Red Light Therapy (RLT) is a non-invasive therapy that applies specific wavelengths of red and near-infrared light to penetrate deep into a person’s skin and stimulate cellular function. RLT, also called photobiomodulation or low-level laser therapy (LLLT), is commonly used to treat various conditions, such as inflammation, pain, and skin issues. It emits wavelengths of light (usually 600 to 1000 nanometers) that are absorbed by energy-producing organelles in cells known as mitochondria. Here’s what you need to know about the science behind RLT.
It’s worth noting that the frequency and wavelength of RLT treatments vary based on the treatment area. You can also access red light therapy via at-home devices that you can use for a short period daily. Because of the advancement in technology, you can access a wide variety of innovative products that can help you care for your skin from the comfort of your home.
Red Light (620-700 Nm)
A 2006 study revealed that red LED light stimulated collagen production and enhanced fibroblast activity. It resulted in enhanced skin healing and a decrease in wrinkles. Another NASA study discovered that high-intensity red and near-infrared LEDs can quicken the recovery of oxygen-deprived wounds in rats. The Journal of Drugs in Dermatology also published a 2014 report demonstrating that red LED light helped rejuvenate skin tone, texture, and complexion while reducing aging signs.
One frequently asked question about RLT is whether to keep your eyes open or closed during the procedure. According to a 2018 report by the Journal of Physics, researchers evaluated the long-term effects of low-level laser therapy in individuals with age-associated macular degeneration. They also discovered that red LED light therapy can minimize insomnia symptoms and improve sleep quality.
Near-Infrared Light (700-1200 Nm)
A 2008 study outlined the advantages of near-infrared light therapy in skin rejuvenation, anti-inflammatory effects, and wound healing. It also showed that near-infrared LED therapy improved ulcer healing and enhanced skin tissue repair. These studies thoroughly evaluate the existing literature on RLT for dermatologic conditions and provide evidence-based suggestions for its use.
Red Light Therapy Benefits
Generally, RLT has been shown to offer many benefits for skin health, pain alleviation, weight loss, and sleep quality. Such benefits prove this is a promising non-invasive treatment for different health conditions. The following are some of the benefits to expect.
Skin Rejuvenation: RLT can help minimize fine lines and/or wrinkles, promote collagen production, and improve skin texture. It can also improve acne symptoms by alleviating inflammation and destroying acne-causing bacteria.
Pain Alleviation: This non-invasive therapy can help relieve pain and inflammation in different health complications, such as fibromyalgia, carpal tunnel syndrome, and arthritis. Athletes often use this therapy to recover muscle and minimize soreness after extreme workouts.
Weight Loss: RLT can help minimize body fat and encourage weight loss. It breaks down fat cells, boosts metabolism, improves circulation, and induces thermogenesis. Generally, the best results come with a healthy diet and regular exercise.
Improved Sleep Quality: Red Light Therapy may help regulate circadian rhythms and enhance sleep quality, improving overall health.
Improves Circulation: RLT also stimulates nitric oxide production, which can aid in dilating your blood vessels and improve circulation. In turn, this improved blood flow may help supply more oxygen and essential nutrients to tissues, promoting healing and recovery.

Red Light Therapy Side Effects
Modern RLT has numerous positive health advantages and is virtually free of negative effects when applied correctly. However, some risks include mild or extreme redness, dry, itchy skin, hyperpigmentation or blistering. When RLT is used at the right dosage (wavelength) for a specific treatment, skin-related negative effects are extremely rare. So, although this skincare treatment is considered safe, you should discuss it with your healthcare provider or a professional dermatologist before trying it.
