Study for skin gloss perception using computer modulation and frequency separation on surface reflection.

We identified four different factors related to perceiving matte, glossiness, and greasiness on the faces of Korean women, including the LFM and HFSD of surface reflection, as well as the number of highly glossy objects and the area of surface reflection. Furthermore, we identified evenness of shine as a key factor for the perception of greasiness. These parameters could be useful for distinguishing skin gloss and for a quantitative evaluation of greasiness.
