AND NOT JUST ON YOUR FACE
SMOKING MAKES WRINKLES ALL OVER THE PLACE.
Mayo Clinic
"The nicotine in cigarettes causes narrowing of the blood vessels in the outermost layers of your skin. This impairs blood flow to your skin. With less blood flow, your skin doesn't get as much oxygen and important nutrients, such as vitamin A. ... As a result, skin begins to sag and wrinkle prematurely because of smoking."
