Your skin is packed full of natural antioxidants that defend against free radicals from the environment. When these environmental free radicals outweigh your antioxidants, they can no longer protect the skin. Free radicals latch onto the defenceless skin cells, causing irreparable damage, which ultimately leads to premature ageing.

1. C-Tetra Eye contains tetrahexyldecyl ascorbate, a super-stable form of vitamin C that boosts the antioxidant defence levels around the delicate eye area. Ever the multi-tasker, it also stimulates collagen production to reduce the appearance of fine lines, wrinkles and crow’s feet, leaving the under-eyes youthful and awakened

2. As a lipid-soluble form of vitamin C, tetrahexyldecyl ascorbate is able to penetrate the skin’s defensive lipid barrier with ease, delivering benefits deep within the skin.

3. Vitamin C and vitamin E work synergistically as ‘network antioxidants’, boosting the serum’s overall antioxidant effect to keep skin protected throughout the day.
