A terahertz scanning reflectometer is described herein. A high sensitivity terahertz scanning reflectometer is used to measure dynamic surface deformation and delamination characteristics in real-time. A number of crucial parameters can be extracted from the reflectance measurements such as dynamic deformation, propagation velocity, and final relaxation position. A terahertz reflectometer and spectrometer are used to determine the permeation kinetics and concentration profile of active ingredients in stratum corneum.
