  • Patent number: 11116842
    Abstract: The present invention relates to complex particles using methylene blue for treating a skin disease caused by Propionibacterium acnes or Staphylococcus aureus and 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.
