     In this embodiment, the contactable photocosmetic device  22  in the phototherapy system shown in  FIG. 18  is composed of only the optical fiber layer  221 , the second optical fiber filaments  2211  composed of side light-emitting optical fiber are interweaved in the optical fiber layer  221 . As shown in  FIG. 21  showing a schematic structural diagram of the side light-emitting optical fiber, the side light-emitting optical fiber is interwoven in the optical fiber layer. The side light-emitting optical fiber is made of transparent plastic, and the curved optical fiber emits light from the side thereof, thereby achieving uniform light emission of the optical fiber layer  221  in the phototherapy system.  FIG. 18  is a schematic diagram of the actual application when the contactable photocosmetic device  22  in the phototherapy system of the present application is only an optical fiber layer, and the contactable photocosmetic device  22  is a contactable facial mask.
