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%).

Low cost brand
For a lower cost brand of retinal this is a good product. My skin is visibly line reduced and it works super fast.

So far so good
I purchased this after hearing so many good things about it. I've never used a retinal before but went straight in at number 3. I have combination/ oily skin which can sometimes be sensitive and so far I've had no irritation at all. I've been applying it to clean dry skin in the evening three times a week followed by a moisturiser. It goes on smoothly and makes my skin feel lovely. I'm yet to see any noticeable results as its early days but looking forward to seeing if it makes a difference to my skin.

Quick results!
I’ve used this 3 times so far, leaving about 3 days between each use. The weathers been very hot and sunny so I was worried that my skin would be extra sensitive, but I do make sure to wear spf every day even if I’m indoors. The results have been unreal so far! I’m 28 and I still get hormonal acne and suffered really badly when I was a teen which has left me with lots of scars. My skin has always been very oily, and blackhead are my worst enemy… but my skin hasn’t been this clear and soft in a longgg time! I read that your skin can purge, but so far I’ve been okay and I’m really excited to see the results after a few months

Great retinal
This feels really gentle and soothing to use. Having started on the Medik8 Crystal Retinal 1, I’ve had no problems transitioning straight up and think I’m already seeing a difference between using this slightly increased strength formulation. I love the smell too, it feels really luxurious on my skin. Doesn’t dry my skin out and and I’ve had no reactions (I have oily/combination skin with mild rosacea).
