Introduction
Recently, esthetic medicine has been gaining its momentum worldwide, mostly due to the development of minimally invasive techniques. In our opinion, elastography can be a candidate for an objective quantitative method to evaluate facial skin condition. The aim of this study was to determine intra-rater reproducibility of shear wave elastography (SWE) in the evaluation of facial skin in patients qualified for minimally invasive nonsurgical facial rejuvenation treatment.

Aim
To determine intra-rater reproducibility of shear wave elastography (SWE) in the evaluation of facial skin in patients qualified for minimally invasive nonsurgical facial rejuvenation treatment.

Material and methods
The study included 57 women between 40 and 67 years of age (mean: 51.5 ±7.3 years). Prior to the laser treatment, all participants were subjected to ultrasonographic examination and elastography of the skin. Upon visualization of the area of interest, the thickness of the dermis, subcutaneous tissue and superficial muscular aponeurotic system (SMAS) in millimeters was measured. Then, SWE was performed.

Results
No statistically significant differences were found in intraclass coefficient values (ICC) for elastographic parameters of the skin on the right and left side of the face (0.953 ±0.001 vs. 0.953 ±0.001, p = 0.992). Moreover, no significant differences were observed in the ICC values for the SWE parameters of various skin layers: dermis, subcutaneous tissue and SMAS (0.945 ±0.001 vs. 0.953 ±.001 vs. 0.961 ±0.001, p = 0.597). Women with normal body weight and overweight did not differ significantly in terms of their elastographic parameters of facial skin.

Conclusions
Shear wave elastography is a reliable method for the evaluation of facial skin elasticity, providing highly reproducible results in all patients, regardless of their age and body weight.
