Many unique body areas require consideration. The face can be considered as a whole; however, the eyelids and the lips represent unique facial areas that demand separate

The abundant sebaceous glands and terminal hair follicles on the scalp make this a separate skin environment, along with skin that expands and contracts with movement in intertrigenous areas such as the neck and the underarms. The female and male genitalia are also unique with numerous glandular and follicular structures that present a hygiene challenge.
