The Science

Light, explained without the hype. Red light therapy (photobiomodulation) has been studied for decades, tracing back to NASA-funded research on light and tissue. Two wavelengths matter most for skin appearance, and the LUCEN Halo uses both.

 

633nm visible red is absorbed in the upper layers of skin. In clinical studies of LED devices at this wavelength, participants reported improvements in the appearance of fine lines, firmness, and overall tone over 8 to 12 weeks of consistent use.

 

830nm near-infrared is invisible to the eye and reaches deeper than visible red. It is the wavelength most studied for supporting the skin's natural recovery processes.

 

Why irradiance matters: irradiance is the power your skin actually receives, measured in mW/cm2. It is the spec cheap masks do not publish, because low-power LEDs produce a glow, not a result. The Halo delivers at least 30 mW/cm2 at skin contact, and we publish that number because it is the one that matters.

 

What to expect: skin renews on a multi-week cycle. Most users notice subtle changes around week 4 and clearer ones by week 8, which is exactly why our guarantee runs 60 days.

 

LUCEN devices are cosmetic wellness devices, not medical devices. Statements on this page relate to the appearance of skin and have not been evaluated by the FDA. If you are pregnant, photosensitive, or taking photosensitizing medication, consult your doctor before use.
