Our face masks are designed with comfort, reusability and function in mind. Two layers of soft silk to protect you that are kind and gentle on your skin, and keep you looking cute while you’re out and about. Intricately made with covered scrunchie ear loops, making them super comfy to wear for long periods while soft silk is delicate on your skin.   

Info: Made in Los Angeles from two layers of 100% silk charmeuse. Luxurious treat for your skin. Silk is delicate on skin and can help to avoid irritation and “maskne”.

From the maker: For washing I recommend hand washing and line dry, however I do machine wash mine on cold and line dry; I just always use extra caution but mine are totally fine being tossed in machine.
