How we tested
I used the LUNA 4 MEN twice daily for three weeks alongside a standard gel cleanser. Tests covered performance on stubble and short beards, skin irritation, cleansing efficacy (oil and dirt removal), ease of cleaning and battery life.
Performance
The device does what it sets out to do very well. On bare skin it removes daily grime efficiently and leaves skin feeling noticeably smoother; on bearded areas the larger massage zones are gentler and avoid tangling with facial hair. There's a clear improvement in how moisturisers and serums absorb after use -- products sit in rather than sit on skin. The T‑sonic pulses feel reassuringly firm without being abrasive, and intensity is easy to adjust via the phone app or the device controls.
Battery & build
Battery life was excellent -- more than two weeks with twice-daily use. The USB‑C charging is modern and reliable. The silicone body is solid and stain-resistant; it rinses clean and dries quickly, which beats brush heads that trap muck. App pairing is useful for custom programmes, though some will find toggling the phone into the routine unnecessary.
Who it's for
This is for men who care about skin health and can justify the outlay for a tech device. If you've got sensitive skin or short stubble, the LUNA 4 MEN is safer than bristled brushes. If you're on a tight budget, a simple cleansing gel and manual wash will do fine -- the LUNA is an upgrade, not an essential.

Final thoughts
FOREO's LUNA 4 MEN is a smart, well-built cleaner that genuinely helps with skin prep and product performance. For men who already invest in grooming and dislike fiddly brush heads, it's a worthwhile upgrade. For price-conscious users, consider whether the extra convenience and marginally better results justify the spend.
