Clinical trial of pin-point photodynamic therapy using an optic fiber for the improvement of enlarged facial pores: A case study

Abstract

Background: There are few publications on the treatment options for facial pore size reduction. A focused therapy is needed. Objective: To evaluate the efficacy of selective photodynamic therapy (PDT) using an optic fiber for the size reduction of large facial pores. Methods: A series of five patients (skin phototypes IV–V) with large facial pores received two successive weekly treatments with an 810-nm diode laser using a fine optic fiber after indocyanine green (ICG) was applied selectively to enlarged pores. Patients were evaluated using digital photography at each treatment session, and at 3 months post-operation. Clinical assessment scores were determined at each treatment session and follow-up visit. Patient satisfaction surveys were obtained at the end of the study. Results: All five participants who completed the 3-month follow-up gave a subjective assessment of reduction of facial pore size. Modest to excellent improvement was achieved. Conclusion: This study demonstrates that treatment with pin-point PDT using an optic fiber is a well-tolerated and effective regimen for the reduction of facial pore size.
