Medik8 C-Tetra Advanced is a high-performance vitamin C gel-serum formulated to visibly brighten, smooth and protect the skin against premature signs of ageing. Powered by a gentle yet effective 20% vitamin C derivative, the lightweight formula helps enhance radiance while supporting skin clarity and texture.

The advanced serum is enhanced with phyto exosomes, innovative messenger molecules designed to optimise the delivery of active ingredients for fast-acting results. Omni-antioxidant acetyl zingerone strengthens the formula by defending against pollution and environmental aggressors that contribute to dullness and early ageing.

With its fast-absorbing, hydrating gel texture, C-Tetra Advanced nourishes the skin barrier while delivering instant luminosity. Suitable for daily use, the serum leaves the complexion looking refreshed, smoother and visibly more radiant over time.
