FOREO LUNA 4: What to Know
The FOREO LUNA 4 is the most feature-dense device in this lineup, and the specific unit we're linking to is the standard LUNA 4 in the "Balanced Skin" configuration (ASIN B0BFQN4ZH8) rather than the LUNA 4 mini, the LUNA 4 Plus (which adds infrared heat and microcurrent), or the LUNA 4 MEN version, all of which are separate ASINs on Amazon with their own pricing. We picked the standard Balanced Skin unit because it's the closest match to a general-purpose cleansing brush rather than a specialty anti-aging or beard-grooming device.
FOREO builds the LUNA 4 around a soft silicone face, with the company advertising 16 intensity settings split between cleansing and a firming massage mode, including several app-guided routines if you pair it with FOREO's companion app over Bluetooth. FOREO markets silicone touchpoints as dramatically more hygienic than a nylon-bristled brush because they don't have the same porous surface for bacteria to collect in, which is why the brush head isn't designed to be replaced the way a traditional bristle brush head is.
As with every device in this guide, treat FOREO's claims about enhanced product absorption and pore cleansing as the manufacturer's own marketing language rather than an independently verified medical benefit. At the time of this research the listing showed as in stock and shipped and sold by Amazon.com directly, at a premium price point in the neighborhood of $199; confirm the current price on the listing before buying, since FOREO devices do go on sale periodically.
