[ 72 ] • # dayspamagazine • august 2017 in the news Mass A-Peel As clients' search for smoother, younger-looking skin continues, so too does their demand for noninvasive cosmetic procedures; aside from injectables, chemical peels are proving to be the most sought-after option. According to statistics gathered by the American Society of Plastic Surgeons (ASPS), more than 1.36 million chemical peels were performed in 2016, ranking it the third most popular noninvasive cosmetic procedure after Botox and fi llers. Leading global technology research company Technavio also recently reported that the market for chemical peels is expected to grow at a rate of more than 7 percent by 2021, to the tune of $186 million. There are a lot of reasons for the peels' popularity, says Joel L. Cohen, MD, board-certifi ed dermatologist in Greenwood Village, Colorado. "Chemical peels can deliver excellent, visible results for wrinkles, pigment and even acne," he notes. "They can also improve the health and function of the skin." As such, peels are a perfect service to add to spa menus. "The return on investment is high, and many superfi cial peels are appropriate for estheticians to perform," explains Dr. Cohen. "My go-to is PCA Skin's Sensi Peel—it's an excellent choice for all skin types, including darker skin and those who are new to peels. There's no discomfort and basically no downtime after the treatment." A lthough decline of brain function as we age is a common complaint, it doesn't have to be a foregone conclusion. How we take care of ourselves plays a signifi cant role in our brain's ability to function optimally. Some of the latest evidence of this appears online in the British Journal of Sports Medicine , in which researchers analyzed the results of 39 studies to assess the effect of various types of exercise on the brain health of people over 50. Among the specifi c brain functions that the researchers evaluated were overall cognitive ability, alertness, executive function and memory. The types of exercise considered were aerobic, resistance training, multi- component (elements of the former two exercise types), tai chi and yoga. After pooling all of their collection data, the researchers came to the following conclusions: ■ Exercise in general improves brain power in people over 50, regardless of the current state of their brain health. ■ Aerobic exercise markedly enhances cognitive ability. ■ Resistance training signifi cantly affects executive function, and both long- and short-term memory. ■ Limited data does confi rm the previous studies linking tai chi to improved cognition. ■ Exercise sessions of moderate to vigorous intensity lasting from 45 to 60 minutes, at any frequency, are good for brain health. The ongoing growth of beauty and wellness speaks volumes to consumers' quest to achieve their aesthetic ideal. Yet, research into this area's scientifi c basis is a fairly contemporary topic. The Global Wellness Summit (GWS) will highlight this fi eld by tapping three leading experts on the "neuroscience of beauty" as keynote speakers at this year's conference: Anjan Chatterjee, MD ; Lisa Ishii, MD ; and Nancy Etcoff , PhD , are set to present their research and fi ndings on beauty and the brain. Dr. Chatterjee is a professor of neurology at The University of Pennsylvania; chair of neurology at Pennsylvania Hospital; and author and co-editor of numerous neurology and neuropsychology texts. His studies aim to identify why humans fi nd other people or places beautiful. Dr. Ishii is chief quality offi cer for clinical best practices at the Johns Hopkins Health System and senior medical director for clinical integration at the Offi ce of Johns Hopkins Physicians. A practicing plastic surgeon, she also investigates the science behind our perception of beauty. Etcoff is an assistant clinical professor at Harvard Medical School and a psychologist at the Massachusetts General Hospital department of psychiatry, where she heads the aesthetics and well-being program. She created a course in neuroaesthetics at Harvard where she conducts research on the science of happiness, focusing on what people fi nd beautiful in others and why. "Given the massive size of the beauty market and the fact that studies show that people respond at a deep neural level to beauty, it's time to pay attention to the mounting scientifi c research on why we pursue beauty so fervently, rather than continue to dismiss it as a somehow misguided or superfi cial quest," noted Susie Ellis, GWS chairman and CEO. The GWS will be held October 9-11 at The Breakers Palm Beach in Florida.
