Instead of wasting money on buying miracle creams, you'd probably be better off reading up on these little-known truths about those wrinkles that are giving your age away:

When it comes to anti-aging products, you don't necessarily get what you pay for
Consumer Reports tested seven different popular anti-aging creams, ranging from drugstore brands to high-end department store buys. The results of the 12-week test were modest at best.

Don't blame it on your genes
While heredity does play a role in how we age, dermatologists say the likelihood and the timing at which we develop wrinkles is genetic.  One study involving 200 sets of twins found that while they were "genetically programmed" to age similarly, considerable differences resulting from certain lifestyle habits like smoking and excessive sun exposure did have a major effect on their appearance.

Drinking too much water won't work either
Drinking more water beyond the recommended amount is not a magical solution to erasing those your wrinkles. While dermatologists do say it is important to stay hydrated, there isn't really extensive evidence to show guzzling more water than you need will have any anti-aging effects. At best, it will probably make your eyes look less sunken in. But it's still much better than drinking sugar-loaded sodas and juices, which leads us to...

Sugar levels can affect your skin
A British study found sugar consumption leads to the production of molecules that can age your skin. This occurs when sugar enters your bloodstream, which creates advanced glycation end products (AGEs) that damage proteins like collagen and elastin, which are need to give your skin it's elasticity and fullness. AGEs also attack your bodies antioxidants, making you more susceptible to sun damage.

Reduce your sun
exposure
According to the Environmental Protection Agency, as much as 90 percent of skin aging is caused by sun exposure. One study found that people who used sunscreen regularly were 24 percent less likely to show increased signs of aging. The American Academy of Dermatology recommends you use at least SPF 30 on a daily basis and SPF 50 or higher if you're planning on spending time outdoors, like at the beach or playing sports.

Load up on fruits and veggies
As if you needed more reasons to load up on salad. A 2001 study of people aged 70 and older found those who ate diets rich in vitamins including Vitamin C and E had less photoaging, suggesting the foods they ate had a sort of protective effect. A similar 2007 study of women between ages 40 and 74 found those who had a high intake of vitamin C had fewer wrinkles and less age-related dry skin.

Stop sleeping on your face
Other than getting enough shut eye, sleeping with your face planted in your pillow could also lead to permanent wrinkling. The American Academy of Dermatology warns against side and stomach sleeping. Instead, they recommend sleeping on your back or investing in silk pillowcases (which are also gentler on your hair). The silk fibers can also help your skin retain its moisture overnight.
