Abstract: A cosmetic treatment method includes: spraying, toward skin or hair: an atomized medicinal agent in which a medicinal agent containing a predetermined active ingredient is atomized; and fine water that is uncharged and has a particle size of less than or equal to 50 nanometers. Therefore, the sprayed fine water enters the skin or hair to contribute to maintenance of moisturization, and at the same time, forms a route through which the active ingredient permeates, thereby promoting the permeation of the active ingredient; therefore, the permeability of the active ingredient can be more appropriately improved.

Abstract: It is a known fact that when fine water having a particle size of 50 nanometers or less enters the horny layer of the skin, the fine water softens the skin and expands gaps in the horny layer. Therefore, when being used for perfumes or cosmetics, skin external preparations, or the like, lipid membrane vesicles containing the fine water are allowed to easily enter the horny layer.
