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%).

Medik8 Retinal
This stuff is stunning!! The texture is amazing, smells so nice too. It’s a good strength if you have sensitive skin too, even when you build up the days you’re using it’s not too strong.

So good!
I just love Medik8! Every product I purchase becomes a part of my everyday skincare routine. I use this every night before bed and it makes my skin look glowy and youthful and really helps with fine lines.

Love it
I was recommended this product by a friend, and I absolutely love it. It has not irritated my skin like some other retinals I have tried. My skin looks brighter and clearer, and I really feel this has helped faded some acne scars that I had. I even don’t wear foundation anymore as I feel that much happier with my skin. I have been using number 3 but will progress to number 6 next
