A wrinkle, also known as a rhytide, is a fold, ridge or crease in the skin. Skin wrinkles typically appear as a result of aging processes such as glycation, loss of body mass, or temporarily, as the result of prolonged immersion in water. Age wrinkling in the skin is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors.
Wrinkles are a by-product of the aging process. With age, skin cells divide more slowly, and the inner layer, called the dermis, begins to thin. The network of elastin (the protein which causes skin to stretch) and collagen fibers (the major structural proteins in the skin), which support the outer layer, loosen and unravel, causing depressions on the surface. With aging, skin also loses its elasticity, is less able to retain moisture, oil-secreting glands are less efficient and the skin is slower to heal. All of these contribute to the development of wrinkles.

| Is it true that Preparation H really does help reduce wrinkles? |
Lines between the eyebrows (frown lines) and lines jutting from the corner of the eyes (crows feet) are believed to develop because of small muscle contractions. Smiling, frowning, squinting and other habitual facial expressions cause these wrinkles to become more prominent. Over time, the expressions coupled with gravity contribute to the formation of jowls and drooping eyelids.
If your wrinkles bother you, you have more options than ever to help eliminate or at least diminish their appearance. Medications, skin-resurfacing techniques, fillers, injectables and surgery top the list of effective wrinkle treatments.

| Are women the only ones concerned about wrinkles? |
WebMD has listed 23 ways to reduces wrinkles:
1.Avoid the sun.
2.Wear sunscreen.
3. Don't smoke.
4. Get adequate sleep.
5. Sleep on your back.
6. Don't squint -- get reading glasses!

While all of this is factual and interesting (for some at least), what I find refreshingly humorous (but at the same time sad) about wrinkles is the fact that young people cannot “read them” on the faces on the faces of older people.
Having wrinkles adds well, a new wrinkle for young people trying to gauge the emotions seen on older people's faces. A new study suggests that younger people may make more mistakes when judging the emotions of older folks.
To younger adults, age-related changes, such as wrinkles and folds, look like facial expressions, so they may interfere with the perception of emotion in an older face and perhaps convey the wrong message.

In the study, published online in the Journal of Experimental Social Psychology, researchers asked 65 college students to view computer-generated black and white faces. They viewed faces of three men and three women who were young (ages 19 to 21) or old (ages 76 to 83) displaying one of four facial expressions: neutral, happy, sad, or angry.
"In the case of the older expresser, the anger is seen as mixed with other emotions," says lead author Dr. Ursula Hess, a professor of psychology at Humboldt-University in Berlin, Germany. "Clearly it makes a difference whether you think someone is just angry or someone is both angry and sad," she adds.

So how can an older person make their emotions more visible -- and less obscure -- to other people?
Emotions are usually transmitted via a number of channels, including voice and posture, as well as the face, suggests Hess. And during everyday interactions, expressions are more dynamic than looking at a black-and-white photograph in a lab.
Since there are many different sources of emotion information, "an attentive interaction partner could learn how to properly decode the emotion," says Hess.
That's probably why older people are better at decoding other older people's expressions.
