The Science

The Gold Standard: 415nm, 630nm & 830nm

Not all light is created equal. PHOS is engineered around three specific wavelengths — 415nm, 630nm, and 830nm — because those are the three with the strongest independent research behind them. Not a rainbow of underpowered LEDs. Three precise wavelengths. Measurable results.

PHOS devices are engineered around parameters and wavelengths examined in independent dermatological and photobiomodulation research.

415nm — Blue Light

Targeting the Skin Surface & Pores

415nm blue light is widely used in dermatology for its antibacterial properties. It targets C. acnes bacteria on the skin's surface, helping to manage acne-associated bacteria and support calmer-looking skin — without harsh chemicals.

  • Helps manage acne-causing bacteria
  • Supports the appearance of reduced redness associated with breakouts
  • Supports clearer, calmer skin over consistent use

This is the purifying wavelength — ideal for congestion-prone or reactive skin.

630nm — Deep Red Light

Targeting the Epidermis

630nm red light is absorbed by the skin's surface to directly stimulate collagen synthesis, soften fine lines, and improve overall tone and texture — the wavelength most associated with the visible anti-aging effects of LED therapy.

  • Encourages collagen synthesis
  • Improves texture and tone
  • Supports skin renewal and a more even complexion

830nm — Near-Infrared Light

Targeting the Dermis & Hypodermis

Invisible to the human eye, 830nm penetrates deepest into the skin. It reaches the mitochondria — the power plants of your cells — to increase ATP production, supporting cellular repair and the body's natural inflammatory response.

  • Boosts cellular energy
  • Enhances recovery and healing
  • Supports the body's natural anti-inflammatory response

Mitochondrial Activation

At the core of the PHOS experience is Photobiomodulation. When skin absorbs these precise wavelengths, it initiates a cascade of biological responses:

  • Energy Surge — Increased ATP allows cells to repair and regenerate more efficiently
  • Collagen Synthesis — Fibroblast activity is stimulated, naturally plumping skin from within
  • Enhanced Circulation — Improved blood flow delivers oxygen and nutrients to every layer

The Research Behind PHOS

We don't believe in beauty trends. We believe in photobiomodulation — the use of specific light wavelengths to trigger measurable biological change. The following independent studies form the research foundation that PHOS is built on.

415nm (Blue Light)
Clinical research documents blue light's antibacterial effect on C. acnes, the primary bacteria associated with inflammatory acne, reducing breakout frequency and supporting calmer-looking skin over consistent use.

630nm (Red Light)
Targeted for the upper layers of the skin to stimulate collagen production and reduce fine lines. The wavelength most studied for visible anti-aging outcomes in LED phototherapy research.

830nm (Near-Infrared)
Calibrated for deep-tissue penetration, targeting inflammation and accelerating the skin's natural healing response. The 830nm spectrum consistently outperforms standard red light alone in reaching deeper dermal layers.

Independent Research

PHOS devices are designed around parameters studied in the following peer-reviewed research. We invite you to explore the data yourself.

Low-Level Laser (Light) Therapy (LLLT) in Skin: Stimulating, Healing, Restoring — National Institutes of Health / PMC

  • Mitochondrial Activation — Confirmed that red and near-infrared light are absorbed by Cytochrome c oxidase, leading to a direct increase in ATP production at the cellular level.

  • Fibroblast Proliferation — Verified that photobiomodulation triggers the proliferation of fibroblasts — the cells responsible for generating new collagen and elastin fibres.

  • Anti-Inflammatory Response — Observed that these specific wavelengths reduce oxidative stress and inflammation, accelerating the skin's natural healing and repair mechanisms.

A Prospective, Randomized, Placebo-Controlled Study to Semi-Quantify Bio-Stimulatory Effects of 633nm and 830nm LED Phototherapy — PubMed

  • Visible Transformation — After a 12-week clinical period, 52% of subjects showed a significant 25–50% improvement in global photoaging scores, including wrinkle reduction and skin texture.

  • Deep-Tissue Efficacy — Validated that the 830nm near-infrared spectrum reaches deeper dermal layers than standard red light alone, targeting inflammation and cellular repair at the source.

  • Safety & Integrity — Proved that the dual-wavelength approach achieves clinical results with zero downtime, zero pain, and no observed risk of thermal damage under studied conditions.

Phototherapy with Blue (415nm) and Red (660nm) Light in the Treatment of Acne Vulgaris — British Journal of Dermatology

  • Bacterial Reduction — Demonstrated that 415nm blue light targets acne-causing bacteria directly at the source through photo-excitation of endogenous bacterial porphyrins.

  • Clinical Improvement — After 12 weeks, combined blue and red light phototherapy achieved a mean improvement of 76% in inflammatory lesions — significantly outperforming benzoyl peroxide.

  • No Adverse Effects — Confirmed that blue and red light phototherapy produces no significant short-term side effects, making it suitable for sensitive and reactive skin.

Blue-Light Therapy for Acne Vulgaris: A Systematic Review and Meta-Analysis — PMC / Annals of Family Medicine

  • Consistent Evidence — Systematic review of multiple randomized controlled trials confirming blue light phototherapy as a clinically effective, evidence-based treatment for acne vulgaris.

  • Mechanism Confirmed — Verified that 415nm is the peak absorption wavelength for bacterial porphyrins in C. acnes, explaining the specific antibacterial efficacy of this wavelength.

  • Chemical-Free Alternative — Established blue light as a viable alternative to topical antibiotics and chemical treatments, with no risk of antibiotic resistance.
