Abstract
Background: With the advent of non-ablative devices to treat various aesthetic demands, promising results appeared and are set to become a safe, efficient, and reliable method for scar treatment. In this work, we are going to study the effect of E light (IPL+ RF+ cooling) in treatment of facial scars. Patients and Methods: This study included forty eight patients with persistent post-surgically corrected old and recent facial scars. E light was used, using different filters, according to the skin color. The IPL fluence varied between 38-42 J. RF fluencies varied between 6 and 10 J, and the spot diameter was 8 × 32 mm. Pulse durations of 2-7 ms, and pulse delays of 15–30 ms were used on all patients. Results: Six cases were evaluated as excellent, 34 cases were evaluated as good, and eight cases were evaluated as fair, but all patients stressed that their wounds have been improved. Conclusions: E light induced significant overall clinical improvement in facial scars, particularly in textural smoothing, pliability and scar color. E light was found to give better results when applied early after surgery.
Highlights
Along the human history, facial scars represent a problem, where most of solutions are unsatisfactory
As the pulse durations are usually initiated at the same time, the RF pulse is set at a longer duration versus that of the light energy to preheat the target and so increases RF selectivity [4]
All scars were treated with E light
Summary
Facial scars represent a problem, where most of solutions are unsatisfactory. The synergistic effect of combining radiofrequency (RF) and optical energy allows for lower optical fluencies to be utilized that can be used for a safe treatment of darker skin types [2]. The resultant energy of light creates a preheated area inside the tissue, and directs the RF field into this preheated area versus the surrounding tissue. As the pulse durations are usually initiated at the same time, the RF pulse is set at a longer duration versus that of the light energy to preheat the target and so increases RF selectivity [4]. With the advent of non-ablative devices to treat various aesthetic demands, promising results appeared and are set to become a safe, efficient, and reliable method for scar treatment.
