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.

Generally, devices and methods for accelerating/decelerating a skin are disclosed. The method may include applying an applicator to a selected location on the skin, and periodically and mechanically moving/displacing the skin by the applicator according to a specified acceleration/deceleration pattern and at specified acceleration/deceleration values

A noninvasive method for tightening loose neck skin embodying a non-expensive, indiscrete external tensioning device is provided. The tensioning device is adapted to physically tension and tighten the loose neck skin. The tensioning device may be an elongated thin sheath defining a first surface and an opposing second surface. The first surface provides an adhesive portion that may be adhered to the back of a user's neck is such a manner so as to pull their frontal neck skin upward and backward for effectuating a noninvasive facelift thereof. Embedded between the first and second surfaces may be an integrated memory wire adaptable to move to a pinched condition providing additional tension force between the opposing ends of the tensioning device, and in turn to the neck skin.

The present invention relates to a method of preparing a dry hydrogel sheet including the steps of: preparing a cellulose ether dispersion solution; transferring the dispersion solution to a coater while maintaining the temperature of the dispersion solution in the range of a gelation temperature of the dispersion solution to a boiling point of a dispersion medium; applying the dispersion solution transferred to the coater as a sheet; preparing a hydrogel sheet by cooling the applied dispersion solution to induce gelation; and drying the hydrogel sheet. Since the dry hydrogel sheet prepared by the method has a low moisture content, it is possible to ensure the stability of active ingredients, quantify functional components to be applied to the dry hydrogel sheet, and ensure the uniformity of the surface appearance and thickness of the dry hydrogel sheet, which results in the improvement of the quality of a final product.
