Special Skin Serum is formulated from what stem cell scientists call a “conditioned medium”. The medium is conditioned by ethically collected human stem cells from placentas and umbilical cords, which release cytokines and other skin regenerating proteins that become available for skin repair.
Blue Horizon invented a proprietary process that stabilizes the liberated cytokines, rendering them safe and accessible for aesthetic skin improvement. An independent skin test on twenty individuals aged 46 to 81 found a 23% reduction in skin roughness, including a decrease in the appearance of fine lines, wrinkles and scars.
