A cosmetic is characterized by containing a polymer which is produced by polymerizing a fluorine atom-containing monomer represented by formula (I) (wherein R 1 represents a hydrogen atom or a methyl group； R 2 represents a hydrogen atom or a fluorine atom； m is an integer of 0 or 1 to 4； and n is an integer of 1 to 12), (B) a betaine monomer represented by formula (II) (wherein R 3 represents a hydrogen atom or a methyl group； R 4 and R 5 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms； p represents an integer of 1 to 4: and q represents an integer of 1 to 4) and (C) a monomer component containing an alkyl (meth)acrylate represented by formula (III) (wherein R 6 represents a hydrogen atom or a methyl group and R 7 represents an alkyl group having 8 to 22 carbon atoms) with one another.
