C-Tetra® Luxe (Travel Size)
Lipid 14% Vitamin C Enhanced Radiance Serum

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.* It also works to boost visible radiance while supporting the skin barrier. 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 32 participants
