What is the cause of the popping sound that I sometimes hear during treatment?
During thermolysis treatment, high frequency energy is produced at the tip of the probe. When too much energy is delivered, the fluid found in surrounding tissue immediately turns to steam. The rising steam continues to travel upwards, finally being expelled from the follicle with a popping or crackling sound. This sound is characteristic of excessive high frequency treatment and should be considered a warning that permanent skin damage may result.
