A nail treatment method includes: a base step of forming a base layer (40) on a nail plate (3); a coloring step of forming a color layer (50) on the base layer (40); and a top step of forming a top coat layer (60) on the color layer (50). In the base step, the base layer (40) is formed so as to be spaced apart from the base of the nail plate (3), and furthermore is formed in a shape including a raised part that has a highest portion at a position that is closer to the base of the nail plate than a position one-half of the length of the nail plate (3) is.

The present invention relates to energy-releasable beauty care products. The products are capable of absorbing energy, for example, from an electrical, magnetic, electromagnetic, light, or heat source, which alters the physicochemical state of the beauty care product such that it is easily removable through the utilization of the energy source.

A light source and a power source are held between upper and lower shells of a fake nail tip. The fake nail tip is provided with its shells hinged open and the light source unactivated. As the shells are brought together, an electrical contact is made between the power source and the light source, which causes the light source to illuminate the fake nail tip. The shells are then fastened together to maintain the light source illuminated.
