In addition, sebum supplies lipids to the surface of the epidermis that may aid in preventing transepidermal water loss (TEWL) (see Chapter 11). Excess sebum production produces oily skin, and in many cases, contributes to acne. With continuing advances in understanding the physiology and molecular biochemistry of sebaceous glands (SGs) and lipid metabolism, dermatologists may soon be able to elucidate the underlying aspects of sebum secretion and oily skin. This chapter will focus on the various known causes of oily skin and their implications, a new classification approach for determining the oily skin type, and the available treatments for oily skin as well as the efficacy of these treatments.
