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.
