What does 850nm red light do?

Red light therapy has become a popular anti-aging treatment, but with different devices using various wavelengths, it can get confusing understanding what each one actually does. So what does 850nm red light do specifically? let’s dive into the captivating world of 850nm red light therapy! This article covers everything you need to know about 850nm red light therapy for achieving younger, healthier looking skin.

850nm red light

What is red light therapy?

Red light therapy, also called photobiomodulation, uses specific wavelengths of visible red light and near-infrared (NIR) light to penetrate deep into your skin and cells where they trigger a biochemical effect.

Specifically, the light helps boost the production of ATP (adenosine triphosphate), which is the main source of energy for your cells. The light also improves blood flow and reduces inflammation. All of this provides an array of benefits related to skin health, pain relief, wound healing, hair growth, anti-aging effects, and more.

Red light therapy devices use LEDs (light emitting diodes) to deliver the therapeutic light. LEDs allow emitting light at specific wavelengths to target particular cells and tissues.

Understanding Red Light Therapy Wavelengths

Red light therapy utilizes different wavelengths within the red and near-infrared light spectrum. Each wavelength has unique properties and penetrates the body to varying depths. Understanding the significance of these wavelengths is essential for harnessing their specific benefits.

Red light therapy devices use varying wavelengths across the visible red and invisible near infrared spectrums:

Visible Red Light: 630 to 660nm wavelength. Penetrates skin surface to boost circulation and cell renewal.

Near Infrared Light: 750nm to 1200nm wavelength. Penetrates deeper to stimulate collagen and fibroblasts.

Now let’s look more closely at the 850nm wavelength and what makes it unique.

Understanding Red Light Therapy Wavelengths

What does 850nm red light do?

850nm light is a specific wavelength within the near-infrared (NIR) spectrum. The NIR range is from about 700nm to 1000nm.

High absorption by melanin – 850nm light is well absorbed by melanin, making it advantageous for people with darker skin tones.

Increase in cytochrome oxidase – This enzyme plays a key role in energy production. 850nm light boosts the activity of this enzyme.

Low absorption by water & hemoglobin – This allows better penetration through these barriers to reach target cells.

Cellular heating effects – When the NIR light is absorbed by the cells, it causes a mild increase in temperature. This helps improve blood flow and metabolic processes.

Deep tissue penetration – Longer wavelengths like 850nm penetrate deeper into the skin and body than shorter red wavelengths. This allows the light to reach muscles, joints, bones, and even the brain.

So in summary, the characteristics of 850nm light make it optimal for affecting deep tissues and providing cellular benefits related to energy, healing, and anti-inflammation.

Research Proves 850nm Red Light Works

Numerous studies have explored the therapeutic effects of 850nm red light therapy, revealing compelling findings, For example:

– A study in Acta Laser Biology Sinica in 2015 found that 850nm red light therapy can reduce the expression of tyrosinase in melanocytes, thereby inhibiting the synthesis of melanin, thereby achieving whitening effect. [1]

– In a clinical study, patients treated with 850nm red light experienced a significant reduction in pain compared to a control group.[2]

Is 850nm Red Light Therapy Safe?

850nm red light therapy is considered safe when used appropriately. It is non-invasive, non-thermal, and does not produce harmful UV radiation. Just make sure to purchase high quality devices from reputable companies. Still, some reasonable precautions apply:

– Avoid shining light directly in eyes. But aiming near eyes is beneficial and safe.

– Use caution if you take photosensitizing medications or supplements. Discuss with your doctor.

– Start with lower intensities if you have very sensitive skin and build up.

– Allow 48 hours between acid peels or laser treatments before using red light therapy.

– Drink plenty of water before and after use as light exposure can cause mild dehydration.

However, it is essential to follow safety guidelines and consult with a healthcare professional if you have any underlying medical conditions or concerns.

How to Use 850nm Red Light Therapy?

To integrate 850nm light therapy into your skincare routine follow these guidelines:

– Use 5-7 times per week for 10-15 minutes per session. Consistency is important.

– Slowly build up frequency and duration if you have sensitive skin.

– Cleanse and apply serums or lotions before use to boost absorption.

– Hold or position the device close to skin for maximum benefit.

– Move it around to distribute light evenly and avoid skipping areas.

– Target problem spots but also do full face including forehead, cheeks, and neck.

– Protect eyes but aim light directly under and around eyes to improve dark circles and bags.

– Give your skin an occasional 1-2 day break from light therapy.

– Track changes with photos over the first 3 months. Gradual but significant improvements will emerge.

Using your 850nm device correctly is key to getting the best results from each session.
