PP New York, NY SN 9780071490627 LK dermatology.mhmedical.com/content.aspx?aid=1172445854 RD 2024/04/19 AB While there remains a good deal to learn about the mechanisms and factors related to intrinsic skin aging, scientists have a stronger grasp of the numerous exogenous factors implicated in the aging of skin, among them sun exposure and lifestyle choices such as smoking, drinking, and poor nutrition. Of course, the internal ramifications of smoking are much better known than are the external results, but more than two decades of epidemiologic research findings indicate that smokers indeed manifest greater facial aging and skin wrinkling than nonsmokers.1 This chapter reviews the literature and discusses what is known about the effects on skin of chronic cigarette smoking.
