Abstract
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.

A method for producing a coating on skin, comprising:
- A) a step of electrostatically spraying a composition X comprising the following components (a) and (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 formability;
- and
- B) a step of applying a composition Y, other than the composition X, comprising the following components (c) and (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.
A composition Y for being applied to skin,
- wherein the composition Y is a composition used for producing a coating on skin by applying the composition to the skin by using a device other than an electrostatic spray device, before or after a coating is formed on a skin surface by electrostatically spraying a composition directly on the skin, and comprises the following component (c) and the following component (d):
- (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.
A method for applying a composition Y to skin,
- the method being a method used for producing a coating on the skin by applying the composition Y to the skin by using a unit other than electrostatic spraying, before or after a coating is formed on a skin surface by electrostatically spraying a composition directly on the skin, wherein the composition Y comprises the following components (c) and (d):
- (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.
