- Background: Photodynamic therapy using topical 5-aminolevulinic acid (ALA) has been successful in treating acne vulgaris, but sun avoidance for at least 48 hours after treatment is necessary due to the risk of post-treatment photosensitivity. Recently, a lower concentration of liposome-encapsulated 5-ALA was introduced to minimize this risk. Objectives: To evaluate the efficacy and safety of liposome-encapsulated 0.5% 5-ALA in the photodynamic therapy of infl ammatory acne and its effects on sebum secretion in Asian skin. Methods: Thirteen Korean subjects with infl ammatory acne were administered 0.5% ALA spray before photoradiation treatment. Photoradiation was performed at 3.5 – 6.0 J/cm 2 three times during each of two visits, performed 2 weeks apart. Improvement of acne was evaluated subjectively and objectively based on the Korean Acne Grading System. Sebum secretion was measured quantitatively at each visit. Results: The mean reduction in acne grade at the end of the treatment was 43.2%. Of the patients, 69.2% reported improvements in subjective skin oiliness, but fewer showed objective reductions in sebum secretion as determined by the Sebumeter ® SM10. No serious adverse events were observed. Conclusion: Photodynamic therapy using liposome-encapsulated 0.5% 5-ALA improved infl ammatory acne with minimal side effects in Asians.
