There are anatomic site differences in relative absorption: forearm = 1, back = 1.7, sole = 0.14, palm = 0.83, scalp = 3.5, cheek = 13, eyelid and scrotum = 42. A multitude of additional factors must be considered, including: chronicity of disease being treated, percentage of body surface involvement, patient age, specific medication, vehicle, frequency of application and technique, potential side effects, presence of coexisting factors, and cost. Importantly, if the product is unpleasing, patient compliance may be compromised.
