Let's get down to the nitty gritty. Cleansing your fresh lash extensions is KEY to having the best retention... having the proper tools helps, too. Meet the Aura Lash Cleansing Brush. Made with the finest, synthetic fiber white bristles... not too firm but not too flimsy. It will get down and not-so-dirty (see what I did there!) with your lashes. Gently works to wipe away impurities including dirt, oil + makeup that tend to chill on your lash line for the cleanest + happiest lashes.
