A nail tip curing composition includes an Extend Gel, an edge-off flat brush, a nail filing device, a plurality of GEL-X tips, a pH Bonder, and a Non-Acidic Gel Primer. The pH Bonder forms a pH Bonder layer on a surface of a fingernail. The Non-Acidic Gel Primer forms a Non-Acidic Gel Prime layer overlapped on the pH Bonder layer. The Extend Gel forms an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer. The GEL-X tip is filed by the nail filing device and the Extend Gel is applied on an underside contact surface of the Gel-X tip by the edge-off flat brush. The underside contact surface of the Gel-X tip is contacted with the Extend Gel layer on the fingernail in such a manner that the Gel-X tip is firmly affixed on the fingernail.

A nail enhancement includes a conductive substrate configured for placement proximal to a nail of a wearer and a color-changing layer comprising a chromic material that is integrated with the conductive substrate. A power source is in direct or indirect physical contact with the color-changing layer. The color-changing layer is activated to change appearance by the power source.

A nail enhancement includes a conductive substrate configured for placement proximal to a nail of a wearer and a color-changing layer comprising a chromic material that is integrated with the conductive substrate. The color-changing layer changes appearance when activated. The chromic material may be an electrochromic material, and the color-changing layer may change appearance when activated by a change in electrical current. The chromic material may be a thermochromic material, and the color-changing layer may change appearance when activated by a change in temperature.

A nail enhancement includes a conductive substrate configured for placement proximal to a nail of a wearer and a color-changing layer comprising a chromic material that is integrated with the conductive substrate. A method of customizing the appearance of a fingernail or toenail includes providing the nail enhancement, adhering the conductive substrate to the fingernail or the toenail, and activating the color-changing layer by providing electrical current or heat to the color-changing layer. The nail enhancement may also be used in methods of exchanging information, including methods of making payments using the nail enhancement.

An artificial nail includes an artificial nail body which is convex upwardly. The artificial nail body has an upper surface and a lower surface opposite to the upper surface. The artificial nail body further comprises a blocking surface which extends downwardly from a rear edge of the lower surface and is located between the lower surface and the upper surface. During the adhesive application and pressing process, any adhesive that tends to overflow outward is initially blocked by the blocking surface. For the adhesive to leak, it must overcome the barrier of the blocking surface. Thus, the adhesive is unlikely to overflow from the lower surface, thus preventing any impact on the nail's aesthetic appearance.

A light-curable artificial nail includes an adhesive section having a light-curable composition in a semi-cured state. The light-curable composition is configured to transition from the semi-cured state to a cured state based on exposure to at least one wavelength of electromagnetic radiation.
