Booking a facial with New York-based skincare expert Cecilia Wong is like trying to hail a cab after midnight on New Year’s Eve—you’d better be prepared to wait. But your patience will be handsomely rewarded. Since 2009, the sought-after aesthetician has relied on holistic, natural, and noninvasive treatments to give her clients the best skin they’ve ever had. From antiaging serums to blemish-busting masks, her eponymous skincare line omits harsh chemicals, relying instead on plants, herbs, and flowers grown on an organic farm in Colorado. In addition to being rigorously nontoxic, all of her products are cruelty-free.
