Provided is an eyelash extension adhesive comprising the following components (a) and (b): (a) a monofunctional monomer of formula (I) wherein R.sup.1 represents a hydrogen atom or a methyl group, and R.sup.2 to R.sup.6 each independently represent a hydrogen atom or a C1 to C6 alkyl group, and (b) a photopolymerization initiator. The eyelash extension adhesive is excellent in durability and water resistance, can adhere easily to eyelashes even in a wet state, and is very useful as a photopolymerizable adhesive for eyelash extension attachment not including a cyanoacrylate compound.

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.
