Renuveil · The Science

The science, stated plainly.

What peer-reviewed research shows about red, near-infrared, and blue light — and what we can honestly say about a mask that emits them.

§01 · The Evidence

What the published research shows.

These figures come from peer-reviewed studies of red, near-infrared, and blue light. They describe what was measured in those studies, not results from this device.

630nm · Red
+31%
Increase in measured dermal collagen density reported after 12 weeks of red and near-infrared light in one controlled study.
Wunsch & Matuschka, Photomed Laser Surg, 2014;32(2):93–100
850nm · Near-infrared
4mm
Depth of light penetration into biological tissue, reaching the subcutaneous layer.
Ash et al., Lasers Med Sci, 2017;32(8):1909–1918
460nm · Blue
77%
Of participants whose acne was rated as improved after 5 weeks of blue light sessions in one study.
Kawada et al., J Dermatol Sci, 2002;30(2):129–135
§02 · Documentation

Tested and documented.

Third-party lab reports and regulatory filings, on record.

United States
FCC compliant

Tested to 47 CFR FCC Part 15 Subpart B (Class B) for electromagnetic emissions by an independent laboratory.

Report CTA24072302201 · Jul 2024
Europe
CE certified

Device bears the CE mark, indicating conformity with applicable EU directives for electromagnetic compatibility and product safety.

Declaration of Conformity on file
Materials
RoHS compliant

Components tested and verified free of lead, mercury, cadmium, and other restricted hazardous substances.

Report CTA24072302101 · Jul 2024
Manufactured in an FDA-registered facility (Establishment #3035878914). FDA facility registration is not FDA clearance or approval, and does not indicate FDA evaluation of this device.
§03 · The Three Wavelengths

How light reaches the skin.

630nm · RED

The most-studied wavelength in the category, used in dermatology settings since the 1990s. Reaches mid-dermal depth.

850nm · NEAR-INFRARED

Penetrates deeper than visible light and reaches subcutaneous tissue. The most-studied wavelength alongside red.

460nm · BLUE

Acts at the surface of the skin, at the epidermal layer. Typically chosen for breakout-prone skin.

RED · 630RED · 630
NIR · 850NIR · 850
BLUE · 460BLUE · 460
§04 · The Three Modes

One mask, three programs.

Select a mode with the remote. The mask runs the session and shuts off on its own.

M1 · 630nm + 850nm
Firmness
Red and near-infrared together — the two most-studied wavelengths in the category. Red reaches mid-dermal depth; near-infrared reaches subcutaneous tissue.
Typically chosen for texture and firmness
M2 · 460nm
Clarity
Blue light alone. Acts at the surface of the skin.
Typically chosen for breakout-prone skin
M3 · All three
Full spectrum
Red, near-infrared, and blue in one programmed sequence — the full session, surface to subcutaneous.
The default nightly program
