You may have seen ads or heard friends talking about red light therapy and its many benefits. But is this newfangled treatment safe? We did some digging to find out. Spoiler alert: the short answer is yes, red light therapy is safe! But keep reading to learn more about this exciting treatment and how it works.
How Does Red Light Therapy Work?
Red light therapy (RLT) is a type of phototherapy that uses low-frequency, red and near-infrared light to penetrate the skin. The red and near-infrared wavelengths in RLT are absorbed by the mitochondria in our cells, which leads to an increase in ATP production. This, in turn, promotes wound healing, tissue regeneration, and pain relief. RLT also helps to reduce inflammation and increase collagen production, which can lead to firmer, smoother skin.
Is Red Light Therapy Safe?
Yes, red light therapy is safe! Unlike ultraviolet (UV) radiation—which has been linked to skin cancer—red and near-infrared wavelengths cannot damage DNA. In fact, RLT has even been used to treat cancer patients! One study showed that RLT was able to reduce side effects in cancer patients who were undergoing radiation therapy, such as fatigue and skin irritation.
Side Effects of Red Light Therapy
Although rare, some people may experience minor side effects from RLT, such as:
If you experience any of these side effects, discontinue the use of the RLT device and consult your doctor. Most side effects are mild and temporary.
Red light therapy is a safe and effective way to improve your overall health and appearance! If you’re looking for a way to reduce inflammation, improve skin quality, or get pain relief, RLT may be right for you. Talk to your doctor today to see if RLT is a good option for you.
