Response to comment by Puppels et al. on “A modification for the calculation of water depth profiles in oil‐treated skin by in vivo Raman microscopy”

The presence of penetrated oils in the stratum corneum (SC), oil‐induced occlusion of the SC and formation of occluding homogeneous film on the skin surface are discussed in relation to their influence on results of water profile calculations using conventional and newly proposed extended methods. It is shown that the conventional method does not determine the water profiles in treated skin correctly due to the superposition of Raman bands of SC's proteins and penetrated and remnant oils.
