What Is the FOREO Luna 4?
The FOREO Luna 4 is a silicone facial cleansing device that uses T-Sonic pulsations to dislodge dirt, oil, and makeup from pores. It’s the latest generation of FOREO’s flagship device, featuring a redesigned brush head with softer touchpoints and a firmer side for targeted cleansing.
At $279, it’s positioned as a premium skincare tool — not an impulse buy.
Design and Build
The Luna 4 looks and feels premium. The soft-touch silicone body is satisfying to hold, and the whole unit is waterproof (you’ll use it in the shower). It comes in several colors and the compact size makes it travel-friendly.
The standout feature is the dual-sided design: one side has ultra-soft touchpoints for gentle cleansing and the other has firmer, thicker bristles for deeper cleaning or areas that need more exfoliation.
Battery and Maintenance
FOREO claims 400 uses per charge, and in our testing, this checks out — we charged it once in 8 weeks of twice-daily use. The silicone material is naturally resistant to bacteria, so maintenance is literally just rinsing it after use. No brush head replacements, ever.
How We Tested
We used the Luna 4 twice daily (morning and evening) for 8 weeks, comparing one side of the face using the device and the other using careful manual cleansing with the same products. Photos were taken weekly.
Results
Cleanliness: The Luna 4 side consistently felt cleaner after washing. The difference was most noticeable after wearing sunscreen or makeup — the device removed residue that manual cleansing missed.
Pores: A subtle improvement in pore appearance on the device side, likely from more thorough daily cleansing preventing buildup.
Texture: Slightly smoother texture on the Luna 4 side by week 6, but the difference was minor.
Breakouts: No significant difference in acne between sides, though both improved (likely the consistent routine).
The App
FOREO connects to an app that offers guided routines and skin analysis. Honestly, we found it unnecessary. The device works perfectly with just the on-device button controls. The app feels like it exists to justify the “smart” device label.
Worth $279?
This is where it gets complicated. The Luna 4 does clean better than hands alone. The build quality is impeccable, and it’ll last years. But the improvement over a good manual cleanse is incremental, not transformative.
If you already double-cleanse properly, the Luna 4 adds maybe a 15% improvement. If your cleansing routine is lazy or rushed, the device serves as a good accountability tool that ensures you’re actually cleansing thoroughly.
At $279, we think it’s overpriced for what it delivers. At $100-150, it would be a strong recommendation. Watch for sales.
