C-Tetra is a vitamin C serum formulated to work on radiance, improve tone and start preventing the first signs of ageing effectively and with good tolerance.
It contains 7% vitamin C in an oil-soluble form, allowing it to integrate better into the skin and stay stable without oxidising easily. Its water-free formula also helps maintain the product's efficacy from first use to last, which matters with actives of this kind.
It works especially well on skin that looks dull, uneven in tone, or is starting to show the first fine lines. With continued use, the skin looks more radiant, more even and with better texture. Its jojoba oil base provides light nourishment without any greasy feel, leaving the skin softer and more comfortable.
