In this study, we investigated the optical basis of perceived skin translucency by analyzing subsurface light transport in human skin with depth resolution. Skin optical properties, including absorption and scattering coefficients, were measured using a spatially resolved reflectance method. Monte Carlo light transport simulations were performed using the measured optical properties as input parameters to evaluate the contribution of reflected photons classified by their maximum penetration depth within the skin. In addition, translucency scale values evaluated from skin images of the same subjects were compared with the simulation results. A positive correlation was observed for all skin layers, and the reflected component originating from photons reaching the dermis showed the strongest correlation with perceived skin translucency (Pearson’s r = 0.82).
