Help preserve, stimulate and maximise collagen levels and improve the appearance of lines and wrinkles for younger looking skin with Dr. Brandt Collagen Booster, a concentrated serum infused with key amino acids. Formulated with hydroxyprolisilane CN, a tissue regenerator that stimulates, strengthens and protects collagen and elastin fibres; alistin, which minimises the breakdown of collagen fibres by protecting them from becoming stiff and brittle due to free radicals, sugar, MMPs, and other skin scavengers; isocell map, a stable vitamin C derivative that stimulates collagen synthesis and production; liftessence which improves firmness and decreases surface lines; and an exclusive proprietary custom blend of key amino acids to maximise and strengthen the formation of collagen fibres, Dr. Brandt Collagen Booster noticeably improves the appearance of lines and wrinkles. Directions of use: After cleansing, gently massage on face. Use morning and evening. Follow with your favourite Dr. Brandt moisturiser.
