Red Light Therapy Safety: FDA-Cleared, Health Canada Class II
Quick answer: is red light therapy safe?
Red light therapy has an excellent safety profile backed by decades of research and clinical use. Many devices have received regulatory clearance from the FDA and Health Canada for safety. Known side effects are mild: temporary skin flushing, occasional eye strain from bright light, rare headaches during long sessions, and rare mild skin sensitivity. The primary safety variable is device quality - cheap panels may emit EMF at unsafe levels, use incorrect wavelengths, or deliver inconsistent power output. Red light follows a biphasic dose response: too little does nothing; the optimal range delivers benefits; too much may reduce effectiveness.
