Abstract: A cosmetic apparatus is disclosed for curing an ultravoilet sensitive coating and bonding material applied to the surface of a person's fingernail optionally including an artificial nail tip attached thereon. The apparatus comprises an enclosure having a front face which defines an opening for the reception therein of the artifical nail tip when applied to the fingernail. A plurality of lamps are disposed within the enclosure for emitting ultraviolet light within the enclosure for curing the ultravoilet sensitive coating and bonding material when the person positions the fingernail and applied nail tip within the enclosure. An electrical timer switch controls the energizing of the plurality of lamps and the time period to which the coating and bonding material within the enclosure is exposed to the ultravoilet light.
