Provided herein are, inter alia, compositions, systems, and methods for preventing or treating acne. Included are compositions, combinations, systems, and methods comprising at least one Propionibacterium acnes bacteriophage, at least one anti-acne compound, and a pharmaceutically acceptable carrier. Also included are compositions, combinations, and systems comprising a Propionibacterium acnes bacteriophage and an enzyme. Methods for preventing or treating acne are also provided.

An object of the present invention is to provide a method of industrially producing a high-purity L-cyclic amino acid more inexpensively and with a high efficiency, from a cyclic amino acid having a double bond at the 1-position. The present invention provides a method in which an L-cyclic amino acid is produced by allowing a cyclic amino acid having a double bond at the 1-position to react with a specific enzyme having a catalytic ability to reduce a cyclic amino acid having a double bond at the 1-position to produce an L-cyclic amino acid.
