Smokers develop more facial wrinkles than nonsmokers and a somewhat grayish skin color. Wrinkles reflect poor production of the protein collagen, a process that requires vitamin C.
Skin color discloses its composition, which is changed by an accumulation of materials from smoke that can be best compared to the stains on smokers' teeth and fingers.
