A luxurious cleanse! This brush has thousands of soft bristles fine enough to glide through your extensions, reaching the very base of your lash line. The Prolong Lash Cleansing Brush pairs beautifully with the Prolong Lash Cleanser, giving your lashes a deep cleanse while removing natural oils, skin cells, dirt and debris. Perfect for removing eye make, this brush is the best alternative to cotton pads and cotton tips, products which should be kept far away from your eyelash extensions!
