Hyaluronic acid and glycerin leave skin supple and hydrated, while also supporting skin’s natural barrier.
How C-Tetra Vitamin C Radiance Cream works on your skin
Your skin needs antioxidants to defend it against free radical damage from the environment. When environmental free radicals outweigh the antioxidants present in your skin from diet and nutrtion the skin can no longer protect itself. Free radicals create irreparable damage to our cells which leads to visible premature ageing of the skin - discolouration, sagging, wrinkles & malignant cell changes
C-Tetra Cream contains tetrahexyldecyl ascorbate, a stable form of vitamin C that boosts the antioxidant defence levels in the skin. Vitamin C stimulates collagen production to reduce the appearance of fine lines and wrinkles, leaving the complexion plump, radiant and youthful. As a lipid-soluble form of vitamin C, it is able to penetrate the skin’s defensive lipid barrier with ease, delivering benefits deep within the skin.
Vitamin C and vitamin E work together synergistically as 'network antioxidants', boosting the cream’s overall antioxidant effect.
C-Tetra Cream also harnesses superior hydration power by combining hyaluronic acid and glycerin with Medik8’s signature Moisture Magnets™. These draw water from the atmosphere and from lower layers of the skin to leave the complexion supple and moisturised.
Ingredients
Tetrahexyldecyl Ascorbate
A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, while stimulating collagen production for a youthful looking.
Vitamin E
A lipid-soluble antioxidant that is naturally present in the skin. Vitamin E protects the skin from free radicals is regenerated by vitamin C for optimum power.
Hyaluronic Acid
With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion both nourished and supple.
Moisture Magnets
Medik8’s signature hydrators bind to skin cells and grab onto water to lock moisture in tight where it is needed the most.
