Red light therapy (RLT) is a therapeutic technique that uses low-level wavelengths of red light to help treat skin conditions, such as wrinkles, scars, redness, and acne. It is also used to treat muscle tissue and other parts of the body. RLT is also called low-level laser therapy (LLLT), low-power laser therapy (LPLT), and photobiomodulation (PBM) .

RLT works by exposing the skin to a lamp, device, or laser with a red light. A part of the cells called mitochondria, sometimes called the “power generators” of the cells, soak it up and make more energy. Some experts think this helps cells repair themselves and become healthier, which spurs healing in skin and muscle tissue.

Although there is ongoing research and publication of small studies, the full effectiveness of RLT has yet to be determined. However, some studies show that RLT may smooth the skin and help with wrinkles, acne scars, burns, and signs of UV sun damage. RLT may also help with other medical conditions such as psoriasis, stretch marks, and inflammation or edema.

RLT is generally considered safe and uses very low levels of heat. It does not hurt or burn the skin, and it is not the same type of light used in tanning booths, nor does it expose the skin to damaging UV rays. However, many insurance companies do not cover RLT, so it is important to check with your insurance provider to see if it is covered for the condition you might have.

In conclusion, RLT is a therapeutic technique that uses low-level wavelengths of red light to help treat skin conditions, muscle tissue, and other parts of the body. Although there is ongoing research, some studies show that RLT may help with wrinkles, scars, redness, acne, psoriasis, stretch marks, and inflammation or edema. RLT is generally considered safe and does not hurt or burn the skin, nor does it expose the skin to damaging UV rays.
