Study of diffuse scattering on facial surface using ray tracing approach.

ABSTRACT: This study investigates the role of topographic attributes in light scattering and diffuse reflection on the skin surface, and diffuse transmission across the surface layer. Validated ray-tracing simulations establish a quantitative link between subvisible micro texture (SMT) and macro texture to skin optical properties, representing youthful and healthy skin characteristics. Our findings reveal the dominant role of the subvisible micro texture parameter ([Formula: see text], the ratio of width to height) in governing light scattering. Smaller ratios, corresponding to fine SMT, result in increased diffuse reflection and create a more pronounced soft-focus effect, which plays a critical role in driving profound skin appearance such as radiance. While the macro texture parameter also influen
