Clinical evaluation was performed by a dermatologist. Clinical results were assessed by physical examination, photographic follow-up, and USB microscope (M2, Scalar Corporation, Tokyo, Japan). The results were described as excellent (complete reduction); good (more than 75% reduction), moderate (more than 50% reduction), and poor (less than 50% reduction). VAS: 10 cm visual analog scales. Adverse events reported were slight erythema, scale, and crust.
