Abstract: Base coat as an example of a resin composition for a cosmetic is a resin composition for a cosmetic used in a cosmetic to be adhered to nail as a part of living body. The resin composition for a cosmetic includes a stimulus-responsive material that undergoes a volume change by external stimuli, the external stimuli excluding both an external stimulus due to contact with a solvent and an external stimulus due to contact with a solution, and a solidified matter of the resin composition for a cosmetic has a surface with a water contact angle between 30° and 110° (inclusive). The solidified matter of the resin composition for a cosmetic undergoes the volume change by application of the external stimuli to reduce strength of adhesion to the part of living body.

Abstract: Gel nail device includes: stimulus generator for applying an external stimulus for reducing an adhesion strength between gel nail and nail to at least one of gel nail or nail; sensor for detecting at least one item selected from the group consisting of a position of gel nail, a state of gel nail, a position of nail, and a state of nail; and control circuit for controlling stimulus generator based on a detection result from sensor.
