What the gurus are saying
Small areas are where this at-home diode laser shines: think eyebrow lines and bikini lines, where reviewers saw hair stop coming back after a few months of sessions. The catch is real, though. It only works on light skin with dark hair, and a built-in lock keeps it from firing on skin that's too dark. Even the happiest reviewers say it's hard to track where you've been, and one still shaves weekly.
