Built to go deeper. Red light evolved.
Our bodies evolved to draw healing energy from the sun's red and near-infrared light - to fuel cellular function, support skin repair, and promote overall skin health. The problem is that the sun also exposes us to harmful UV and blue light, which can adversely cause skin aging, pigmentation, and DNA damage.
So FAQ™ has engineered a revolutionary new device: a full-spectrum red light therapy device that mimics the full spectrum of the sun’s natural healing wavelengths - delivering both broad and narrow light wavelengths, while filtering out damaging UV and blue light.
This isn’t just red light therapy. It’s the complete spectrum of skin rejuvenation.
Full-spectrum vs. traditional red light
Traditional red light therapy devices have tried to replicate the benefits we get from the sun, using single LED wavelengths (e.g. 650 nm, 850 nm). And while these wavelengths have shown clinically proven results - their effects are limited. Because the sun doesn’t emit a single wavelength - it delivers a broad, rich spectrum of red light.
FAQ™ 502 is the first at-home device to use both broad-spectrum and narrow wavelength light technologies. This is what allows it to optimize results across multiple skin layers, and at precise depths - just like the sun (without the harmful UV and blue light).

FAQ™ Red Light Peptide Serum

This all-in-one antioxidant-rich serum is enhanced with collagen-boosting Peptides, brightening Sea Daffodil, hydrating HA, soothing Green Tea & repairing Cica helping your skin respond better, recover faster, and look even more radiant after each LED treatment.
