Medik8 C-Tetra Advanced is a high-performance Vitamin C gel-serum formulated with 20% stabilised Tetrahexyldecyl Ascorbate to help visibly brighten uneven skin tone, smooth the appearance of fine lines and provide advanced daily antioxidant protection. Despite its high Vitamin C concentration, the lightweight formula has been developed to deliver potent brightening benefits while remaining gentle and comfortable across all skin types.
The next-generation formula combines Vitamin C with green tea-derived Phyto Exosomes and antioxidant Acetyl Zingerone to help defend the skin against environmental oxidative stress and support a more resilient-looking complexion. Hyaluronic Acid provides immediate hydration and plumping, while N-Acetyl Glucosamine helps refine visible pores, support the skin barrier and promote smoother, more even-looking skin.
With a fast-absorbing, non-greasy gel-serum texture, C-Tetra Advanced is ideal for clients wanting a more intensive Vitamin C treatment for dullness, uneven tone, visible ageing and environmental skin stress. Medik8 positions it as the 20% strength option within its C-Tetra Vitamin C range.
