What is red light ?

Light is a kind of electromagnetic wave. The entire electromagnetic spectrum includes microwaves, visible light, infrared, ultraviolet rays, and X-rays. They have different wavelengths, wavelengths of general visible light between 400 and 780 nanometers. Visible light is made of red, orange, yellow, green, indigo, blue, and purple 7 different colors. The color is different, the wavelength is also different: the longest wavelength is red light, the next is orange, yellow, green, indigo, blue, purple; that is, the purple light wavelength is shortest. The ultraviolet light and infrared light are located at both ends of the visible spectrum, respectively, belong to non-visible light.

light spectrum

Red light contains visible red light and non-visible infrared light.

The visible red light wavelength is about 600 to 780 nm, which is visible by human eyes. So far, red light is utilized to treat the surface of the human skin.

Infrared light is light outside the visible red band, located on the right side of the visible optical band (non-visible light, the human eye is not visible), the wavelength is longer than red light. Infrared light can be further classified into near infrared, medium infrared and far infrared bands. The entire infrared band is 780 nm to 1 mm. Among them, the near-infrared band is an important band for communication and other industrial usage. The longer the wavelenth, the deeper the penetration to deliver energy to the cells, stimulating healing and relieving pain.

What is red light therapy ?

Red light therapy combines a specific red, infrared light, and LED technology for medical and beauty purposes.

Red light therapy utilizes low wavelength red light and near-infrared light as a treatment means, red light can penetrate our skin, enter the deep skin of leather, and is absorbed by our cells and converted into energy, and can be directly and indirectly Impact and improve cell function. This special type of red light does not cause skin black or skin cancer.

Does red light therapy really work ?

Ever since the initial experiments in space, there have been hundreds of clinical studies and thousands of laboratory studies conducted to determine if red light therapy has medical benefits. At the moment, there’s some evidence to suggest that red light therapy may have the following benefits:

Boosts metabolism
Recharges mitochondria
Stimulates white blood cell production
Reduces body fat
Promotes cell regeneration
Increases energy
Reduces inflammation within the body
Improves circulation within the body
Heals wounds faster

For professional user, commercial or medical usage; we commend to use high power red light therapys devices which ranging from 500w-3000w, so you can get most of the benefits from red light therapy in the shortest time.

How often should you use red light therapy ?

Red light therapy is becoming a popular way for people seeking relief from chronic skin conditions, muscle and joint pain and for those who want to reduce the visible signs of aging. If you’re wondering how often you should use red light therapy for the best results, the short answer is that there is no one-size-fits-all solution. But most people get good results with a 15-minute daily session 3-5 times per week for several months.

Red light therapy is very safe, and rarely has any side effects. Still, we recommend a slow introduction to determine what will work best for you.

General Skin Care and Anti-Aging Purpose

Use red light to improve skin tone, minimize the effects of aging, and heal sun damage in 10-20 minute per time, 3-5 times weekly for 1-4 months. This will help you increase collagen production and improve collagen density, eliminate fine lines and wrinkles, and clear up general skin issues. After your skin tone and overall health has improved, maintenance therapy using shorter and less frequent sessions will ensure lasting results.

Muscle Healing

Use red light for upper limb muscles; near infrared light is more beneficial for the larger leg and core muscle groups. Use red or NIR therapy alone or in combination for 3-5 minutes immediately prior to exercise to precondition the muscles and prevent injury. Immediately after exercise, bathe muscles in red or NIR light for 10-20 minutes to accelerate recovery. A maintenance program of pre-exercise and post-exercise light therapy may promote optimal physical performance.

Hair Loss

Use a combination of red light (660nm) and near-infrared light (850nm) for 10-20 minutes per time, 3-5 times per week to stimulate the hair growth. After 1-4 months, decrease the frequency to 1-4 times per week to continue to stimulate hair growth over time.

Arthritis and Joint Pain

One study found great results for red and NIR light for sufferers of degenerative osteoarthritis. These participants used it for 15 minutes, twice a day, with great results, so that’s likely your best starting point. To ease pain and slow the progression of rheumatoid arthritis or osteoarthritis, continue with red or NIR therapy indefinitely as a twice-daily regimen, or as shorter and less frequent sessions depending on your level of pain.

Chronic Skin Disorders

Red light is used to treat rosacea, acne, eczema, psoriasis, and other chronic skin conditions. The American Academy of Dermatology recommends treating chronic skin conditions with the guidance of a medical professional who will guide you in the optimal intensity of red light therapy depending on the severity of the condition.

Many chronic skin conditions have no known cure, so the best approach involves consistent red light exposure to minimize symptoms and promote healthy skin growth. In general, you can use red light for 10-20 minutes per time, 3-5 times a week for 1-4 months, and continue with a maintenance program as recommended by your dermatologist.

Skin Wounds and Scars

For skin wounds, stretch marks, and mild scars, 10-20 minute red light treatment per time, 3-5 times per week for 1-4 months will stimulate collagen production and reduce the appearance of scars. No follow-up treatments are needed, although deeper scars may require longer-term treatment.
