Smoking is the second most effective way to age skin after sun exposure. Research suggests the skin of smokers over 30 ages twice as fast as the skin of nonsmokers. Indeed, “smoker’s skin” is a diagnostic term used to denote a gray complexion, wrinkles, dilated pores, and failure to heal. Smoking constricts blood vessels, reducing oxygen and nutrient flow, produces a collagendestroying enzyme, and creates wrinkles as lips purse to inhale and eyes squint through smoke. Stop smoking.
