A nail production system according to an embodiment of the disclosure includes a first correction section and a first conversion section. The first correction section corrects shape data of an existing nail tip or an existing nail sticker on the basis of measurement data of a nail, to thereby generate shape data of an original nail tip or an original nail sticker. The first conversion section converts the shape data of the original nail tip or the original nail sticker that is generated by the first correction section into print data.

Photopolymerizable compositions for forming a cosmetic nail coating or artificial nail and methods of using such compositions. The compositions include (a) at least one rheology modifier; (b) from about 15 wt % to about 80 wt % of one or more (meth)acrylate oligomers; (c) from about 5 wt % to about 60 wt % of one or more (meth)acrylate monomers; and (d) one or more photoinitiators; wherein the at least one rheology modifier is selected in an amount such that the viscosity of the composition is greater than 400,000 centipoise (cps) at 25 C. The compositions may be a liquid or a gel capable of forming an artificial nail or cosmetic nail coating in one application and without being mixed with any additional components.

A method for removing an artificial fingernail from an underlying natural fingernail to which it is attached by an adhesive has the steps of: (a) soaking the fingertips in warm, soapy water; (b) providing a prying tool comprising a thin, smooth sheet of semi-rigid material; (c) inserting the prying tool between the artificial and the underlying natural fingernails; (d) lifting the artificial fingernail away from the underlying natural fingernail; and (e) manually removing the artificial fingernail from the fingertip.

The invention provides a nail foil adornment method and apparatus which cosmetically strengthens, fills, protects and repairs imperfections on natural or artificial nail plates. The adornment apparatus is comprised of two non-thermal flexible adhesives, color or pattern polyester Mylar foil film, opaque polyester Mylar film and clear nail polish. The method is comprised of brushed on transfer adhesive to the bare nail plate which dries clear, level and tacky (sticky). The color or pattern polyester Mylar foil film is digitally pressure transferred onto the nail plates dry tacky (sticky) surface. The used clear film carrier is discarded. The second flexible adhesive is applied to the foiled nail. The adhesive dries clear, tacky (sticky). The opaque polyester Mylar film is digitally transferred onto the nail plate creating a protection layer. The film carrier is discarded. The foiled nail is sealed with clear nail polish to extend wear.

The present invention relates to a process for manufacturing a false nail, comprising the following steps: a) producing by additive manufacture, from 3D digital data originating from the acquisition of a relief, especially that of the finger intended to receive the false nail, a mold using a first material, b) depositing onto the mold a layer formed from at least one adhesive composition, c) depositing onto the mold at least one layer of a coating of a second material, different from the first, so as to form the false nail.

The invention relates to a device for hardening nail varnish by ultraviolet radiation. The device comprises: a bearing surface (26) intended to support the hands or the feet of the user, radiation sources (38) able to emit a radiation to harden nail varnish in the form of a light beam to illuminate the nails of the user. The beams define on the bearing surface (26) at least six illuminated portions (42) separated from each other by a non-illuminated portion, with the number of illuminated portions (42) being less than nine.
