Soy-derived lipid molecules demonstrate strong biomimetic and soothing properties. Soybean oil forms a protective film on the skin. Soya is also an excellent source of proteins. Zelens uses soya since it moisturises skin, helps prevent water loss and strengthens the natural barrier function. Isoflavones from soya stimulate production of collagen and elastin while proteins extracted from soybeans increase energy production and help preserve cellular longevity. Soy proteins also nourish eyelashes and improve their tensile strength and texture.
