Beauty products may come and go, but there are 5 key not-so-secret tips to beauty that many of us neglect or simply overlook.  Start with these tried and true beauty rules, and the rest is easy. No, they're not lipsticks, powders, or creams, but they do offer amazing results. 

Water - Let's face it.  Water is truly the ultimate fountain of youth.  It's the sweetest elixir your skin will ever know. Shinier-looking hair, younger-looking skin, get it with a glass of this good old-fashioned stuff. Howard Murad, M.D., associate clinical professor of medicine at the University of California, Los Angeles, and author of The Water Secret: The Cellular Breakthrough to Look and Feel 10 Years Younger agrees. "Water naturally plumps skin, fills in fine lines and wrinkles, and boosts a lackluster complexion.  If your skin is not getting enough water, many physicians warn that lack of proper hydration can cause skin to become dry, tight and flaky. Dry skin is also more prone to wrinkling. "You can look significantly younger just by keeping your skin hydrated," said Murad.  Drink up!

Sleep - There is such a thing as beauty sleep. Shuteye is the key to beautiful skin. A good solid night's sleep lets your skin reboot and restore itself. Lack of proper sleep can cause an increase in stress hormones which can trigger acne, result in dullness, puffiness, and subsequent wrinkles.  Many medical professionals now also recommend sleeping on your back, versus your stomach. Why? Sleeping on your stomach can press your face into the pillow, creating a meshwork of fine lines and creases when you wake up. Who knew your beauty regimen was truly an around the clock process.
