Abstract
Stimulated Raman scattering (SRS) microscopy enables label-free and quantitative imaging of active pharmaceutical ingredients within the skin, with superior chemical specificity and spatial and temporal resolution. Here, we present a method to study topical formulations on ex vivo human skin using two modalities, SRS and near-infrared light (NIR) transmission. NIR transmission is used to compensate for the SRS signal variance caused by differences in skin thickness and formulation properties. Optical co-registration of the two modalities enables recording the variance in each pixel. The developed method helps to evaluate the cutaneous pharmacokinetics of tretinoin from tretinoin-containing solution and cream formulations.
