Product Overview
Five verified beauty-industry awards and favorable hands-on reviews from Byrdie, Vogue, Allure, The Independent, and Glamour reinforce LUNA 4's reputation for comfortable, customizable cleansing. Its premium price, initial app activation, and nonreplaceable battery are notable tradeoffs, while claims of lasting firming and enhanced skincare absorption remain insufficiently substantiated.
Introduced in 2022, FOREO LUNA 4 refines the brand's silicone-cleansing platform with softer touchpoints, 16 adjustable pulsation intensities, three cleansing modes, and built-in facial massage. The FOREO app adds personalized settings and four guided massage treatments, while everyday cleansing works without the app after initial activation. Its waterproof, easy-to-clean silicone surface requires no replacement brush heads.
Why Plumosity Certified It
Building on the LUNA platform introduced in 2013, LUNA 4 exemplifies the Proven Platform pathway through meaningful generational refinements, thoughtful engineering, and sustained independent validation. Its combination of effective cleansing, extensive customization, and low-maintenance ownership demonstrates the practical value of a mature, well-executed skincare device.

Reviews & Ratings
Customers frequently praise LUNA 4's thorough yet gentle cleansing, smoother-feeling skin, relaxing massage features, and excellent battery endurance. FOREO's customer feedback is overwhelmingly positive, while Amazon reviews are more mixed, citing frustrating app activation, confusing controls, and occasional device failures. Its premium price and limited repairability remain important ownership considerations.
