Lipid vitamin C radiance serum

C-Tetra® properties
Vitamin C minimises the appearance of fine lines and wrinkles over time, while helping to visibly balance and brighten the skin tone.


Your skin contains natural antioxidants that work to defend against free radicals from the environment.
When these environmental free radicals outweigh your skin’s antioxidants, the skin can no longer protect itself.
Free radicals latch onto the defenceless skin cells, causing irreparable damage, which ultimately leads to premature skin ageing.

C-Tetra works to protect the skin from free radical damage, featuring vitamin C to boost the natural antioxidant defence levels in the skin.
Vitamin C is a key pillar of our CSA Philosophy, due to being one of the most powerful vitamins for preventing the signs of premature skin ageing.
Vitamin C also helps to stimulate collagen production, and can disrupt the overproduction of melanin to brighten the appearance of dark spots and uneven skin tone.
The result? Visibly radiant, healthier, more youthful-looking skin.

C-Tetra contains tetrahexyldecyl ascorbate, a form of vitamin C which is a stabilised modification of ascorbic acid (the purest form of vitamin C) that is gentle on the skin yet proven to deliver visible results.
Vitamin C and vitamin E work together synergistically as ‘network antioxidants’, boosting the serum’s overall antioxidant effect to keep skin protected throughout the day.
C-Tetra is based on jojoba seed oil, for lightweight nourishment and an instant glowing appearance.
The natural emollient oil slips effortlessly into the skin barrier, delivering the vitamin C benefits with ease.

Size: 8ml/ 30ml
