While getting enough sleep is one of the things doctors recommend in the fight against aging, how you sleep could also make a difference. According to the Bellingham Herald, a Boston-based plastic surgeon says that sleep position can cause individuals to appear older than they are.

"From your 30s to your 50s, how you sleep is important," he told the newspaper. "Certain sleep positions leave sleep lines on your face, which become wrinkles on your face. Sleeping on your side or using a rough pillow can cause sleep lines and wrinkles. Sleeping on your back is the best option, but people find it uncomfortable."

Other steps can also help individuals maintain a youthful appearance, such as remaining hydrated and taking care of the skin. The experts suggests cleansing the skin on the face with a gentle face wash rather than soap and making sure to protect skin from the sun with sunscreen all year long.

"Sun damage causes lots of problems to your skin, not to mention cancerous growth," he told the news source. "Your body can't heal the sun damage unless you give it time to heal, and you can't give it time to heal without using sunscreen."

Besides the face, it's also important to take care of the hands, which can become weathered-looking and wrinkled without proper care, such as moisturizing.

Botulinum Toxin Type A injections such as Botox and Dysport, hyaluronic acid injections, microdermabrasion and chemical peels can help improve the appearance of the skin on the face for a more youthful look.

According to the American Society for Aesthetic Plastic Surgery, more than 7.7 million individuals had non-surgical treatments in 2010. Many choose them because of their affordability as well as the fact that are less invasive than surgery and produce noticeable improvements.
