Abstract: The present invention relates to an enzyme for producing hydroxy derivatives of polyunsaturated fatty acids, a method for producing hydroxy derivatives of polyunsaturated fatty acids using the same, and an SPMs complex composition containing the hydroxy derivatives of polyunsaturated fatty acids. The enzyme may produce hydroxy derivatives of polyunsaturated fatty acids in a single reaction, and thus may be very usefully used for in vitro production. In addition, the SPMs complex composition containing the hydroxy derivatives of polyunsaturated fatty acids promotes collagen production, inhibits the production of NO and expression of TNF-? and IL-6, increases the expression of filaggrin and loricrin, and thus may be usefully used for preventing or alleviating skin aging or wrinkles, strengthening skin barrier, or preventing, alleviating or treating skin diseases comprising atopic dermatitis.
