THE SCIENCE OF LIGHT

Red & Blue Light Therapy — What It Actually Does to Your Skin

A clinical breakdown of how two wavelengths treat two of the most common skin concerns — backed by science, cleared by the FDA.

LED light therapy has moved from dermatology clinics into the hands of women who refuse to compromise on results. But not all light is the same — and understanding exactly what each wavelength does is the difference between a skincare ritual and a clinical treatment.

PART ONE

Red Light Therapy

Red light therapy works at a wavelength your skin can't see but absolutely feels. Operating between 630nm and 700nm, red light penetrates the dermis — the structural layer of your skin — to target the cells responsible for collagen production, cellular repair, and tissue regeneration.

This isn't surface-level skincare. Red light reaches where topical products cannot.

How It Works — Cellular Energy, Amplified

Red and near-infrared photons are absorbed by mitochondria — the energy-producing organelles in your skin cells. This triggers an increase in ATP production, supercharging cellular function. The result: fibroblasts produce more collagen, damaged cells repair faster, and skin behaves the way it did years earlier.

The Alevra LumaMask™ delivers red light therapy across three precision wavelengths — 630nm deep red, 850nm near-infrared, and 1072nm deep near-infrared — working simultaneously to treat the full depth of the dermis.

01 — Stimulates Collagen Production Red light activates fibroblasts — the cells responsible for collagen synthesis — increasing the structural proteins that keep skin firm, plump, and resistant to wrinkle formation.

02 — Treats Fine Lines & Wrinkles By rebuilding collagen at the dermal level, red light therapy treats the root cause of wrinkles — not just their appearance. FDA cleared for full-face wrinkle treatment.

03 — Accelerates Skin Renewal Increased cellular energy speeds the natural turnover cycle — moving damaged surface cells out and replacing them with healthier, more luminous skin faster.

04 — Reduces Inflammation Near-infrared wavelengths carry potent anti-inflammatory properties — calming redness, reducing puffiness, and supporting a more even, rested complexion over time.

PART TWO

Blue Light Therapy

Blue light therapy operates at 415nm — a wavelength with a specific biological target: Cutibacterium acnes, the bacteria responsible for inflammatory acne. Unlike red light, which works through cellular energy, blue light works through photochemical destruction.

The mechanism is precise, the results are measurable, and the science has been robust enough to earn FDA clearance for the treatment of mild to moderate inflammatory acne.

How It Works — Targeting Bacteria at the Source

Acne-causing bacteria naturally produce compounds called porphyrins. When 415nm blue light is absorbed by these porphyrins, it triggers the production of reactive oxygen species — destroying the bacteria from within. The result: a measurable reduction in active breakouts without antibiotics, harsh topicals, or systemic side effects.

01 — Destroys Acne-Causing Bacteria 415nm blue light targets and eliminates C. acnes bacteria at the source — reducing the bacterial load responsible for active breakouts without disrupting the skin's natural microbiome.

02 — Treats Mild to Moderate Acne FDA cleared for the treatment of mild to moderate inflammatory acne — the same clinical designation used in professional dermatology settings, now available at home.

03 — No Chemicals. No Downtime. Blue light treats acne without drying agents, retinoids, or antibiotics — making it suitable for sensitive skin and those who want results without compromise.

04 — Calms Inflammation & Redness Beyond bacteria, blue light has demonstrated anti-inflammatory properties that reduce the redness and swelling associated with active breakouts — visibly calming skin between sessions.

"Two wavelengths. Two cleared indications. One device designed to treat your skin at the clinical level — from the comfort of home." — Alevra Body · FDA Cleared K250830

THE FULL SPECTRUM

All Four Wavelengths

The Alevra LumaMask™ delivers four precision wavelengths — working individually or in combination to address wrinkles, acne, and overall skin health across the full depth of the dermis.

415nm Blue — Destroys acne-causing bacteria. Treats mild to moderate inflammatory acne. 630nm Deep Red — Stimulates collagen production. Treats fine lines and wrinkles. 850nm Near-Infrared — Penetrates deep dermis. Accelerates cellular repair and renewal. 1072nm Deep Near-Infrared — Maximum tissue depth. Anti-inflammatory. Full dermal restoration.

FDA Cleared · K250830 The Alevra LumaMask™ holds FDA clearance for full-face wrinkle treatment and mild to moderate inflammatory acne — two indications, one device, one clearance number. This is the medical standard that separates Alevra from the wellness category entirely.

THE BOTTOM LINE

Why It Matters

The LED light therapy market is crowded with devices that promise results they cannot clinically substantiate. The difference between a cleared medical device and a consumer wellness gadget isn't marketing — it's regulatory evidence.

Red light treats wrinkles. Blue light treats acne. The Alevra LumaMask™ is FDA cleared to do both — at home, in ten minutes, with 96 high-energy triple-chip LEDs and up to twelve sessions per charge.
