While researchers have yet to find the fountain of youth, there are things you can do now in your everyday life to stay youthful--injections, lifts and tucks aside. Ditch these seven bad habits to maintain your youthful, healthy looks longer.
Smoking 
There is not one thing that smoking is good for, especially when it comes to trying to stay youthful and beautiful. (Have you seen those twin study smoker vs. nonsmoker photos? Wow. Nothing gets women to quit smoking like seeing simulated images of how their faces would age if they didn't quit. Every time you smoke one cigarette you’re breathing in toxins and carcinogens that are damaging your organs, including the largest organ in your body: your skin. Not only that, but the repetitive motions you make puckering your lips to smoke forms deep wrinkles around your lips and mouth. Need further evidence to kick your smoking habit for good? If you’re a woman, smoking will cut your life short by 10 years.

Not Wearing SPF
In the fight against wrinkles, not only should you of course avoid tanning, but daily moisturizer with SPF is your number one ally. “Sunscreen applied on a daily basis in the form of an SPF-containing moisturizer or as a separate product is the single best way to promote healthy skin and minimize wrinkling,” explains Dermatologic Surgeon Joseph Sobanko. You need to do this not just in the sunny summer months, but all year round. Harmful UV rays are still definitely present in the winter!

While you’re protecting your face and neck, don’t forget your hands. You should apply a hand lotion with SPF every day (year round) to protect against wrinkles and age spots. Just think of how often your paws are exposed to the elements. You don't want crypt keeper hands.
