The present invention also relates to a process for making up and/or caring for the lips, comprising the application to the lips of a composition according to the invention. Finally, the present invention relates to a device comprising the composition according to the invention.

Provided is a gel polish composition comprising (A) a multifunctional silicone urethane (meth)acrylate oligomer, (B) a reactive monomer, and (C) a photoinitiator. The multifunctional silicone urethane (meth)acrylate oligomer (A) consists of siloxane moieties, urethane moieties, and (meth)acrylate moieties. Also provided is a method of using the gel polish composition.

A photo-curing nail gel composition is provided, including a polyurethane (meth)acrylate resin (resin elongation rate: 200% to 700%), a diluent, a photo initiator, a surface curing accelerating agent and a filler. The diluent includes a monofunctional monomer, a difunctional monomer and a trifunctional monomer. The photo initiator performs the photo-initiation reaction of the composition. The surface curing accelerating agent includes a tertiary amine acrylic resin or a thiol resin. A content of the polyurethane (meth)acrylate resin is 50 wt % to 80 wt %, contents of the monofunctional monomer, the difunctional monomer and the trifunctional monomer are respectively 1 wt % to 30 wt %, a content of the photo initiator is 1 wt % to 10 wt %, a content of the surface curing accelerating agent is 1 wt % to 10 wt % and a content of the filler is 1 wt % to 10 wt %, based on a total weight of the photo-curing nail gel composition.
