A method for producing a wearable coating having a solid material fixed on skin, the method comprising: A) a step of placing one or more solid materials selected from the group consisting of a powder, a granule, a film, a fiber, a flat material, and a cubic material other than these, on a skin surface; B) a step of, after the step A), electrostatically spraying a composition X comprising the following component (a) and the following component (b) directly on the skin to thereby form a coating on the skin surface: (a) one or more volatile substances selected from the group consisting of water, an alcohol, and a ketone, and (b) a polymer having a coating forming ability; and after the step B) or before the step A), C) a step of applying a composition Y, other than the composition X, comprising one or more components selected from the group consisting of the following component (c) and the following component (d) to the skin: (c) an adhesive polymer, and (d) an oil.

Method for producing wearable coating

A method for producing a coating on skin, the method comprising: A) a step of electrostatically spraying a composition X comprising the following component (a) and the following component (b) directly on the skin to thereby form a coating on a skin surface: (a) one or more volatile substances selected from the group consisting of water, an alcohol, and a ketone, and (b) a polymer having a coating forming ability; and B) a step of applying a composition Y, other than the composition X, containing the following component (c) and the following component (d) to the skin: (c) 5% by mass or more and 20% by mass or less of an adhesive polymer, and (d) 1% by mass or more and 40% by mass or less of a polyol, in this order or in reverse order.

Method for producing coating

Methods involving: A) placing one or more solid materials on a skin surface; after step A), B) electrostatically spraying a composition X comprising (a) one or more volatile substances selected from water, an alcohol, and a ketone and (b) a polymer having a coating forming ability directly on the skin to thereby form a coating on the skin surface; and after step B) or before step A), C) applying a composition Y, other than the composition X, comprising one or more components selected from the group consisting of (c) an adhesive polymer and (d) an oil component (d) to the skin, are useful for producing a wearable coating having a solid material fixed on skin.

Methods for producing a cosmetic coating on a skin surface, by: (A) electrostatically spraying a composition comprising component (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, and component (b) a polymer having a film-forming ability directly onto the skin to form a coating on the skin surface; and (B) subsequently applying a powder-containing cosmetic on the formed coating, afford cosmetic coatings which can be removed without using a cleansing agent.
