step 1: After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser.
Step 2: For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.
NOTE: Ladder up your visible age-defying results over time with Crystal Retinal's 5 progressive strengths (0.01% - 0.1% retinaldehyde). For those with very sensitive skin, we recommend starting with Crystal Retinal 1 (0.01%). However, most Crystal Retinal and vitamin A beginners start on Crystal Retinal 3 (0.03%). If you're an experienced vitamin A user already, start at Crystal Retinal 6 (0.06%) before working your way up to Crystal Retinal 10 (0.1%).

Medik8 crystal retinal 10
I really like this product and product range. I began slowly with the retinol 3tr and as my sensitive skin tolerated it well I changed to the 6tr and after a period of 9 months now use the Crystal Retinal. My skin looks firmer and and my complection is perfect. I have purchased a number of products from LookFantastic over the year and feel so glad to have found such a great company to deal with. From order to delivery, quality and customer service I am 100% satisfied.

Great product!
I strongly recoment the Cristal retinals from Medik 8. They are gentle, not irirtating, but very efective. The product is very nice as feeling and doen't require night cream in most cases. If your skin feels dry, then add night cream. I upped gradualy 3, 6, and then 10. Aply it even around the eyes and no rirtation. Go girls, this is gold standart for anti aging.

Best over the counter retinol
I worked my way up to using the crystal retinol 10, after having used the crystal retinol 3 and then 6, and I am so pleased with it. Medik8 crystal retinols are simply the best there is- they are so gentle but extremely effective. I have not had and flaking or irritation at all, just more even textured, glowing skin over time. I’m really happy with this product and would definitely recommend it (after using the more gentle crystal retinols first!)

Fab product
This is amazing. At first my skin broke out, but once it was used to it I got some great results. My skin is much brighter and I’m already on my second bottle. Highly recommend.
