Physicists Find Clues to the Evolution of Wrinkles

Researchers at the University of Massachusetts, Amherst have been studying the evolution of wrinkles in a recent dermatological study, and have published several papers in the current issue of Physical Review Letters about their findings. Scientists are attempting to understand the formation of wrinkles in biological tissue, and looked at how wrinkles in a sheet adapt to an edge that tends to be flat.

In a related study, researchers looked at the transition from soft wrinkles to sharper folds, and proved that folds in the tissue, like the edges of a neatly made bed, strain the sheet and help to smooth out wrinkles.

Physicists are looking primarily at the superficial causes and effects of wrinkle formation, but for many years, researchers have also taken a close look at the effects of toxins in the environment, the role of antioxidants in the diet, and the effects of various skin care products in the formation of wrinkles. Many experts suggest that wrinkle formation is largely the result of genetics and lifestyle factors, such as smoking, diet and exercise.  Wrinkle treatments such as laser skin resurfacing and skin rejuvenation procedures can help to reverse many of the signs of aging.

Individuals who spend a lot of time in the sun do increase their risk of getting wrinkles because UV rays can break down collagen in the skin which makes the skin weaker. Overexposure to the sun can cause premature wrinkles around the eyes, mouth and nose, and also increase the chances of skin cancer.

Some experts suggest that a balanced diet that contains a high concentration of antioxidant-rich foods can also ward off wrinkles and improve the skin’s appearance. Foods that are high in antioxidants may help to increase the firmness of the skin and increase skin elasticity. Some foods that are high in antioxidants and also contain iron can help bring oxygen to the skin and prevent premature aging.

  • Cosmetic surgeons that specialize in rhinoplasty and other aesthetic enhancement procedures often use specialized tools to ensure a more precise surgery. A recent study shows the benefits of an ultrasonic aspirator for rhinpolasty procedures.

  • Many cosmetic surgeons and medical spas offer hyaluronic acid gel-based fillers such as Restylane and Juvederm for filling out wrinkles and lines, and use them for the “liquid facelift” procedure. A new development announced at the American Society of Plastic Surgery annual conference, Plastic Surgery 11 THE Meeting in September 2011 is a solid – not gel – hyaluronic acid filler that is instantly reversible. This filler may offer a more precise correction of wrinkles and lines than gel-based fillers, and is an exciting development in the field of minimally-invasive plastic and cosmetic surgery.
