Product Details

Restore the look of skin radiance in just 7 days* with cult-favourite C-Tetra.

Utilising the antioxidant power of vitamin C and E, the hydrating serum brightens and smooths the complexion, while fighting free radicals to reduce visible signs of ageing. With an uplifting sweet orange scent, it is the perfect way to kick-start your morning skincare. The formula sinks into skin quickly, leaving behind a soft and glowing complexion.

The lightweight formula stimulates the production of collagen and elastin to help reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing skin tone. Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra has been carefully crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.

Formulated with nourishing, pampering oils combined with the anti-ageing power of vitamin C, this fast-absorbing vitamin C serum is ideal for those looking for skin rejuvenation. Perfect for those who are new to vitamin C, or are looking to upgrade from C-Tetra Cream or Daily Radiance Vitamin C.

Love it!!
Been using this for over a year after my beauty therapist recommended it to me for my acne prone skin. You only need to use a small amount and it absorbs very nicely into the skin. It makes my skin look fresh and it feels amazing

Great product
I use this daily in the morning following either the powder cleanse or aha cleanse. Great product, don’t use much (only need max 3 drops) feels like this goes further than their retinol :)
