Foreo Luna 4 Plus Review: T-Sonic Cleansing Meets LED Therapy

What Is the Foreo Luna 4 Plus?

The Foreo Luna 4 Plus is the brand's flagship facial cleansing device, adding an integrated seven-colour LED light therapy panel to the proven T-Sonic vibration technology. T-Sonic delivers 8,000 pulsations per second through the medical-grade silicone touchpoints on the facial side, loosening debris, removing makeup residue, and stimulating circulation. The LED panel adds seven wavelengths — red (anti-ageing), blue (spot treatment), green (brightening), amber (radiance), cyan (tightening), white (clarity), and purple (regeneration) — independently selectable via the Foreo app.

Design and Hygiene

The medical-grade silicone construction is the hygiene differentiator compared to brush-head cleansers. The silicone is non-porous: bacteria cannot colonise the surface between uses the way they can with nylon bristles. There are no heads to replace, no bristles to wear down, and no ongoing consumable cost. The device charges via USB and holds enough charge for 35 sessions — approximately two to three weeks of twice-daily use.

Performance

The T-Sonic pulsations are noticeable but gentle — not the mechanical buzz of some cleansing devices. Post-cleanse skin feels smoother and more even-toned with consistent use. The LED therapy is a genuine addition rather than a gimmick: clinical evidence for red and blue wavelength LED on skin exists, and having it built into a daily cleansing routine removes the barrier of a separate LED mask session. The Foreo app delivers guided routines and tracks session data, though basic use works without it.

Verdict

At £279 (from £379), the Luna 4 Plus is a premium purchase for a committed skincare routine. The combination of clinically-supported LED therapy with proven T-Sonic cleansing in one device is genuinely differentiated. The 71 reviews reflect its relative newness, not a product problem.

Rating: 4.3/5 — A serious skincare tool for those who value the LED addition.
