Prevent the development of fine lines, dark spots and slackness with Tri Vita C30 serum from Dermaceutic. This innovative formula is one of the most powerful available and contains a combination of three different forms of Vitamin C (15% L-Ascorbic Acid, 14.5% Ascorbyl Silanol and 0.5% Ascrobyl Ester) that promise to reach several layers of the skin, providing longer lasting protection and rejuvenation than ever before. Added Ferulic Acid and Vitamin E provide enhanced antioxidant benefits to counteract oxidative stress while encouraging collagen production within the lower layers. Over time, skin becomes smoother, firmer, brighter and noticeably more radiant.
