If you’re not familiar with Foreo’s suite of Luna devices, here’s a quick run-down: Each device — from the entry-level Luna Play (which is currently $64.35 on Foreo’s site) to the just-dropped Luna 4 — features the brand’s trademarked T-Sonic pulsations and petal-soft silicone bristles to effectively yet gently clean skin. (The brand reports its devices remove 99% of dirt, oil, and makeup residue and are 35 times more hygienic than brushes with nylon bristles.) Depending on the model, you get additional benefits like face-massaging capabilities, vibration patterns or intensities, and app-enabled functions. As someone who’s used many different Luna brushes (most recently the Luna 3 for sensitive skin), I was curious to see what set Luna 4 apart from the pack.
