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

microdermoabrasion).

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

time.
