Medik8 Vitamin C Tetra Serum 30ml

The Medik8 C-Tetra Serum is a vitamin C-based antioxidant treatment designed to protect skin from environmental damage while improving overall tone and texture. It utilises a stable form of vitamin C (ethyl ascorbic acid) that remains effective without causing irritation, making it suitable for daily use. The lightweight, fast-absorbing formula works to combat signs of ageing and sun damage by neutralising free radicals that can accelerate skin ageing. Key features include the combination of vitamin C with vitamin E, which enhances antioxidant protection and provides moisturising benefits. This pairing helps to reduce the appearance of unwanted pigmentation, dark spots, and fine lines by promoting a more even skin tone and plumper-looking skin. The serum is specifically formulated to be gentle enough for sensitive skin types, with clinical studies showing high tolerance rates among participants with sensitivity concerns. This serum is best suited for those looking to address concerns about uneven skin tone, dullness, and early signs of ageing. It fits easily into morning skincare routines, applied after cleansing and before moisturiser and sunscreen. Regular use can help skin appear more radiant and supple, with visible improvements in brightness and smoothness typically noticeable within a week of consistent application. The 30ml bottle provides approximately three months of daily use when applied as directed.
