Frequently Asked Questions

When should I apply Crystal Retinal?
You should apply Crystal Retinal as part of your evening skincare routine - after cleanser, toner and serums, but before your moisturiser.
Can I use Crystal Retinal every night?
As long as you build your use up gradually and start with the appropriate strength to begin with, you can use Crystal Retinal every night. For new users of Crystal Retinal, 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 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 with a moisturiser?
We do recommend applying a moisturiser after vitamin A. Our bestselling night cream, Advanced Night Restore, is specifically designed to be used following vitamin A use. It helps to boost the visible age-defying benefits of vitamin A while maintaining optimal comfort.
Can I use Crystal Retinal around my eye area?
We don't recommend using Crystal Retinal directly around the eye area due to its very delicate nature. However, that's exactly why we've created Crystal Retinal Ceramide Eye. It boasts all of the renowned age-defying power of our original Crystal Retinal, but is expertly optimised for specific use on the delicate eye area.
