การศึกษาแบบสุ่มเพื่อเปรียบเทียบประสิทธิภาพของเลเซอร์เออร์เบียมแย้กความยาวคลื่น 2940 นาโนเมตรกับเบนซิลเปอร์ออกไซด์เจลความเข้มข้น 2.5 เปอร์เซนต์ในการรักษาสิวอักเสบ / ณัฐพร โรจน์อารยานนท์ = A randomized controlled trial comparing efficacy of 2940 nanometer Er:YAG laser to 2.5% benzoyl peroxide gel for the treatment of inflammatory acne / Nattaporn rojarayanont
Objectives: To evaluate the effectiveness and safety of Er:YAG laser for the treatment of inflammatory acne in comparison to 2.5% benzoyl peroxide (BP) gel. Methods and materials: Twenty subjects with mild to moderate acne vulgaris were included. One side of the face is randomly selected to treat with 3 laser treatments in 2-weeks interval and the other was treated with 2.5% BP gel. Lesions counts and photo were taken at baseline, week 2, 4, 6 and 10. Three blinded-dermatologists evaluated the photographic clinical changes. Patient satisfaction and adverse events were recorded. Results: At week 2, laser-treated side has statistically difference in inflammatory acne lesion count reduction (16.95%) while BP gel had 2.42% increase (p-value = 0.043). But the difference did not persist after subsequent treatments. Photographic clinical assessment at week 6 showed more improvement of inflammatory acne on laser-treated side comparing to BP gel (p-value = 0.047). Comedone count was not statistically difference between two groups. Patients were more satisfied with result of Er:YAG laser than BP gel for inflammatory acne and acne scars. Adverse events were mild and resolved within 14 days. Conclusions: Er:YAG laser showed immediate result, as effective and safe in treating active inflammatory acne but ineffective for comedonal treatment.
