SkinCeuticals' Serum 10 is a powerful yet easily tolerated antioxidant that helps to protect and perfect delicate, problematic skins. Formulated with 10% L-Ascorbic Acid (Vitamin C) and 0.2% Ferulic Acid, this serum reverses and prevents free radical damage and photo-ageing while actively stimulating collagen production to plump fine lines and wrinkles at the surface. Once applied, it stays on the skin all day and remains efficient for up to 72 hours, making it a great partner to any sunscreen.

Suitable for normal, sensitive, and problematic skin types, apply a few drops to cleansed skin every morning for best results.
