Protect your lashes and your delicate hair with this limited-edition holiday set. Beauty sleep with benefits. The beauty secret of celebrity hairstylists, dermatologists and beauty experts. Slip Pure Silk products are made using slipsilk, developed and refined for over ten years to provide the ultimate combination of shine, thickness, softness and durability. Slip's 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. Traditional hair ties can tug on delicate hair, which can lead to damage and breakage, but Slip scrunchies are made with slipsilk, the same silk used in the award-winning Slip Pure Silk Pillowcase.
