The magic ingredient in Immupure's Daily Eye Face Neck Firming Moisturizer - & the whole range - is concentrated Colostrum, the nourishing first milk that a calf gets from its mother. Bioactive Colostrum is naturally rich in immunoglobulines, polypeptides, aminoacids, vitamins & minerals, meaning collagen production is promoted, so fine lines and wrinkles are reduced, skin is tightened & tone improves. New York socialites love this anti-ageing line that really does bring back youthful radiance.
