The present invention relates to complex particles using methylene blue for treating a skin disease caused byorand a composition for treatment including the complex particles. The complex particles in the present invention can be used as a photosensitizer for a photodynamic therapy and complex particles having a micelle form in which hydrophilic methylene blue and two hydrophobic organic acids are combined, and as a result, pore penetration is easy and an occlusion time can be significantly reduced to 30 minutes as compared with conventional phototherapy requiring an occlusion time of 1 hour to 3 hours. Further, in order to reduce side effects of a residual photosensitizer in phototherapy using an existing photosensitizer due to photoreaction and photobleaching of the methylene blue-organic acid complex, a light protection (light blocking or light shielding) time when contact of light needs to be avoided for 24 hours or more after treatment can be significantly reduced to 3 hours, and target treatment for, or the like which is a cause of acne is possible.
