Discover the difference this advanced formula can make to your skin with Medik8 Crystal Retinal 6, available from The Skin Clinic Direct.

This powerful overnight serum is the new generation of anti-ageing skincare, with results up to 11 times faster than classic retinol.

The revolutionary Vitamin A derivative works quickly to resurface and soften your skin for a smooth and even complexion in a matter of weeks.

What are the benefits of Medik8 Crystal Retinal 6 for my skin?

Formulated with 0.06% Retinaldehyde, this product increases cell turnover to rebuild collagen, creating firmer and brighter skin.

The natural anti-bacterial properties of Retinaldehyde also defend the skin against bacteria to prevent blemishes and breakouts.

When applied regularly, super-strength Medik8 Crystal Retinal 6 boosts hydration and protection at every level, targeting lines and wrinkles for visibly smoother skin.

It essentially triggers cellular regeneration to combat the signs of premature skin ageing and keeps your new skin moisturised and clear.

How does Medik8 Crystal Retinal 6 work?

The substance that activates these beneficial changes in the skin is called retinoic acid, and to get there from the retinol form of Vitamin A, it first has to convert to retinaldehyde and then convert again to retinoic acid.

Clinical-grade Medik8 Crystal Retinal 6 skips that first step by introducing stabilised retinaldehyde into the formula, ensuring faster results with only one conversion needed to produce retinoic acid.

Medik8 has carefully crafted a complex crystal structure that breaks down slowly when applied to the skin, ensuring maximum absorption with minimal irritation.

Additional ingredients like hyaluronic acid and Vitamin E work to eradicate pollutants and retain moisture to fortify the retextured skin.

Important information about Medik8 Crystal Retinal 6

Crystal Retinal is a potent product that comes in five different concentrations as part of Medik8’s Crystal Retinal Ladder.

Before using Medik8 Crystal Retinal 6, you should have previously used Crystal Retinal 1 and Crystal Retinal 3.

Starting with Crystal Retinal 1, you should use the product for 3 months or get through 2 full tubes before moving up the ladder to the next strength, doing the same with Crystal Retinal 3 before moving on to Crystal Retinal 6.

This is necessary to allow your skin to acclimatise to the Retinaldehyde over time, as using too much too soon can have the reverse effect of damaging your skin.

Please conduct a test on a small patch of skin before applying the product to the entire face.

Do not use Medik8 Crystal Retinal 6 if you are pregnant or breastfeeding.

How to Apply


Crystal Retinal is a Vitamin A product designed for use as an overnight serum, in conjunction with applying a Vitamin C product in the morning and wearing a sun protection cream during the day.

If you’re ready to step up from level 3 to level 6, apply Medik8 Crystal Retinal 6 in the same way:

1) In the evening, thoroughly cleanse and dry your face before you go to bed.

2) Apply a small amount of Crystal Retinal 6 to your face.

3) Gently spread the product across the face and massage it into the skin down to the neck.

4) Allow the serum a few minutes to absorb before applying your regular night moisturiser.

Crystal Retinal products should be phased in gradually, so start by applying Crystal Retinal 6 one or two evenings a week.

You should graduate to using it every other night for a few weeks before working up to applying it every night.

Remember to always wear sunscreen in the day when you’ve been using Retinal at night, as your retextured skin will be more sensitive to the sun.

The slow-release formula makes this product suitable even for sensitive skin, but if irritation does occur at this level, then return to using Crystal Retinal 3.
