Lately, everyone seems to be talking about red light therapy. All the potential benefits and the incredible results they’re experiencing. Red light therapy has garnered a lot of attention for it’s exciting applications across various beauty and wellness domains.
We’ve published, “The Best Red Light Therapy Guide,” to help you explore the most up to date applications, and scientific evidence supporting the efficacy and amazing benefits of red light therapy.
What Is Red Light Therapy?
Red light therapy, also known as low-level laser therapy or photobiomodulation, is a non-invasive treatment that utilizes specific wavelengths of red and near-infrared light to stimulate cellular function.
Red light therapy, which was originally developed to aid in wound healing and tissue repair for astronauts, has grown in popularity, due to it’s potential phenomenal benefits for skincare, pain relief, and overall wellness.
Red light therapy works by delivering wavelengths of light that penetrate into the skin’s surface and reach the cells below. Once absorbed, these light waves stimulate the mitochondria, the powerhouse of the cell, which then increases it’s production of adenosine triphosphate, a molecule that provides energy to power cellular processes.
This increased ATP production enhances our cells function, promoting faster cell repair, skin regeneration, and reduced inflammation.
This cellular boost can lead to younger looking skin though increased skin elasticity, skin vibrancy, decreased appearance of fine lines, and a reduction in acne, acne scars, and inflammation.
In addition to it’s cosmetic applications, RLT is widely recognized for it’s potential benefits in reducing pain and inflammation, especially in conditions like arthritis and muscle soreness.
By modulating inflammatory pathways and improving blood flow to targeted areas, red light therapy has shown promise in supporting recovery for athletes and individuals with chronic pain.
Red light therapy is delivered using a red light device, from handheld gadgets to larger panels which save time and are usually more powerful and effective. Check out our favorite clinically proven red light therapy panel here to utilize all the benefits of red light therapy at home.
Safety is a key benefit of RLT. Because it’s non-invasive, painless, (a red light therapy session is actually very relaxing and you feel good after) and has minimal side effects when used appropriately.
