Key ingredients include Ultra-Pure Medical Grade Lanolin (Medilan®) which is an extraordinary natural emollient that is able to imitate many of the functions of human skin lipids. Medilan® is nearly twice as effective as the physiological lipids in human skin. It has been shown to maintain skin hydration for up to 2 days after application. Medilan® has also been shown to increase the rate of epidermal healing by 35% due to its ability to create a moist wound-healing environment. Studies have shown no allergic or irritant skin reactions, even in severely compromised skin.
