The present invention provides a method for forming a coating for a cosmetic, with which the adhesion between skin and a coating formed through electrostatic spraying can be increased. The method for forming a coating for a cosmetic of the present invention includes: a cosmetic applying step of applying a cosmetic containing 10 mass % or more of an oil, that is in a solid form at 20° C. onto skin； and an electrostatic spraying step of electrostatically spraying a composition directly onto the skin, thereby forming a coating. The composition contains a component (a) and a component (b) below: (a) one or more volatile substances selected from the group consisting of water, alcohols, and ketones； and (b) a polymer having a coating formation ability.
