Dear editor
We are very happy to have the opportunity to discuss our research, and thanks much to the authors for some suggestions. We will improve the future research according to the suggestions. Here, we respond to the questions raised by the authors.
First, as for the single application of RF or IPL in acne treatment, we have conducted clinical application before, and the therapeutic effect is limited. However, because it is not within the statistical scope of this experiment, the data are not shown. In addition, due to the cost of testing during combination therapy, patients are unable to undergo more objective instrument testing, so no complete data of objective indicators have been collected. And, patients personally agreed with the treatment plan and treatment effect, so only subjective reports were used in this study. However, based on a large number of samples, we can preliminarily draw relevant data and conclusions. We will do a more thorough analysis in the future.
Second, we conducted a patient satisfaction survey, but it is not shown in the article. After the last treatment, patients made self-evaluation of the efficacy, which was divided into four grades: very satisfied, satisfied, general and dissatisfied. Satisfaction rate = (very satisfied + satisfied)/total number of cases. The results showed that after the treatment, among the 500 patients, 348 (69.6%) were very satisfied, 152 (30.4%) were satisfied, and the satisfaction rate was 100%.
Third, thanks for your suggestions. Although the photo angles and ambient light have been changed, it is intended to show the scene of the patient’s severely affected area as fully as possible. In addition, the data was obtained, which based on the statistical analysis of a large number of samples.
During the treatment, the patients did not receive other skin treatments.
Finally, due to the local medical environment, we have not been able to conduct clinical research with other medical institutions. This is what we will strive for in the future.
