Abstract

Objectives

This study aims to evaluate the safety of the radiofrequency device and its efficacy in various treatment and refrigeration modes.

Methods

Four 4-week Bama miniature pigs were used in this study, and four repeated treatment sites were selected on the pig's abdomen, each site consisting of 6 different treatment and cooling modes, with radiofrequency device (YouMagic; WE Medical Technology Co., Ltd.) administered every 3–5 s for a total of five treatments. The handheld infrared thermometer (HIKMICRO; Hangzhou Hikmicro Sensing Technology Co., Ltd.) was used to monitor the surface temperature of skin. Twenty minutes after the completion of treatment, a biopsy of the treatment and control area was performed on the pigs using a 4-mm biopsy punch. One-month after the treatment, samples were obtained using surgical scalpels. After that we used proper staining to estimate the therapeutic efficacy. At last, SPSS and Image J were used to proceed to the next step of analysis.

Results

During the therapy, no side effects were observed apart from mild transient erythema caused by the heating of skin temperature, staining of biopsy samples taken 20 min after treatment showed no serious damage of dermis. After 1 month of treatment, it can increase collagen I and elastin production. In addition, increases in energy setting at a standard pass number also increased the expression of collagen I. Meanwhile, we also found an increase in the thickness of the dermal layer among all treatment groups.

Conclusions

The new monopolar radiofrequency instrument possesses excellent therapeutic safety. After 1 month of treatment, it can increase collagen I and elastin production in 2-month-old Bama miniature pigs.
