Red light therapy (RLT) is a powerful therapeutic technique and an alternative healing method. It uses red low-level wavelengths of light for a variety of therapeutic purposes, including wound healing, scars, and other skin issues, inflammation, pain, hair growth, and sleep quality.
Red light therapy was originally used in the 1990s by scientists to help grow plants in space, because of its ability to promote photosynthesis and plant growth. Further research and experience have found that alterations influence cellular redox state and function and positively affect their photosensitivity resulting in a variety of health benefits.
Today it is widely for the listed therapeutic benefits. It is used in medical settings for skin conditions, wounds, and chemotherapy side effects, in salons for cosmetic skin concerns, and even in personal home settings for any desired benefits.
