The 0.24 fl.oz brush-applied liquid dries into a thin, waterproof coating that rinses clean with warm water and is designed for daily use after lashes are completely dry. Professional technicians use it in salons and many customers report longer fill intervals when they make the sealant part of their routine.\u003c\/p\u003e\n\n\u003ch3\u003eHow does BL Lashes Black Diamond help my lash fills last longer?\u003c\/h3\u003e\n\u003cp\u003eThe sealant creates a protective barrier around each extension bond, resisting moisture and friction that usually cause early lifting.
