The Erasee gently and easily helps to remove unwanted hair. And now you can buff your hair away from even the most sensitive areas with the Precision Buffer! When rubbed gently on the skin it allows hairs to clump and break from the surface. Using nano-crystal technology, it helps to exfoliate skin, reduce ingrown hairs, and improve elasticity and firmness! WOW Erasee is designed to slow hair regrowth within a few uses. It's highly environmentally friendly, in that it's reusable and doesn't require any kind of refill or charging. With recommended use, the Erasee will last up to 3 years, saving you money on more expensive hair removal options! Please Note: If you have sensitive skin, test on your arms or legs first before using on other delicate parts. Please use the precision buffer rather than the body buffer on small or sensitive areas such as the upper lip, bikini line, underarms, etc.
