Effect of Handwashing on Skin Carotenoid Measurements Using Pressure-Mediated Reflectance Spectroscopy.

Study Overview

The purpose of this study is to determine whether the chemicals in soap combined with the friction of handwashing weakens associations between fruit and vegetable intake and skin carotenoid measurements using a pressure-mediated reflectance spectroscopy device. Carotenoids are the red-orange-yellow pigments most commonly found in fruits and vegetables (FV). Humans cannot synthesize these pigments, so they have to get them from eating FV and some of them are absorbed and deposited in your skin.
