treatments by aesthetic medicine off the skin.

Elastography of soft biological tissues and organs has broad relevance in clinical
diagnosis and treatment of diseases. Existing characterisation methods for the skin
elasticity are invasive and lack microscale spatial resolution. Here, we use a 3D
probe (16 MHz) of a commercially available ultrasound equipment (Supersonic
Imagine Aixplorer Shearwave) with a large area of elastographic acquisition which
gives us values in kiloPascal (quantitative ) displayed on a color scale from blue
(soft) to red (hard) with qualitative evaluation; furthermore the 3D probe allows to
display the coronal plane which optimally shows the distribution of the elasticity
values in the nearsurface regions of the epidermis. This system achieves conformal
contact with the underlying complex topography and texture of the targeted skin
under static conditions.
We applied this method on human subjects as a tool to evaluate the skin mechanical
properties before and after cosmetic treatments of aesthetic medicine (such as
Our preliminary results on the skin of the face of 10 white women ages 36 75 yrs
old give a mean decrease of stiffness of 23 %.
Conclusions: 3D Shear Wave ultrasound is an effective method to asses quantitative
results of cosmetic treatments by aesthetic medicine and to monitor their effects over
