Ready to toss your razor? Unlike IPL and electrolysis, the in-salon Depilar System ($20–$150 per treatment; depilarsystem.com for salons) is painless and works on all skin tones. "It's an enzyme-based gel an aesthetician can apply after waxing to destroy empty hair follicles," says N.Y.C. skin care expert Elke Von Freudenberg. Hair is gone in four to eight treatments.
