Key Points

This research aims to evaluate the effects of facial endolaser treatment on skin laxity.
Eight patients treated with 1444nm Nd:YAG laser using a naked optical fiber.
Patients assessed with Digital photographs and Scientific Assessment Scale of Skin Quality at 6-month follow-up.
Pain levels recorded on a 5-point scale during treatment.
Pain reported ranged from moderate (2) to severe (3) on a 5-point scale.
Significant improvements noted in most parameters of skin quality (P < 0.05).
Qualitative photographic analysis confirmed noticeable skin improvement in most patients.

Abstract

Background and Objectives: Facial skin ptosis is a very common condition that affects people of both sexes and across a wide age range.This study reports some clinical cases involving the treatment of facial skin laxity using a naked optical fiber connected to a laser with a pulsed emission at 1444nm, normally used to act on adipocytes thanks to its laser lipolysis action.Materials and Methods: A total of 8 patients with facial contour loss, subcutaneous fat deposits, facial flaccidity and wrinkles underwent a single session of endolaser treatment performed using a 600-m-diameter optical fiber connected to an 1444 nm Nd:YAG laser.Digital photographs of each patient's face were taken before treatment and at a 6-month follow-up.All patients were evaluated with monthly follow-up visits for one year in order to monitor the possible adverse effects.Clinical effects of the treatment were evaluated with real time assessment using the Scientific Assessment Scale of Skin Quality (SASSQ).The patient's perception of pain during treatment was assessed using a 5-point scale.Results: The intensity of pain experienced during treatment was reported to be moderate to severe, as indicated by a 5-point pain scale value of 2 and 3, respectively.The results of the SASSQ questionnaire revealed significant variations (P < 0.05) for most of the parameters considered.The photographic analysis confirmed improvement in most cases, as assessed qualitatively by the two treating physicians.Conclusions: Facial laser treatment for endolifting offers a great opportunity to improve skin laxity in facial areas affected by skin ptosis.It is a minimally invasive, effective and safe procedure, with minimal recovery time and appreciated by patients.
