Medik8 C-Tetra Advanced 20% Vitamin C Gel-Serum 30ml is a high-performance vitamin C gel-serum designed to boost radiance, smooth the skin’s appearance, reduce wrinkles, and provide daily antioxidant support. Formulated with stabilized 20% vitamin C (Tetrahexyldecyl Ascorbate), it delivers a potent yet gentle brightening action while helping defend the skin from signs of aging caused by free radicals and environmental exposure. This optimized form of vitamin C is known for its stability, ensuring that the formula maintains its effectiveness from the first application to the last. The formula is further enhanced with Acetyl Zingerone, a powerful antioxidant that works in synergy with vitamin C to help neutralize free radicals and reinforce skin luminosity. Then, phyto exosomes sourced from green tea leaves are encapsulated carriers that deliver lipids, proteins, and signaling molecules to the skin’s surface. So, this helps support skin barrier resilience and improve overall skin comfort. Last but not least, N-Acetyl Glucosamine, a gentle refining ingredient, contributes to smoother skin texture and helps promote the skin’s own hyaluronic acid production over time. According to brand testing, the formula was shown to brighten the complexion and visibly improve the appearance of wrinkles within 7 days, while causing no barrier disruption. It also demonstrated visible improvements in skin texture and smoothness in the same time frame. All in all, this serum offers a daily boost that leaves the skin looking polished, radiant, and smoother.
