Results
The skin thickness of the rear wrists was initially: on right 1.4±0.5 mm,
on left 1.1±0.3 mm.
After the RD it was on right 1.1±0.3 mm,
on left 0.9±0.3 mm (p>0.05).
The skin thickness of the cheeks was initially: on right 1.6±0.2 mm,
on left 1.7±0.5 mm.
After the RD it was: on right 1.6±0.3 mm,
on left 1.8±0.4 mm (p>0.05).
The skin stiffness of the rear wrists was initially: on right 13.9±5.3 kPa,
on left 13.9±3.3 kPa.
After the RD it was: on right: 10,8±2,5 kPa (p>0.05), on left 9,7±2,3 kPa (p<0.05).
The skin stiffness of the cheek was: on right 10.8±0.9 kPa,
on left 10,4±1,2 kPa.
After the RD it was: on right 6.7±0.8 kPa,
on left 8.0±1.3 kPa (p <0.001),
respectively.
Consequently,
the initial values of thickness and elasticity did not have a statistically significant difference for the symmetric zones of the rear wrists bilaterally (p> 0.05).
Similar data without bilateral asymmetry were obtained for the cheeks dermis.
The stiffness of the dermis of the healthy volunteers was consistent with data from other researchers [12,
13].
The thickness of the dermis of the rear wrists and cheeks did not significantly differ after the course of RD from the initial values.
The stiffness of the dermis of the rear wrists and cheeks after a course of RD decreased in comparison with the initial value according to 2D-SWE (p>0,05).
The stiffness of the dermis of the rear wrists and cheeks without bilateral asymmetry were obtained (p>0,05).

The results of the Real-time 2D-SWE of the skin revealed a significant effect of the course of intradermal injection of the HA+SA combination on dermis.
The RD reduced the stiffness of the dermis of the rear wrists and cheeks bilaterally.
This means an increase in the elasticity of the dermis.
