How deep does red light therapy penetrate?

Red light (wavelength 630nm-640nm) penetrates human tissue superficially, with approximately 80% of the energy being absorbed in the first 2cm. Red light energy has a significant effect on mitochondrial stimulation, which increases the production of ATP and in turn boosts fibroblast activity.

What type of light therapy penetrates the deepest?

How deep does infrared light penetrate the skin?

This explains the relatively large penetration depth of IR -A radiation (780–1,400 nanometres), which can penetrate up to some 5 millimetres into the skin, allowing it to reach the hypodermis and act on it directly.

Does red light therapy penetrate the skin?

RLT is a straightforward procedure involving exposing the body to low wavelength red light. Low-level laser light therapy is another name for the process, though RLT may be more common. This red light is natural and can penetrate deep into the skin, where the cells can absorb and use it.

Does red light penetrate the skull?

[36] used human cadaver heads (skull with intact soft tissue) to measure penetration of 830 nm light, and found that penetration depended on the anatomical region of the skull (0.9% at the temporal region, 2.1% at the frontal region, and 11.7% at the occipital region). Red light (633 nm) hardly penetrated at all.

The science behind the growing trend of red light therapy

Does red light reach the brain?

These are bean-shaped subunits within the cell that put out energy in the form of a chemical known as ATP. The red and near-infrared light photons penetrate through the skull and into brain cells and spur the mitochondria to produce more ATP.

How close to skin should red light therapy be?

For general use, we recommend having the light at a distance of 6-36″ inches away from your body. Closer distances are great for deep tissue penetration. Further distances) are good for treating surface skin issues. For skin issues, we want between 3J-15J per area.

How do you maximize red light therapy?

An easy way to think about it is, the closer you are, the lower the treatment time, the farther you are, the higher the treatment time. One more key variable in getting the most effective dose for your red light therapy treatment is time. Ideally, you want your treatment times to be anywhere from 2-15 minutes.

How long does it take to get exposed to red light therapy?

There is a sweet spot for treatment with red light. The maximum amount of time you should expose your body to this concentrated red light is 15-20 minutes a day.

How far does near infrared penetrate into the body?

The current study showed that the depth of penetration of NIR radiation varies throughout the NIR spectral range in cartilage from 0.5 mm to 5 mm. In region 1 (4000-5000 cm^-1), the NIR depth of penetration was at least ∼1 mm, but approached the penetration limit at 2 mm.

What level of red light is therapeutic?

The range of frequency used in typical red light therapy devices is from 633 nm (a deep red, penetrates the skin and acts on mitochondria) to 850 nm (near-infrared, penetrates deeper into tissue).

How long should you sit under infrared light?

Just 10-minutes a day with a Vital Red Light therapy device is all you need to get the dosage of light that your body requires. Vital Red Light devices treat your body with Red and Near infrared (NIR) wavelengths of light, delivered directly to your skin and body.

What are the dangers of red light therapy?

Even though this type of treatment is generally very safe, negative effects may occur. As a consequence of light therapy, patients can complain of irritability, headaches, eye strain, sleep disturbances, and insomnia. Mild visual side effects are not unusual but remit promptly.

Which light penetrates the most?

Light with longer wavelengths is absorbed more quickly than that with shorter wavelengths. Because of this, the higher energy light with short wavelengths, such as blue, is able to penetrate more deeply.

Which is better red light therapy or infrared?

If you want to treat skin conditions on the surface, Red light LED session is focused and effective. If there is toxicity in the body or stronger metabolic effects are desired, an Infrared session may be the better choice.

Should you wear goggles in red light therapy?

Eye protection isn't necessary, but it can make your experience more comfortable. Exposure to red light does not hurt the eyes. We don't recommend looking directly at the light, but we recommend wearing protective eyewear or closing your eyes during the session. How long does red light therapy take?

Should I put anything on my skin before red light therapy?

Guide to Preparing Your Skin for Red Light Therapy

Treat your skin nicely—avoid irritating your skin with aggressive exfoliant products or sun exposure. Clean your skin with a gentle, non-drying cleanser before treatment to remove any mineral-based sunscreen or makeup containing zinc.

How do I know if red light therapy is working?

Red light therapy has an immediate effect on the body, so you can expect to enjoy some of the benefits of PBMT right away. You might have less pain and swelling in an injured area, for example. You might also notice improvements in your mood after PBMT—you will probably sleep better too!

Can you do too much red light on your face?

What Are the Risks? Red light therapy is generally considered safe, even though researchers aren't exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.

Does red light therapy boost collagen?

Across numerous clinical studies, red light therapy has shown it helps people boost their natural collagen production, without side effects. This leads to a wide range of health benefits, from younger-looking skin, to faster muscle recovery, and stronger joint and skeletal health.

Can infrared light go through bone?

Near infrared light measurably penetrates soft tissue, bone, and brain parenchyma in a formalin preserved cadaver specimen, and also penetrates the full thickness of human cheek in vivo.

Is red light higher or lower energy?

Red light has lower frequency, longer wavelength and less energy.

What is red light therapy pros and cons?

Key Takeaways: Red light therapy is used for skin health, body contouring, mood, brain health, hair regrowth, and pain management. Possible side effects are topical and mostly temporary, including hyperpigmentation and skin sensitivity.

Does red light increase testosterone?

A urologist said later in a viral tweet that there is “absolutely no data on testicle tanning,” adding that it doesn't stimulate the production of testosterone. No, red light therapy isn't a medically approved treatment for increasing testosterone levels.
