The Bourgeois 3D Faux Mink Eyelashes are a rewareable adhesive eyelash that requires lash glue. Gentle cleansling with Lash Wash or an oil free eyemake remover will extend the life and performance of lashes. No heat or warm water can be applied to the lashes. Allow the lashes to air dry with minimal handling and light brushing. Bourgeois lashes retain their shape once they’re dry.
