ABSTRACT
Many skin characteristics can be sampled noninvasively and evaluated ex vivo. D-Squame1, Sebutape1, and cyanoacrylate follicular biopsies (CFBs) are just some examples of sampling techniques frequently employed in clinical testing. D-Squames are used to quantify skin dryness, Sebutapes to determine sebum output, and follicular biopsies are used to evaluate microcomedones. The simplicity and safety of the techniques have rendered these methods very popular.
