Description: Formulated with 10% L-ascorbic acid, Serum 10 helps protect against damaging UVA/UVB rays, prevent premature signs of aging and stimulate collagen production. This lightweight, fast-absorbing antioxidant treatment is ideal for sensitive and acneic skin.

This powerful antioxidant reduces the appearance of fine lines and wrinkles, neutralizes free radicals, provides photoprotection and stimulates collagen synthesis.
