Novel method for facial rejuvenation using Er:YAG laser equipped with a spatially modulated ablation module: An open prospective uncontrolled cohort study

Abstract

Facial aging is a complex biological process that affects the skin and superficial musculoaponeurotic system (SMAS). A new technology (RecoSMA) for skin rejuvenation based on acoustic-interference method using Er:YAG laser (2936 nm) equipped with a special module SMA that targets both the dermis and SMAS was evaluated in an open-label prospective cohort study of 100 female patients treated for facial rejuvenation. Measure of clinical improvement included investigator-rated clinical photography using the Modified Fitzpatrick Wrinkle Scale, and ultrasound measurements in the dermis a week, 30 days and six months post treatment. All patients completed the study and no complications were noted. Improvements in skin tone and texture were noted in all participants and significant decrease in wrinkle depth was demonstrated at the six-month follow-up that was confirmed by ultrasound skin measurements. Data presented herein confirm the safety and efficacy of RecoSMA treatment for facial rejuvenation.

Treatment of psoriatic skin lesions with a new Er:Yag laser technology: A case series study

“…It is performed using an Er: YAG laser (2,940 nm) and a special treatment head SMA. In essence this method takes advantage of the radiation of an erbium laser with a wavelength of 2,940 nm, which is well absorbed by water and is space modulated in such a way that an energy flux is applied to the treated surface with an ordered alternation between the maxima and minima the density of the energy (Alcolea et al, 2017;Hersant, SidAhmed-Mezi, Chossat, & Meningaud, 2017;Trelles & Khomchenko, 2019;Trelles, Khomchenko, Alcolea, & Martinez-Carpio, 2016;Volkova, Glazkova, Khomchenko, & Sadick, 2017;Volkova, Valamina, Shvidun, Rebrieva, & Sadick, 2019). The energy emitted in pulses, when interacting with the tissue modulates spatially which means that the energy affects not only the skin's surface, but also penetrates toward the inside of the dermis.…”

Laser treatment of acne conglobatа with concomitant oral isotretinoin use

“…The laser treatment plan included (Figure 2): at the first stage, carrying out a course of procedures using a vascular laser Nd:YAP/KTP 1079/540 nm in areas with a tendency to hypertrophic growth on the face and neck; at the second stage, the use of the Er:YAG laser 2940 nm with SMA technology for all types scars. [6][7][8][9] The basic safety principles were applied before treatment, including the mandatory patient examinations every 2 weeks, an initial test for each type of laser exposure in a small area, expansion of the treatment area after confirmation of effectiveness. Four sessions were conducted using the vascular laser with an interval of 2-3 weeks.…”

Facial rejuvenation using Er:YAG laser equipped with a spatially modulated ablation module: A clinical, ultrasound, and histological evaluation

“…We recently described a novel laser for skin rejuvenation, Recovery Spatially Modulated Ablation (RecoSMA), that combines an Er:YAG (2936 nm) laser with a spatial modulated ablation (SMA) module that delivers acoustic wave energy . By delivering laser energy, this device creates zone of microablation in the upper epidermis while with the acoustic‐interference mediated by the SMA module, acoustic waves penetrate the skin depth to 6 mm reaching the dermis/SMAS interface, stimulating neocollagenesis.…”
