【Task】 An object of the present invention is to provide a skin external preparation having coenzyme Q10 coexisting with a biological component-like polymer and having excellent skin retention of coenzyme Q10. [Solution] By containing the biocomponent-like polymer having a partial structure represented by the general formula (II) and coenzyme Q10, the skin retention of coenzyme Q10 was improved. [Chemical 2] Formula (II) (Wherein, R 1 represents an alkyl group having 1 to 4 carbon atoms, R 2 is - (OC 2 H 4) -R 3 or an amino acid residue .R 3 represents a phosphorylcholine group, or a sugar residue.) |
