The THz response of skin after the application of a commercial skin product. a) The average of 10 measurements of P plotted at different time intervals before and after applying moisturiser to one arm. b) The NRC observed after 25 s of occlusion in three repeats of the same protocol on the same subject after the application of the product, the data point marked for the NRC value before the application is defined to be zero by Eq. 2 and the dashed black line highlights the point for no normalised change observed. In both figures, the error bars correspond to the standard deviation
