C-Tetra Advanced is Medik8’s most advanced brightening and age-defence vitamin C day serum, containing a high 20 percent concentration of ultra-gentle stabilised vitamin C (THD ascorbate).
Cleverly, despite its strength, it stays kind to the skin, so it suits those who want a high-strength vitamin C but have sensitive skin.
Its creamy gel formula absorbs quickly and is boosted by super antioxidant acetyl zingerone and phyto exosomes, which help soothe and support the skin barrier while delivering fast-acting brightening.
Used each morning, it helps brighten the look of uneven tone and the appearance of pigmentation, firm and smooth the skin, and defend against environmental stressors, for a visibly radiant, more youthful-looking complexion.
Apply after cleansing, before moisturiser, and always follow with SPF.
