Abstract

The viscoelasticity of skin is an important indicator of its healthy condition. However, monitoring the mechanical properties is usually invasive and destructive. In this report, we employed Brillouin microspectroscopy to assess changes of viscoelastic properties of various skin samples. To induce skin injuries, we used the high-power laser irradiation. Brillouin spectra were collected by an earlier developed background free virtually imaged phased array (VIPA) spectrometer. Raman spectroscopy measurements were used to supplement local viscoelastic assessment of skin injuries.
