Frequently Asked Questions

Can I use Intelligent Retinol 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.

When and how should I apply Intelligent Retinol?
Intelligent Retinol should only be applied as part of your evening regime. After cleansing in the evening, massage 4 drops evenly across face, neck and décolletage. Follow with a moisturiser.
Can I use Intelligent Retinol Eye TR alongside vitamin C formulas?
Absolutely. In fact we recommend it as part of our pioneering CSA Philosophy which champions vitamin C plus sunscreen by day, vitamin A by night as the simple secret to glowing, youthful-looking skin.
What's the difference between Intelligent Retinol and Crystal Retinal?

The main difference is that Intelligent Retinol is formulated with retinOL, whereas Crystal Retinal is formulated with next-generation retinAL. While retinol is a great option for vitamin A beginners, retinal is proven to work up to 11x faster than standard retinol in delivering visible age-defying results.*
