What Is Red Light Therapy Wavelength?

Frequently Asked Questions

What Is The Optimal Wavelength For Red Light Therapy To Be Most Effective?

What is the optimal red light therapy wavelength to be most effective?

Various wavelengths have unique purposes. The commonly used treatment wavelengths include 660nm and 850nm which are now known to be the best for different treatments. Go for devices approved by the FDA containing both wavelengths.

To what extent do they cover a specific wavelength of energy like Red Light Therapy?

Low-level laser therapy (LLT) or PBM refers to the medical use of red light which is wavelengths range between 600-1000 nm and absorbed into the mitochondria of the cells and boosts their activities.

How Long Does Red Light Therapy Penetrate Into The Skin?

The light intensity and its wavelength affect the depth of penetration into the skin. Eight to ten millimeters deep into the dermis the red light will interact with the cells. NIR has a reach of up to about 2.5 centimeters. These rays may also pass through muscles, bones, or deep fleshy tissues. The depth of acne scars also depends on one’s skin and if there are any skincare products.

What Is Red Light Therapy?

These are wavelengths of light that are not intense as they treat skin problems, joint pains and inflammation commonly termed Red Light Therapy. It is a process that involves piercing through the skin to initiate the growth of elastic and collagen fibers needed for healthy skin and tissue. Red Light Therapy offers a natural solution without pain or any invasive measure hence the reason why most people have embraced this method of treatment. The wavelength of red light comprises one of the bands of the spectrum. Your choice of the best wavelength is based on the condition being treated as well as your particular plans. There are certain wavelengths and some ranges of wavelengths that are believed to have some unique healing effects.

Where Does Red Light Therapy Sit In The Spectrum?

What Is The Spectrum Of Red Light Therapy?

Red light forms the initial end of the spectrum for RLT and it progresses upstream to NIR which further gives way to Infrared Light.

  • Red Light: Deep red (630-660nm) boosts collagen and circulation for anti-aging skin rejuvenation. Red (600-700nm) pairs well with near-infrared to powerfully reduce muscle and joint pain.
  • Infrared Light: Infrared(900-1400nm) is used to treat traumatic brain injury, such as Alzheimer’s disease, and other Neurodegeneration, as well as to enhance the effectiveness of cancer chemotherapy. It is usually used only in severe cases and not in conventional red light therapy.
  • Near-Infrared Light: Near-infrared (760-1000nm) penetrates 3-4cm deep for regenerating tissues like nerves, bones, and organs. NIR light(800-880nm) demonstrates the highest healing potential within its range.

What Are These Wavelengths Dedicated To?

While red light therapy encourages general cell health, certain wavelengths dominate for indications:

  • Acne: 660nm disinfects the skin and debris for clearer complexions.
  • Eczema: 660nm and 850nm together soothe inflammation and rebalance skin.
  • Hair Growth: 660nm and 850nm stimulate follicles dormant from stress or aging.
  • Pain: 850nm penetrates joints for lasting muscle relief.
  • Wound Healing: 660nm and 850nm work wonders on injuries inside and out.
  • Neurological: 850nm may even reverse cognitive decline over time with consistent use.

What Is The Most Common Wavelength?

While protocol diversity abounds as research blossoms, a few workhorse wavelengths stand out based on existing commercial products and clinical experiences:

  • Deep red/red at 660nm: Anti-aging, pain, wound healing generalist with excellent penetration and safety profile.
  • Near-infrared at 850nm: Heavy-hitting deep tissue revitalizer well-suited to muscles, injuries, and neurological indications.
  • Mixed red+NIR “full spectrum” devices: Multipurpose all-rounders combining 660nm and 850nm for the balance of skin-deep and deep treatments.
  • Infrared at 905nm: Another muscle and joint pain champion, often used alongside 850nm in combo therapy.

Popular devices focus on deep red, NIR, or balanced full spectra as core prescriptions, then allow targeting added wavelengths like 660nm red or 655nm red/NIR combo for specialist needs. Flexibility and simplicity drive broad at-home accessibility.

Devices For At-Home Red Light Therapy

Many of the devices you can buy can be used in the comfort of your own home, including:

  • Panels: There are many sizes of panels to choose from, full-body panels can cover the whole body, and small panels can be used for more targeted local treatment.
  • Hand-Held Devices: Handheld tools offer portability that is most appropriate for targeting very specific bodily locations.
  • Masks: These products are primarily used for anti-aging (reducing wrinkles, and bags under the eyes, sun protection, and improving skin tone) and to treat acne, rosacea, cold sores, and other facial skin problems.
  • Belts: Apply to the waist pain and soreness, waist wrap can also relieve dysmenorrhea and other conditions.
  • Blanket: A red light blanket is a great back red light therapy (for back acne, relief of back pain, or any other back issues), etc.

What About Blue Light Therapy?

While blue/violet wavelengths near 415nm activate antibacterial and circadian signaling effects, they lack red/NIR’s deep penetration and tissue-stimulating abilities.

Only low-level blue is safely used in combination treatments, as 415nm alone can potentially damage live cells through oxidative mechanisms at higher doses.

It works best partnered with safer red/NIR light cocktails for targeted acne zap. Or as a mild wake-up tool focused on the upper body/face before sunrise-simulating desk lamps.

Used judiciously under medical oversight, blue light provides complementary niche roles. But red and NIR shine as true heavy-lifting workhorses for inner healing and regeneration through deep photobiomodulation.

Scientific Support For The Effectiveness Of Red Light Wavelengths In Specific Applications

By now you’ve glimpsed photobiomodulation’s colorful healing potential. But have decades of scientific scrutinizing backed these claims? Let the evidence illuminate!

  • Pain: Meta-analyses confirm red and NIR significantly reduce both acute and chronic muscular/joint discomfort.
  • Wound Healing: Clinical trials showcase accelerated closure rates, collagen deposits, and angiogenesis from 660nm and 850nm protocols.
  • Acne: Randomized controlled studies give 655nm nods for reducing lesions and 660nm for antibacterial/anti-inflammatory effects.
  • Hair Growth: Multiple investigations link specific red/NIR wavelengths to stimulating follicular keratinocyte proliferation and growth factors.
  • Neurological: Research associates NIR and mixed spectrum light with reversing cellular biomarkers of neurodegeneration and improved mood/cognition.
  • General Health: Red light boosts mitochondrial function, immune cells, and antioxidant activity in human and animal models.
