| アブストラクト | BACKGROUND: Acne vulgaris poses a significant dermatological challenge, necessitating alternative treatments due to limitations and side effects associated with current therapies. This pilot clinical trial investigated the feasibility and efficacy of precision cryotherapy for acne vulgaris. METHODS: A total of 20 volunteers underwent targeted precision cryotherapy using a carbon dioxide-based device. Treatment outcomes were assessed using various parameters, including Investigator Global Assessment (IGA) score, acne lesion count, erythema index (EI), global evaluation score, and participant satisfaction. Safety monitoring included adverse event reporting and physical examination. RESULTS: Precision cryotherapy demonstrated a significant reduction (90.25%) in the acne lesion count by week 4, with clinical improvement indicated by IGA score reduction (p < 0.001). The EI showed notable improvements at weeks 1, 2, and 4. The global evaluation score demonstrated a 75%-100% clinical improvement at Visit 4. Participants reported high satisfaction (6.75 +/- 0.79) with the procedure. No adverse event or discomfort was reported. CONCLUSION: Precision cryotherapy effectively improved acne lesions, which was safe and satisfactory for participants. These findings suggest its potential as an alternative therapeutic modality, especially for populations with limited treatment options. Further research is needed to validate the results and explore underlying mechanisms. |
