Fighting hard to retain youthfulness and prevent signs of premature ageing? An extract from the maple tree leaves may help prevent wrinkles, suggests a study.
Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep, the researchers said.
The findings showed that extracts from summer or fall red maple leaves formulated into a powder could be incorporated in skincare products to prevent wrinkles.
“You could imagine that these extracts might tighten up human skin like a plant-based Botox, though they would be a topical application, not an injected toxin,” said Navindra P. Seeram, principal investigator from the University of Rhode Island in the US.
Skin elasticity is maintained by proteins such as elastin. Wrinkles form when the enzyme elastase breaks down elastin in the skin as part of the ageing process.
“We wanted to see whether leaf extracts from red maple trees could block the activity of elastase,” said Hang Ma from the varsity.
The researchers zeroed in on phenolic compounds in the leaves known as glucitol-core-containing gallotannins (GCGs) and examined each compound’s ability to inhibit elastase activity in a test tube.
They found that GCGs containing multiple galloyl groups (a type of phenolic group) were more effective than those with a single galloyl group.
But these compounds can do more than interfere with elastase. In a previous study, Seeram had shown that these same GCGs might be able to protect skin from inflammation and lighten dark spots, such as unwanted freckles or age spots.
And the fact that the extracts are derived from trees would be appreciated by consumers who are looking for natural, plant-based ingredients in their skincare products, the researchers said.
The results were presented at the 256th National Meeting and Exposition of the American Chemical Society (ACS). (IANS)
Yoga face toning may take over botox and face lifting procedures.
27 participants noted changes in their faces after weeks of this experiment.
It is still a matter of discussion if this method can reverse ageing or not.
In his toolbox of Botox, fillers and plastic surgery, cosmetic dermatologist Dr Murad Alam has added a new, low-cost, noninvasive anti-ageing treatment: facial yoga.
Dermatologists measured improvements in the appearance of the faces of a small group of middle-aged women after they did half an hour of daily face-toning exercises for eight weeks, followed by alternate-day exercises for another 12 weeks.
The results surprised lead author Alam, vice chair and professor of dermatology at Northwestern Feinberg School of Medicine in Chicago.
“In fact, the results were stronger than I expected,” he said in a phone interview. “It’s really a win-win for patients.”
Participants included 27 women between 40 and 65, though only 16 completed the full course. It began with two 90-minute muscle-resistant facial exercise-training sessions led by co-author Gary Sikorski of Happy Face Yoga in Providence, Rhode Island.
Participants learned to perform cheek pushups and eye-bag removers, among other exercises. Then they practised at home.
Dermatologists looking at unmarked before-and-after photos saw improvements in upper cheek and lower cheek fullness, and they estimated the average age of women who stuck with the program as significantly younger at the end than at the start.
The average estimated age dropped almost three years, from nearly 51 years to 48 years.
Participants also rated themselves as more satisfied with the appearance of their faces at the study’s end, Alam and colleagues reported in JAMA Dermatology.
“Now there is some evidence that facial exercises may improve facial appearance and reduce some visible signs of ageing,” Alam said. “Assuming the findings are confirmed in a larger study, individuals now have a low-cost, non-toxic way of looking younger or augmenting other cosmetic or anti-ageing treatments they may be seeking.”
The exercises enlarge and strengthen facial muscles to firm and tone the face, giving it a younger appearance, he said.
Happy Face sells instructional worksheets — promising smoother skin, firmed cheeks and raised eyelids — for $19.95. DVDs cost $24.95.
But not all dermatologists are rushing to promote the videos or the exercises.
Dr John Chi, a plastic surgeon and professor at the Washington University School of Medicine in St. Louis, Missouri, said the study raises more questions than it answers.
“The jury is still out on whether or not facial yoga is effective in reversing the signs of ageing,” he said in an email.
Chi, who was not involved with the study, said he would recommend facial yoga to patients who found it relaxing and enjoyable but not for the purpose of facial rejuvenation.
“While the premise of facial exercises to improve the facial appearance or reverse signs of ageing is an appealing one, there is little evidence to suggest that there is any benefit in this regard,” he said.
Chi said facial yoga had not been rigorously examined in peer-reviewed scientific studies. Asked whether procedures such as face-lifts, Botox and fillers had been rigorously examined in peer-reviewed studies, he replied: “Great question. Attempts to do so have been made in the scientific literature with variable levels of scientific rigour.”
Alam agrees that his study raises additional research questions, such as whether the exercises would work for men and how much time people need to commit to doing the exercises for them to be optimally effective. He would like to see a larger study. VOA
