Clinical Parameters Involved in Skin Tone Perception of Asian Population

This study reveals the correlation of skin yellowness perception and clinical parameters, especially the contribution of relevant colorimetric parameters. From a third-person perspective, b*, L* and diffused reflection are key determinants of perceived skin yellowness. The observed seasonal variation in yellowness perception indicated a perceivable "seasonal skin yellowing." The findings provided new insights for developing treatments for skin aging yellowness, photoprotection and modulation of colorimetric parameters (L* and b*) and optical parameter (reflection) are highlighted as important clinical targets.
