Delivering gentle fine line-reducing benefits, the Medik8 Crystal Retinal 3 Serum is an advanced retinaldehyde formula that protects from the noticeable signs of ageing. Powered by 0.03% stabilised retinal, the treatment is suitable for beginners and those with sensitive skin thanks to a blend of nourishing actives and time-release encapsulation technology.
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%).

The retinal serum that I can rely on
I have sensitive skin so I used to worry about how Vitamin A skincare products might irritate. Hearing positive reviews about the Crystal Retinal formula, I decided to give it a try. Glad my skin has reacted well to it, and I will continue using it regularly to see the best results.

Best retinol!
This is by far the best retinol! I use no.3 and followed the instructions with slowly introducing in to my routine. Has transformed my skin, and I’ve had so many compliments! Pricey compared to other brands, but so worth the money as it’s the best I’ve tried! Has definitely improved the appearance of my fine lines. Will continue to purchase.

Best retinol
I use no3 and I’ve been gradually introducing it into my skincare routine at night. I’ve used it for a month now, and After 6 daily applications on week 3 I can honestly say the sun spot I have had on my cheek for a while now has visibly got lighter in colour. You can hardly see it unless you get up close! I think it’s made a difference on my frown line too. Will continue to use!
