Injectable Polyethylene Glycol Gel as Dermal Filler: 01 Year Clinical and Ultrasound Follow-Up

Abstract

Facial alterations that occur with aging are result of combined effects of soft tissue atrophy with loss of facial volume, gravitational factor and decrease of elastic tissue. In order to minimize these alterations, minimally invasive procedures such as cutaneous filling have been gaining space in clinical practice. In 2008, Scientech CorporationItalia introduced hydrogel of polyethylene glycol (PEG) REMAKE ® as cutaneous filler. This prospective study was developed to prove the effectiveness, safety and durability over the 12 months after the application of PEG hydrogel, commercialized under the name of REMAKE ® . 40 female volunteers were included, between 30 and 60 years, with signs of malar region volume loss between 2 and 3 (Raspaldo's classification) and Nasogenian furrow accentuation, with score between 2 and 3 (Day and collaborators' classification). No patient had carried out procedures of temporary filling for 1 year or permanent filling at any time. Objective parameters always show the scale of the improvement and an evaluation was selected through ultrasound exams and surface scan for evaluation of size and depth of wrinkles improvement. Evaluations by the US were carried out for 30, 120 and 360 days of product use, in a pilot group of 18 patients randomly selected to measure the product in the application plan and numerically assess alterations of volume (absorption/migration). Its durability of up to 01 year after application is proved when no significant reduction.
