Red light therapy (RTL) is rapidly becoming one of America’s favorite treatments. From red light masks, to red light in your average nail salon, to the actual powerful red light therapy of a doctor's office - people are ready to try something new. There are so many benefits of RLT from improving your skin’s health, scalp stimulation with hair growth, the improvement of acne, the improvement of psoriasis, and even as a stress reliever.
This treatment uses wavelengths of red and near infrared light to penetrate the skin, which is when it energizes cells, enhances circulation and stimulates that skin repair process. The secret of RLT is stimulating cellular energy production. When the light is transmitted in the 630-850 nanometer range, it is absorbed by the mitochondria, which increases the production of adenosine triphosphate.
This intricate process increases energy output and assists cells to repair damage more effectively and rapidly, resulting in better skin health - reduced inflammation, faster tissue regeneration, the lot! Different wavelengths penetrate the skin at different depths:
- Red Light (630-660 nm): Primarily affects the skin’s surface, promoting collagen production and reducing wrinkles.
- Near-Infrared Light (810-850 nm): Penetrates deeper into tissues and muscles, reducing inflammation, enhancing blood flow and accelerating healing.
This dual-action makes red and NIR light therapy an ideal treatment for skin improvement and overall skin health. Let’s discuss the benefits of RLT and why it is so useful for skin health, reducing inflammation, chronic pain and more.

The Benefits & Uses of Red Light Therapy
Collagen is the primary protein that keeps skin plump, tight and youthful. Unfortunately, as we age, collagen production declines, leading to skin sagging, lines and of course wrinkles. Red light therapy has been researched and proven to improve the look of skin’s aging by stimulating the fibroblasts (the cells responsible for making collagen and elastin). The particular study done in 2014 by Photomedicine and Laser Surgery found that red and NIR light therapy significantly improved skin complexion, elasticity and collagen density in participants after 30 treatment sessions.
For those who struggle with acne and skin inflammation, red light therapy is another sound choice. RTL reduces inflammation, bacteria that causes acne, and fights excess oil production. Unlike harsh topical treatments, RLT promotes this skin healing without dryness, redness or irritation.
Hair loss affects millions of people worldwide, and red light therapy has been proven to stimulate hair regrowth by revitalizing hair follicles. RLT actually stimulates the microcirculation of the scalp, which is believed to increase nutrient delivery to the hair follicles, assisting them in activating the growth phase.
RLT also reduces inflammation, as we previously discussed, which can also be a cause of hair loss or slow hair growth. The science that backs these claims was done in 2017 by Lasers in Surgery and Medicine, which discovered that men and women with androgenic alopecia (pattern baldness) experienced a 39% increase in hair density after 16 weeks of red light therapy treatments (650 nm wavelength). Red light therapy enhances keratin production, strengthening hair strands and reducing breakage.
Red light is also beneficial for those who struggle with joint pain or arthritis. These light wavelengths help reduce oxidative stress and improve mitochondrial function. A study done in 2016 by The Journal of Biophotonics found that athletes using red light therapy experienced 40% faster muscle recovery and less soreness after workouts.
Studies also show that red light therapy can actually improve mood; now that is amazing! Red light therapy regulates melatonin production, improving sleep quality and reducing stress. A 2012 study in The Journal of Athletic Training found that red light therapy significantly improved sleep duration and quality in athletes suffering from insomnia.
Red Light Therapy Options
Now that we understand all the benefits of red light therapy and how it works, let’s discuss the RLT options. Red light therapy is offered in wellness facilities, spas, doctor's offices and more. It is best to ensure that the red light device you are using is properly administered and regulated. At Aesthetic Skin Chicago, the office has a powerful red light device frequently used by patients.
A red light mask is also a great option. Red light masks ensure even light distribution, including the neck. Using a red light mask is also easy and convenient, leaving your hands free. If you purchase a red light therapy mask, it is best to follow the guidelines and instructions included in the packaging, but for best results, it is important to stay consistent with treatments.
What to Look for in a Red Light Therapy Device
- Clinically Proven Wavelengths: Ensure the device emits light at 630-660 nm (red) and 810-850 nm (NIR).
- FDA-Cleared Devices: Devices with FDA clearance have been tested for safety.
- Medical-Grade LED Power: Look for at least 100 mW/cm² power output for effective penetration.
- Trusted Manufacturer: Buy from doctor-recommended brands or medical offices to ensure quality and safety.
The advancement in technology in the beauty and wellness industries is astonishing. Many are eager to find new ways to boost their personal wellness, or simply to give their skin the best treatments available. Red light therapy is one of the fastest growing treatments, and with science backed power, this is a game changer for spa and wellness pros to include in their services.
