A method and a hand-held device for dermaplaning is disclosed that includes a blade assembly which includes a blade, a blade holder and a safety cage. In accordance with an important aspect of the invention, the safety cage limits the amount of penetration of the blade into the facial skin to enable the device to be safely used by non-professionals. The dermaplaning device includes a vibration generator that causes the blade to vibrate at a predetermined frequency. Various embodiments of the hand-held dermaplaning device are disclosed for vibrating the blade.
