What does Mayo Clinic say about red light therapy?

Mayo Clinic describes red light therapy as a treatment that uses low-wavelength red light to address skin conditions such as wrinkles, scars, and persistent wounds, noting that early research shows promise but that evidence remains limited and largely preliminary.

Mayo Clinic's position is that red light therapy appears safe when used as directed, with few known side effects, but that large-scale clinical trials are still needed to confirm effectiveness for most claims. The organization notes that red light therapy is distinct from UV light and does not carry the same skin-damage risks. Mayo Clinic advises consulting a dermatologist before starting red light therapy, particularly for anyone with photosensitive conditions or who takes medications that increase light sensitivity.
