Abstract

The present invention provides a coating formation method with which adhesion between skin and a coating formed by electrostatic spraying is enhanced. The coating formation method of the present invention includes a liquid agent applying step of applying a liquid agent containing one or more selected from water, polyols and oils that are in a liquid form at 20° C., and an electrostatic spraying step of electrostatically spraying a composition directly on skin to form a coating. The liquid agent applying step and the electrostatic spraying step are performed in this order or in a reversed order. The composition includes a component (a) and a component (b) below:
