This photodynamic research used chlorophyll photosensitizer and 634nm diode laser to enhance diabetic wound healing rate. 30 male mice (Mus musculus) were divided randomly into six groups, i.e. normal control group, diabetic control group with and without metformin, treatment group with laser beam energy density D1 (1.4 J/cm 2 ), D2 (2.16 J/cm 2 ), and D3 (2.85 J/cm 2 ). An alloxan injection was used to induce diabetic condition (0.13 mg/g mice weight) via intraperitoneal injection. After the topical photosensitizer injection was done, the wounds were exposed with laser beam on the first day the incision wound has been made. Each wound length was measured every day with millimeter ruler. For the wound width, it was measured after Hematoxylin and Eosin staining. The skin tissue was sacrificed on the third day for the histology sample preparation. Laser with energy densities of 1.42 J/cm 2 , 2.16 J/cm 2 , and 2.85 J/cm 2 showed positive results in the wound healing acceleration. The optimum energy density found is 1.42 J/cm 2 . For the next research, it is necessary to find optimum energy density around 1.42 J/cm 2 .
