The antioxidant effects of vitamin C promote the renewal of skin cells while preventing melanin oxidation to gradually lighten discolouration. Phytic acid boosts the effects of vitamin C and exfoliates the skin to return its original brightness. The ROS Modulator system helps repair discolouration and protects against free radicals. HOW TO APPLY Apply a few drops of the serum where needed (face, neck, chest, shoulders, backs of hands) avoiding the area around the eyes for at least 3 months. Over this period, use of very high SPF sun protection and limited exposure to the sun are recommended.
