Blissy 100% Mulberry Silk Pillowcase delivers on its promise to give you beautiful hair, glowing skin, and the best night’s sleep. With other pillowcases, natural oils from your hair, skin, and any lotions or serums you put on before bed, are absorbed and build up in your pillowcase. This dries your hair and your skin out and creates a filthy breeding ground for bacteria. Blissy’s silk also reflects infrared heat at the microscopic level keeping you cool while you sleep, and there are no nooks or crannies in the silk where dust mites and other allergens can attach themselves to, making Blissy hypoallergenic.
