keraGEN-IV® works synergistically with dietary collagen to boost the body’s ability to produce the right structural proteins to repair wrinkles and strengthen hair follicles and nails. This is achieved by activating skin cells with the right nutritional input to specifically make collagen IV and collagen VII, the binding proteins that join the dermal and epidermal layers essential for smooth, wrinkle free skin as well as anchoring hair follicles into the scalp.
