Medik8 C-Tetra Advanced Vitamin C Serum 30ml

The Medik8 C-Tetra Advanced is a vitamin C antioxidant serum designed to address visible signs of ageing and environmental skin damage. Presented in a 30ml bottle, this lightweight gel-serum formulation aims to deliver brightening and smoothing benefits while protecting the skin from daily aggressors. Its primary function is to improve skin radiance and texture through a combination of potent actives and advanced delivery technology. The formula centres on a 20% concentration of vitamin C, specifically formulated to be gentle yet effective. This is supported by phyto exosomes, which are plant-derived messenger molecules intended to optimise the delivery and absorption of the active ingredients. The serum also contains acetyl zingerone, described as an omni-antioxidant that provides defence against pollution and other environmental factors that can dull the complexion. The consistency is noted for being hydrating and fast-absorbing, working to nourish the skin barrier with each application without causing disruption. This serum is best suited for individuals looking to incorporate a targeted antioxidant treatment into their daily skincare routine, particularly those concerned with loss of radiance, fine lines, and the effects of pollution. Its clinical testing, conducted over four weeks on 32 participants, claims visible improvements in brightness, wrinkle appearance, and skin smoothness within seven days of use. The product fits into a regimen typically applied after cleansing and before moisturising, offering a layer of preventative protection and corrective care.
