  • Publication number: 20180015017
    Abstract: The invention relates to the use of glucosylglycerol or glucosylglycerol esters with a view to increasing the expression of cell protective enzymes for the protection and stabilization of human skin and/or mucous membranes. It has been demonstrated that glucosylglycerol plays an effective role in the stimulation and activation of cell protective enzymes such as superoxide dismutase. It is thus possible in this manner to protect human skin cells effectively against damaging external influences.
