Abstract: A method for producing a coating film on skin, including applying a composition (B) onto the skin and applying a coating film including a deposit containing a fiber to the skin. The composition (B) includes carbon dioxide gas. A kit for forming a coating film, including a composition (B) including carbon dioxide gas and a coating film including a deposit containing a fiber or a composition for forming a coating film.

Abstract: The present invention relates to a method for treating skin, comprising the following step A) and then step B): A) physically or chemically treating an epidermis of the skin; and B) forming a film containing a fiber deposit on the skin which has been subjected to the step A). When the above step B) is applied to the skin after the conventional step A), skin conditions such as inflammation, redness, and swelling caused by the step A) are alleviated, these conditions disappear more quickly, and the quality of life (QOL) of persons who have undergone the cosmetic or dermatological treatment is significantly improved.

Abstract: A low pH skin-treatment composition employs cationic surfactants generally known to be skin irritants and a fatty acid, together with a hydrocarbon component in an oil-in-water emulsion. The addition of fatty acid to the cationic surfactant appears to form a complex which prevents the cationic surfactant from irritating the skin and at the same time substantially reduces pH of the composition. The resulting composition is not skin irritating, and reflects a pH of about 2-4. The composition may be used to restore pH of skin after exposure to alkaline compositions, and as a vehicle for the administration of active agents having an acidic pH.
