How to Use

Step 1
If you're new to Crystal Retinal we recommend a patch test at least 24 hours before first use. Learn how to patch test here.

After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow Crystal Retinal Ceramide Eye, around the eye area, avoiding the eyelids, and then apply a moisturiser. We recommend Advanced Night Restore, which is specifically designed to be used after vitamin A.

Step 2
For new users of Crystal Retinal & Crystal Retinal Ceramide Eye, 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 sunscreen the next morning after using vitamin A.

We recommend using at least 1 tube of your current strength before moving up the ladder to the next strength.

Key Ingredients
Retinaldehyde

Proven to work up to 11 times faster than standard retinol[1], retinaldehyde (retinal for short) is a revolutionary form of vitamin A that effectively targets the appearance of fine lines and wrinkles, hyperpigmentation, uneven skin texture and loss of firmness - without irritation.

Hyaluronic Acid

With the ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the upper layers of the skin; leaving the complexion hydrated and visibly supple.

Vitamin E

A powerful antioxidant that provides additional antioxidant protection against the ageing effects of free radicals. It also helps to boost the power of vitamin C for optimum visible results.

Twin-Encapsulated Retinaldehyde

Proven to work up to 11 times faster than standard retinol,[1] retinaldehyde (retinal for short) is a revolutionary form of vitamin A that effectively targets the appearance of fine lines and wrinkles, discolouration, uneven skin texture and loss of firmness. Medik8's unique twin encapsulation technology produces an ultra-slow release, gradient effect of retinal in the skin to ensure equal power and gentleness on the delicate eye area.

Frequently Asked Questions

When, and how, should I apply Crystal Retinal - do I need to phase it into my routine?

Yes. You should apply Crystal Retinal as part of your evening skincare routine - after cleanser, toner and serums, but before your moisturiser. We always recommend phasing Crystal Retinal into your existing skincare regimen; using it twice a week for two weeks, then every other night for two weeks, then every night after that. You do not have to phase in when moving up a strength within the Crystal Retinal ladder (e.g. when moving from Crystal Retinal 3 to Crystal Retinal 6).

When should I use Crystal Retinal Ceramide Eye? And how much should I apply?

You should apply Crystal Retinal Ceramide Eye as part of your evening skincare routine - after cleansing, direct acids, and Crystal Retinal (for the face), but before your moisturiser. Apply a rice-sized amount per eye, per application.

Can I use Crystal Retinal & Crystal Retinal Ceramide Eye every night?

As long as you build your use up gradually and start with the appropriate strength to begin with, you can use both every night. For new users, we strongly recommend that you phase-in application to enable your skin to build up a tolerance while avoiding any potential irritation. Use twice a week for the first two weeks, every other night for the following two weeks, then every night.

Can I use Crystal Retinal or Crystal Retinal Ceramide Eye while pregnant or breastfeeding?

As a cosmetics company, we are unable to provide product advice in relation to medical conditions such as pregnancy or breastfeeding. We strongly recommend discussing the ingredients with your GP or midwife before use. We do, however, generally recommend avoiding vitamin A use while pregnant or breastfeeding, which is why we offer a plant-based vitamin A alternative - Bakuchiol Peptides.

Do I need to follow Crystal Retinal Ceramide Eye with another eye cream?

No. Crystal Retinal Ceramide Eye is expertly designed to deliver everything you need in a nighttime eye cream; age-defying results alongside deep nourishment and comfort.
