Surprising Ways Smoking Affects Your Looks and Life

Which Twin Is the Smoker?

Maybe there is no fountain of youth, but there is a surefire way to make yourself look older. Smoking changes the skin, teeth, and hair in ways that can add years to your looks. It also affects everything from your fertility to the strength of your heart, lungs, and bones. Take a look at these side-by-side photos. Can you pick out the smoker? Check your pick and get a closer look on the next slide.

Tobacco's Tell-Tale Signs

Twin B smoked half a pack a day for 14 years, while her sister never smoked. The loose skin under her eyes is typical for smokers, according to Bahman Guyuron, MD, of Case Western Reserve University. It's one of several visible signs -- shown on the following slides -- that tobacco byproducts inside your body are harming your appearance. Twin B also got more sun, damaging her skin from the outside, too.

Poor Skin Tone

Smoking chronically deprives the skin of oxygen and nutrients. So some smokers appear pale, while others develop uneven coloring. These changes can begin at a young age, according to dermatologist Jonette Keri, MD, of the University of Miami Miller School of Medicine.  "In young nonsmokers, we don't usually see a lot of uneven skin tone," Keri says. "But this develops more quickly in people who smoke."

Sagging Skin

There are more than 4,000 chemicals in tobacco smoke, and many of them trigger the destruction of collagen and elastin. These are the fibers that give your skin its strength and elasticity. Smoking or even being around secondhand smoke "degrades the building blocks of the skin," Keri says. The consequences include sagging skin and deeper wrinkles.

Sagging Arms and Breasts

Smoking doesn't only damage the appearance of your face, it can also take a toll on your figure. As skin loses its elasticity, parts that were once firm may begin to droop. This includes the inner arms and breasts. Researchers have identified smoking as a top cause of sagging breasts.

Lines Around the Lips

Smoking delivers a one-two punch to the area around your mouth. First, you have the smoker's pucker. "Smokers use certain muscles around their lips that cause them to have dynamic wrinkles that nonsmokers do not," Keri says. Second, you have the loss of elasticity. Together, these factors can lead to deep lines around the lips.

Age Spots

Age spots are blotches of darker skin color that are common on the face and hands. While anyone can develop these spots from spending too much time in the sun, research suggests smokers are more susceptible.

Damaged Teeth and Gums

Yellow teeth are one of the most notorious effects of long-term smoking, but
