3rd party Clinical Study
14 female subjects aged between 38 to 52 years.
3 times a week for three weeks (a total of 9 sessions per person), their facial muscles (orbicularis oculi, orbicularis oris and major zygomatic) were stimulated so as to obtain visible contraction. In the same sessions, contraction of the following muscles was performed:
- 5 min. each side right and left upper cheek areas
- 5 min. each side of right and left lower cheek and nasolabial fold areas
To ensure that the muscles were always stimulated in the same positions, the unit was applied to the muscles under medical control. The intensity was decided by each patient until she felt the stimulus and caused contraction which the doctor could see.
Ultrasound and photographs were taken right before and after each treatment.
In an ultrasound test, the muscular tissue of a normal subject shows a uniform distribution of echoes at average intensity, with visible parallel striations which make up the muscles tertiary fasciae. The normal average thickness of the zygomatic muscle is 3.5mm.
For accuracy, subject faces were positioned on a chin-rest and the camera tripod was firmly mounted on a table with the same distance and lighting throughout.
