Natural Home Luxe Mulberry Silk Pillowcases uses 100% premium mulberry silk made from the highest quality long-strand silk spun to the highest silk density of 25 momme. The density means our mulberry silk pillowcases are tightly woven to produce a luxuriously smooth and natural sheen making the silk breathable and ultra soft. The natural sheen and tightly woven fibres help regulate a natural, comfortable, calming temperature for the perfect night’s sleep. Silk naturally contains protein and 18 essential amino acids known to protect the skin from free-radicals and reducing the signs of aging. Natural fibres keep your skin moisturised and hydrated throughout the night by providing moisture balance to the skin and reducing sensitive skin conditions such as dermatitis. Your hair will also benefit from the natural fibres. Wake to have your hair moisturised, soft, tangle-free and shiny. Silk is the most hypoallergenic fibre. Dust mites, mould, fungus allergies or asthmatics will notice the sleep difference with our silk pillowcases.
