Frequently Asked Questions

What strength vitamin C is C-Tetra Advanced?
C-Tetra Advanced contains 20% stabilised vitamin C (tetrahexyldecyl ascorbate).

Can I use C-Tetra alongside vitamin A?

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.

Where do I layer C-Tetra Advanced in my routine?
C-Tetra Advanced should be applied in the morning, after cleansing and toning, but before moisturiser and sunscreen. If you are using multiple serums, we recommend applying them in order of thinnest to thickest in texture. Since C-Tetra Advanced is an emulsion, it should be layered on top of water and oil-based serums. This ensures your skin gets the full benefits of each product.

Can I use C-Tetra if I'm 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.
