The most famous cosmetic dermatologist in New York, Pat Wexler is the doctor who smoothes out the creases in the city's most expensive faces.

Bronx-born Wexler left New York for medical school in Brussels, returning to the U.S. in 1979. Four years of work in internal medicine and infectious diseases at Beth Israel followed before she concluded that treating sick people was too depressing. So she headed to Mount Sinai for another residency in the (potentially more upbeat) field of dermatology. Wexler opened her cosmetic dermatology office in the late 1980s, making a name for herself in the early days by treating the city's top models. She's since become one of the best-known dermatologists in town.

Dr. Pat—as she's known to patients and friends—is best known for transferring butt and stomach fat to patients' faces, but she also does the more standard cosmetic treatments like laser resurfacing, chemical peels, vein injections, and Botox. Wexler has recently become a champion of Thermage, a radio frequency machine that tightens the skin. Of course, she wouldn't be a fully-fledged celebrity skin doctor without her name on lotions and potions, so in 2005 she introduced a line of skin care products, which are sold at Henri Bendel, Bath and Body Works, and QVC. Like many of her ilk, she's extremely talented when it comes to self-promotion. The diminutive derm makes regular appearances on shows like Good Morning America doles out free Botox injections to journalists who write about her, and she's even been known to walk around in Wexler-branded t-shirts that promote her practice.

Patricia is married to Eugene Wexler, who quit working as a urologist at Beth Israel to join his wife in her dermatology practice. They have two grown daughters, Perri and Jane. [Image via Getty]
