How to Use

Step 1
If you're new to Crystal Retinal or Advanced Night Restore, 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.

Step 2
For new users of Crystal Retinal, phase in application 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.

Step 3
Once Crystal Retinal is fully absorbed, apply Advanced Night Restore to face, neck and décolletage using upward strokes.

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.

Multi-Ceramide Complex (with essential lipids)

A unique combination of ceramides (alongside phytosterol and fatty acids) which mimic your skin’s natural lipid barrier to intensely restore and nourish.

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).

Should Advanced Night Restore be used in the morning or evening?
Advanced Night Restore should be used in the evening, as the last step of your nighttime routine. This is because it is designed to work in synergy with your skin's natural overnight repair processes.
Can I use Crystal Retinal every night?
As long as you build up gradually and start with the appropriate strength, you can use Crystal Retinal every night. For new users, we strongly recommend that you phase in application to enable your skin to build a tolerance while avoiding any potential irritation. Use twice a week for the first 2 weeks, every other night for the following 2 weeks, then every night.
Can I use Crystal Retinal 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.

Can I use Advanced Night Restore while pregnant / breastfeeding?
As a cosmetics company, we are unable to provide product advice in relation to medical conditions such as pregnancy. We would recommend discussing the ingredients with your GP or midwife before use. As general guidance, this product does not contain any ingredients which we would recommend to avoid during pregnancy, unless advised by your doctor.
Why has Advanced Night Restore been formulated to work alongside vitamin A?
Due to rapid cell turnover promoted by vitamin A use, sometimes skin can feel a little drier than usual. This makes Advanced Night Restore the perfect complement to vitamin A use - ensuring you get all the power of the vitamin A alongside the most comforting and nourishing moisturisation experience.
