Facial Aging Is More Than Skin Deep and others on ScienceDaily

0 comments


I like reading Science Daily, they are posting a lot of good articles about the latest scientific studies in various fields including Health & Medicine, Facial rejuvenation, Skin Care, Healthy Aging. They have freely accessible research articles, book reviews, educational videos... Highly Recommended !!

Facial Aging Is More Than Skin Deep



ScienceDaily (Mar. 23, 2010) — Facelifts and other wrinkle-reducing procedures have long been sought by people wanting to ward off the signs of aging, but new research suggests that it takes more than tightening loose skin to restore a youthful look. A study by physicians at the University of Rochester Medical Center indicates that significant changes in facial bones -- particularly the jaw bone -- occur as people age and contribute to an aging appearance.


Presented at the American Association of Plastic Surgeons annual meeting in San Antonio, Texas on March 23, and published in the Journal of Plastic and Reconstructive Surgery, the study suggests that the future approach to facial rejuvenation may be two-fold, first restoring structure underneath before performing skin-tightening procedures.

ScienceDaily (Oct. 23, 2007) — A team of Johns Hopkins scientists reports in the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation -- the most abundant cancer-causing agent in our environment -- by topical application of an extract of broccoli sprouts.

Vitamin A Helps Reduce Wrinkles Associated With Natural Skin Aging


ScienceDaily (May 22, 2007) — Applying vitamin A to the skin appears to improve the wrinkles associated with natural aging and may help to promote the production of skin-building compounds, according to a new report.
The wrinkles and brown spots associated with aging appear first and most prominently on skin exposed to the sun, according to background information in the article. "Human skin not exposed to the sun also ages but less dramatically," the authors write. "In intrinsic, natural or chronological aging, skin loses its youthful appearance by becoming thinner, laxer and more finely wrinkled. These changes are readily appreciated by inspecting the upper inner arm." Thinner skin results from a reduced production of the protein collagen and may slow wound healing, presenting a public health issue. "Safe and effective therapies to reverse the atrophy of natural skin aging do not exist currently," the authors note.

New Fat-Based Anti-Wrinkle Lotion Slows Down Aging of Skin, Study Shows

ScienceDaily (June 6, 2008) — Topical applications of a naturally occurring fat molecule have the potential to slow down skin aging, whether through natural causes or damage, researchers report.
Through both the normal aging process and external factors like UV damage, smooth, young skin inevitably becomes coarse and wrinkled. The basis of this wrinkling is that time and damage both lower the production of new collagen while increasing the levels of enzymes called MMPs that chew up existing collagen.



Covering up, slowing down, or even stopping the wrinkling process has become a big business, and as part of this research endeavor, Jin Ho Chung and colleagues tested seven naturally occurring lipids (greasy molecules that play many important biological roles) in their ability to reduce skin aging.
