Abstract: The present invention relates to a complex particle, prepared by using methylene blue, for treating skin disease caused by Propionibacterium acnes or Staphylococcus aureus and a treatment composition comprising the same complex particle. The complex particle is used as a photosensitizer to be use for photodynamic therapy and is formed as a micelle type by complexing methylene blue, as a hydrophilic group, and two types of organic acid as hydrophobic groups. The complex particle penetrates skin pores in an easy manner and thus can significantly reduce the waiting time compared to conventional photodynamic treatment which requires 1-3 hours of waiting time. In addition, the complex particle can significantly reduce light protection (light blocking or light shielding) time during which a user had to avoid contact with light during 24 hours or longer after treatment to minimize the side effects of any remaining photosensitizer in a light treatment using a conventional photosensitizer to three hours or shorter due to photoreaction and photo-bleaching effects of the methylene blue-organic acid complex.
