The present invention is a water-in-oil emulsion having a high content of water and relatively high amounts of skin-moisturizing agents and a cosmetic or dermatological stick including the water-in-oil emulsion. The present invention also includes methods of moisturizing the skin using the water-in-oil emulsion. The water-in-oil emulsion is solid at room temperature and comprises a fatty phase with at least one oil component and at least one wax component, an aqueous phase with a skin-moisturizing agent in addition to water, a water-in-oil emulsifier having the general structure A-B-A&prime, where A&prime and A&prime represent the same or different hydrophobic inorganic groups and B is a hydrophilic group.
