Supercharge your skin's radiance each morning with C-Tetra Luxe; clinically proven to reduce the appearance of wrinkles and hyperpigmentation in just 4 weeks.*

Featuring twice the amount of vitamin C (14%) of our original C-Tetra serum, C-Tetra Luxe is ideal for those looking for enhanced skin radiance and antioxidant protection alongside deep nourishment.

The velvety-soft serum is formulated with a stabilised (and therefore very potent) form of vitamin C called tetrahexyldecyl ascorbate (pronounced 'tetra-hexul-deckul as-CORR-bate'), which delivers proven results after just 1 use*; all with a gentle, nourishing experience for your skin.

*Proven via independent clinical study on C-Tetra Luxe conducted over 4 weeks on 36 participants

The perfect option for supercharged skin radiance plus visible line-smoothing results.

DANIEL ISAACS Chief Product Officer

C-Tetra Luxe is the pinnacle of our C-Tetra range, containing 14% tetrahexyldecyl ascorbate; double that of our original C-Tetra serum.

It also boasts an infusion of radiance-boosting antioxidants delivered in a nourishing squalane base, making it the perfect all-rounder within our vitamin C range.

We recommend this for the majority of skin types including those looking for supercharged age-defying results, as well as drier and dehydrated skin types.

C-Tetra Luxe is unique as it remains gentle on the skin despite its high concentration of vitamin C.
