This vitamin has antioxidant properties (it neutralizes free radicals responsible for the damage and death of skin cells). Royal Balm face serum contains sea buckthorn oil that contains vitamin C at a concentration which is 12 times higher compared to its concentration in orange, as well as pumpkin seed oil which also abounds with this vitamin.
Many women who have a problem with dark spots on the face claim that, for them, the best face serum is the one that consists of 100% vitamin C.
