A sleep mask made of the highest grade mulberry silk for the ultimate beauty sleep. This luxurious, pure, one-size-fits-all Silk Sleepmask delivers antiaging benefits as it doesn't tug at delicate parts of the face. It's made with the highest quality silk, so it feels extra thick and softer on the eyes. Made using a trade secret production method developed over 10 years, Slip silk provides the ultimate combination of shine, thickness, softness, and durability. This mask is natural, hypoallergenic, dust mite-resistant, and allows skin to breathe unlike synthetic satin (polyester) which sweats, essentially negating the benefits. It does not contain toxic dyes and is recommended by dermatologists, plastic surgeons, hairdressers, and beauty experts. Cotton is very absorbent. It can hold up to 27 times its own weight in water and it draws moisture away from your skin and hair. When you sleep on silk, delicate facial skin is more hydrated in the morning.
