The beauty secret of celebrity hairstylists, dermatologists and beauty experts. Protect your lashes with this limited-edition contour sleep mask set. Beauty sleep with benefits. The Pure Silk Contour Sleep Mask has been specifically designed with delicate eyelash extensions in mind. The shape of the contour on the inside of the sleep mask has been designed to sit away from your eyelids and allow additional space for your eyelashes to sit while you get your beauty sleep. While Slip has made all efforts to design its contour sleep mask to be suitable for eyelash extensions, Slip acknowledges that not all lashes are the same and the contour sleep mask may not be suitable for all lengths or types of lashes. Slip encourages you to use your own discretion in deciding whether the contour sleep mask is suitable for you. This contour sleep mask is made with slipsilk, the same silk used in the award-winning Slip Pure Silk Pillowcase. Slipsilk has been developed and refined for more than ten years to provide the ultimate combination of shine, thickness, softness and durability. This set is the perfect gift for anyone who values their beauty sleep!
