Spatial frequency analysis of human skin using a photoacoustic microscopy

24 January 2022 • 5:30 PM - 7:00 PM PST | Moscone West, Lobby (Level 3)

Abstract

To evaluate photoaging (damage to elastic fibers in the upper layer of the dermis), photoacoustic images of human skin (25 μm thickness, Kligman criteria G0-G4) sections were obtained. After the upper dermis of these sections was measured using acoustic resolution photoacoustic microscopy (AR-PAM) at visible light region wavelengths, spatial frequency analyses of the upper dermis were conducted. Results clarified that in the early stage of photoaging, high-frequency components increase as photoaging progresses. These analyses demonstrate the feasibility of early diagnosis of photoaging using PAM.
