The Vitamin C Ultra is a water-based serum that contains a trio of Vitamin C derivatives (Sodium Ascorbyl Phosphate, Magnesium Ascorbyl Phosphate and Ascorbyl Glucoside). Boosted with Vitamin E and Oligopeptide-34 (a brightening/repairing peptide) to provide a combination that packs more of a punch in preventing UV damage than either ingredient can alone. This serum helps battle environmental stressors such as photo-ageing (accelerating ageing from sun exposure) and free radicals that can swindle your skin out of its natural radiance.
