Red light therapy (RLT) is a new and controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, wound healing, and tissue repair, among other conditions. It alters cell function at a cellular level due to a high degree of absorption of red light in the spectral range from 600 to 1300 nm.
Red light is thought to work by producing a biochemical effect in cells that strengthens the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate). By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.
Additional clinical research is needed to prove that RLT is effective. At the moment, however, there’s some evidence to suggest that RLT may have the following benefits:
- promotes wound healing and tissue repair
- improves hair growth
- reduces psoriasis lesions
- reduces pain and inflammation in joints and muscles
- improves skin by diminishing wrinkles, scars & acne
- treats depression
- boosts the immune system
