Medik8 C-Tetra Advanced 30 ml is a powerful antioxidant serum formulated with a stable, oil-soluble form of Vitamin C (tetrahexyldecyl ascorbate). Designed to help improve skin radiance and clarity, this serum works to brighten dullness, even out tone, and provide daily defense against free-radical damage caused by environmental stress.
The advanced formula penetrates the skin more effectively than basic Vitamin C forms, helping to support collagen health and promote a more luminous complexion. Its lightweight, easy-absorbing texture layers seamlessly under moisturizers and SPF, making it suitable for morning or evening routines.
Ideal for most skin types — including those sensitive to harsher Vitamin C formulations — this serum enhances glow and helps maintain a healthier, brighter-looking complexion with consistent use.
