Abstract: A cosmetic gel sheet suitable for a cosmetic field or a medical field is provided. The cosmetic gel sheet of the present invention contains carboxy group-containing water-soluble polymer, polyalcohol, and acid as essential constituent components. Carboxy group-containing polysaccharide can be suitably used as the carboxy group-containing water-soluble polymer. Water content in the gel sheet is 30% by weight, but it is more preferable if the water content is 10% by weight or less. In the cosmetic gel sheet of the present invention, the gel sheet can be manufactured by drying an aqueous solution containing carboxy group-containing water-soluble polymer, polyalcohol, and acid as essential components. Wherein, it is desirable that content of the acid in the aqueous solution is adjusted to a value appropriate for setting pH of the aqueous solution to 2.0-4.0.

Abstract: Provided is a new means for administering a valuable substance having a fat dissolving action. A microneedle preparation including at least one of a lipolytic agent, a fat dissolving agent, or a fat metabolism promoting agent, the microneedle preparation being intended for fat reduction and/or partial slenderizing and/or skin tightening, and a microneedle preparation including a microneedle array containing a water-soluble polymer as a base and one or more selected from the group consisting of a lipase, a phosphatidylcholine, and deoxycholic acid.

Abstract: A cosmetic gel sheet suitable for a cosmetic field or a medical field is provided. The cosmetic alcogel sheet of the present invention comprises: a water-soluble nonwoven fabric or a water-soluble film; and an alcogel which is laminated on it and contains carboxy group-containing water-soluble polymer, polyalcohol and acid as essential components, and the sheet is characterized in that the water content of the gel is 30% by mass or less. It is more preferred that the carboxy group-containing water-soluble polymer is carboxy group-containing polysaccharides, and the polyalcohol is glycerin. The cosmetic alcogel sheet of the present invention can be manufactured by: drying an aqueous solution containing carboxy group-containing water-soluble polymer, polyalcohol and acid as essential components on a releasable sheet to manufacture gel, and then laminating the gel on a water-soluble nonwoven fabric or a water-soluble film.
