Red light therapy (RLT) is a procedure in which light-emitting diodes (LEDs) are used to treat medical and cosmetic conditions. It sends low-intensity red and near-infrared light to body cells to stimulate healing. This non-invasive, painless, and heat-free treatment aims to solve skin problems by using low-wavelength red light. Experts believe that this therapy helps cells repair and become healthier by stimulating the mitochondria, sometimes called “energy generators” of cells.
It can improve scars and signs of aging, such as wrinkles, by acting on fibroblasts, which are skin cells responsible for the production of collagen. RLT and ELT (extracorporeal light therapy) are large surface and full body treatment modalities for skin rejuvenation and improvement of skin feel and complexion. A review in the European Journal of Physical and Rehabilitation Medicine compiled the results of many studies on RLT and musculoskeletal disorders. It found that this therapy can be beneficial for people with alopecia, as well as those with sports injuries.
However, it is important to note that there are no established guidelines for how long or intensity red light therapy should be applied, so there is a slight likelihood of adverse effects. More and more brands are launching LED systems for the home so you can treat these skin problems on your own. A high-quality home medical-grade red light therapy device, such as the Joovv, uses LEDs to deliver red and near-infrared light to the body during a treatment session. Make sure your doctor has credentials and an established reputation for performing red light therapy. While the Internet is often full of news about miracle treatments for almost every health condition, red light therapy is certainly not a cure for everything.
Photodynamic therapy (PTD) uses drugs that sensitize the skin to improve the impact of light-based skin treatment for acne. Blue light, green light, and a mixture of different wavelengths have also been the subject of similar experiments on humans. In conclusion, red light therapy is generally considered safe and can be beneficial for people with certain skin conditions or injuries. However, it is important to consult with a doctor before using this type of treatment as there is a slight likelihood of adverse effects.
