Topical antiperspirant applied as an astringent prior to applying latex, gelatin, Bald Caps, silicone appliances or make up. Inhibits perspiration with repeated use. Not a barrier or sealer but an active antiperspirant. Used by Presidents and performers worldwide. Trusted by professionals for decades. Don't be fooled by imitations and impostors that don't work because they are made for street wear and contain materials like aloe, waxes plasticizers or oils. These ingredients will inhibit adhesion and keep your make up from lasting throughout the performance. Trust the product MADE for performers.
