Delivering gentle fine line-reducing benefits, the Medik8 Crystal Retinal 6 Serum is an advanced retinaldehyde formula that protects from the noticeable signs of ageing. Powered by 0.06% 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%).

Holy Grail
I really rate Medik8 products. Excellent products at a decent price point and superior to more expensive products. This smooths and evens out the skin without causing irritation

Too expensive
I liked the ingredients of this product and thought it would help me with my skin texture but it did absolutely nothing! I used up the whole tube and saw no benefit. Waste of money.

Great product
I haven't used any retinol before so after some reviews decided to with no 3. Started once a week with a moisturise before and after as I have a dry skin, after a month I increased it to to 2-3 times and my skin looks like a glass! Love how it transformed my face.

Amazing
Amazing retinol once you have become more used to the less harsh ones. Really does transform your complexion and make fine lines less noticeable.

noticeable improvement
I've been using it for only three weeks now, but I can notice such great improvement -- unlike other retinol I've used in the past. I can't wait to graduate to the stronger one!

The Best!
Been using this serum now for a good year. Used 3 first then worked my way up to 6. A little goes a long way and this tube will last me months. My skin looks clearer, more even and less blotchy. At 39 years old , my skin is the best it’s ever looked. Will always repurchase this.
