Red light therapy (RLT) is a form of treatment that uses low-wavelength red light to stimulate healing of the skin and muscle tissue. It is a combination of light-emitting diodes (LEDs) that emit infrared light and heat. This natural light penetrates deep into the skin, where cells can absorb and use it. The mitochondria, sometimes called “energy generators” of cells, absorb the red light and produce more energy.
This helps cells repair and become healthier, which can lead to a variety of benefits. Many experts believe that red light therapy can help with skin conditions, scarring, and signs of aging, including wrinkles and age spots. A clinical trial published in the journal Photomedicine and Laser Surgery explored light treatment for some basic skin problems in a small group of 136 people. The results showed that red light therapy can reduce inflammation and irritation in the area, while also improving the production of sebum.
It can also help to smooth out fine lines, improve texture and tone, and reduce any redness of the skin. Low-intensity laser therapy (LLLT) does not reduce subcutaneous adipose tissue by local adipocyte injury, but by modulating systemic lipid metabolism. Many studies support red light therapy as an effective treatment modality in the treatment of precancerous lesions such as actinic keratosis. You can easily buy red light devices online, but it's better to get a doctor's opinion on any symptoms before you try to self-medicate. Red light therapy devices for the home are also safe, but they are not as powerful as professional instruments. Make sure your doctor has credentials and an established reputation for performing red light therapy. Many of the human studies involving red light therapy used samples of small sizes, so more research is needed to confirm safety and efficacy.
Other forms of treatment, such as hot or cold lasers, do not have the same advantages as red light therapy from LEDs. When using this type of treatment, a person can see the red light and feel the warmth of near-infrared (NIR) light. Photodynamic therapy can make you more sensitive to light up to three months after the procedure. Red light therapy is a safe and effective way to treat a variety of skin conditions and signs of aging. It is important to consult with a doctor before beginning any type of treatment to ensure safety and efficacy.
