In vivo skin analysis (INSA) for quantitative determination of lotion transfer to human skin.
There is a need during the development of cosmetic and skin products for simple, quantitative, noninvasive measurements of product deposition onto skin. In this article we describe INSA (in vivo skin analysis) as such a method for measuring the amount of lotion transferred to the skin from tissue products. Using Fourier transform infrared spectroscopy with an attenuated total reflectance (ATR FT-IR) sampling accessory, we were able to quantify lotion levels on the arms of subjects in minutes.
