Frequently Asked Questions

Can I use Pure C15 while pregnant or 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.
What's the difference between Pure C15 and C-Tetra Luxe?
Pure C15 is formulated with 15% L-ascorbic acid (making it the ideal choice for those wanting a pure vitamin C formula) while C-Tetra Luxe is formulated with 14% tetrahexyldecyl ascorbate plus nourishing actives for potent antioxidant power alongside deep skin comfort.
When and how should I apply Pure C15?
You should apply Pure C15 in the morning after cleansing. Massage 5 drops across the face, neck and décolletage. Follow with a moisturiser and sunscreen. We recommend Advanced Day Ultimate Protect - your daily moisturiser and SPF 50+ sunscreen in one.
Can I use Pure C15 alongside Crystal Retinal?
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.
