  • Publication number: 20100263151
    Abstract: A unique device that has two sides, one gauze, one cotton, to allow the cleaning and exfoliating of skin. The device can clean makeup, exfoliate, clean wounds, while changing surfaces, remove makeup around the eyes, face and perform all functions normally serviced by a single sided pad or applicator with a stronger secondary surface that increases the number of uses, and makes the item in issue long lasting for comparable price. The cotton is absorbent, the gauze side strong enough to remove all dirt without deteriorating, and do so faster and more efficiently than cotton alone. It is essentially a potentially two-step device, the delicate side for usage first, followed by the stronger gauze covering as deemed necessary. There is no comparable prior or present art.
