Spatial frequency analysis of human skin using a photoacoustic microscopy

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.
