"If you touch your eyebrows I will kill you." Although I usually frown heavily upon death threats, when the ultimatum is uttered by eyebrow-expert extraordinaire Jimena Garcia at Robin Evans Skincare Soho, I find myself promising to immediately throw out my tweezers and book consecutive follow-up appointments. This is the type of unquestioning loyalty a lead waxer can inspire. After honing her sense of proportion and symmetry at art school, Jimena dropped out—a chance class with a makeup artist having sent her on a career path whose origins lay in a personal brow obsession harbored since childhood. Now, for over a decade, Jimena has been focusing on shaping New Yorkers' arches. Her mania extends to extracurricular activities at Fresh Cosmetics, where she teaches eyebrow 101 to aspiring aestheticians. With all the talk of big brows being back, you might want to make several appointments to achieve Brooke Shields brows by Thanksgiving. But whatever you do, don't pluck between visits.
