The silk material has natural moisturizing properties, making them the perfect material for around your eyes. The tightly-woven fabric keeps moisture close to the skin and stops it from drying out overnight. So, if you spend a whole night sleeping with one on your face, in the morning you should see that the skin around your eyes feels soft and refreshed. If you continue to keep your eyes moisturized during the night, it can help to reduce dark circles and assist in slowing down the ageing process. It is a very easy way to keep your eyes and the surrounding skin looking its best.
