Abstract
Confocal Raman spectroscopy (CRS) enables the real-time profiling of substances penetrating to the skin without sample pre-treatment or labelling. Until now, CRS had been used as a semi-quantitative method, which posed challenges for evaluating topical formulations and assessing bioequivalence. We present a novel approach of CRS for quantitative analysis of skin delivery. The quantitative CRS in vivo has been correlated with the well-established in vitro Franz-diffusion experiments, indicating the potential of CRS for determining skin delivery. We anticipate CRS providing a rapid and non-invasive method that will be an attractive alternative to the clinical studies currently used in bioequivalence testing.
