Many people feel that they look better with tanned skin, even though achieving such an appearance may be contributing in the long term to the formation of pigment disorders. In some cultures, such as in Asia, pigmentation concerns outweigh worries about developing wrinkles. Like acne, disorders of pigmentation cause significant stress and embarrassment, so the treatment options should be understood by every cosmetic physician. In this chapter, the mechanisms known to be involved in pigment formation will be explained and the pigmentary conditions most likely to be seen by a cosmetic dermatologist will be discussed. There is a wide array of rare dyschromias that are more pathologic in nature and that are beyond the scope of this chapter. Cosmetic dermatologists are often faced with patients presenting with melasma, solar lentigos, postinflammatory hyperpigmentation, and circles under the eyes. This group of conditions will be focused on here, in addition to some treatment options. Depigmenting agents will be discussed in greater detail in Chapter 33.
