Lash & Brow Oil -- 1 oz This is fast drying oil designed to help you achieve fine lines. For brows and lashes DO NOT mix with the paint as it will eventually start drying out your pile of paint. Mix your paint with Mix & Paint Oil and use Lash and Brow Oil to wet your brush. Exception -- When painting eyes, you can mix your paint with Lash & Brow Oil and paint successive layers by allowing each layer to dry first before applying the next.
