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.
