A system and method for manufacturing custom fit artificial nails includes a 3D surface scanning module and a 3D printing module and use thereof. A central processing module is connected to the 3D surface scanning module and the 3D printing module and performs: operating the 3D surface scanning module to obtain an image of a user's hands/feet; processing the image to create an input 3D model of nails of the user; generating an output 3D model corresponding to artificial nails matching dimensions of the user's nails according to the 3D input model; operating the 3D printing module to manufacture artificial nails according to the output 3D model; and generating medical data by correlating the identified features of the user's nails with known medical conditions, in order to diagnose a medical condition of the user which is known to exhibit the identified features as a symptom. Alternatively, or additionally, medicinal ingredient may be included in the artificial nail to treat the medical condition of the user. Embedded devices, sensors or an RFID chip may be integrated into the artificial nail.

The illuminated press on nail is a press on nail. The press on nail is a cosmetic structure that is worn by a client on a location selected from the group consisting of a finger nail and a toe nail. The illuminated press on nail comprises a press on nail, a control circuit, and a personal data device. The control circuit mounts is an illumination circuit that mounts in the press on nail. The personal data device forms a wireless communication link with the control circuit. The personal data device controls the operation of the control circuit. By controlling the operation is meant the personal data device controls the color of the illumination generated by the control circuit.
