Design outcomes

Primary

MeasureTime frame
1. Number of hairs in each photo was counted by using magnified screen images from photos taken before treatment and 6 weeks after the end of treatment. Three evaluators independently counted the number of hairs and the mean value was used for the evaluation. To keep the evaluators blind, no information was given about the participants, the axillary side, or the chronology of the photographs. Hair reduction from each axilla, the main outcome measure in this study, was defined as the number of removed hairs divided by the number of initial axillary hairs, and expressed as a percentage. 2. Post-procedural assessment was quantified on a visual analogue scale (VAS) ranging from 0 to 3, 6 weeks after the last session where 0 meant thicker hairs, 1 meant no change observed, 2 meant thinner hairs, and 3 meant the hairs were thinner and weaker.

Secondary

MeasureTime frame
1. Participant's subjective satisfaction scale at 4 weeks after the last treatment, where 1 meant "the treatment did not meet my expectations", 2 meant "lack of satisfaction of the treatment effect", 3 meant "moderate contentment", 4 meant "satisfying effects", and 5 meant "the treatment has met all my expectations". 2. Adverse events were evaluated at each visit by means of physical examination and through the patients' self-report
