Red light therapy is gaining recognition for its potential benefits in treating a variety of skin conditions such as wrinkles, acne, psoriasis, and sun damage, as well as supporting cancer care. This therapy, involving exposure to low-dose red light, can promote healing by stimulating body cells and enhancing blood flow. While studies indicate its effectiveness in reducing pain, inflammation, and tissue damage, particularly in cancer patients undergoing radiation and chemotherapy, some claims regarding its benefits for other conditions remain unverified. The use of red light therapy devices, including powerful laser options and more accessible LED models, is widespread in both clinical and commercial settings, though quality assurance for at-home products is lacking. Experts stress the importance of professional oversight for laser use to avoid potential harm, and ongoing research aims to better understand the full range of therapy applications and its mechanisms.
