Red light therapy works best for skin when used 2-3 times weekly for about 10-15 minutes per session. For pain or swelling issues, you might need longer sessions (15-20 minutes) more often (3-5 times weekly). Always give your skin a day off between treatments so it can properly recover.

Near-infrared light (700-1400 nm wavelengths) tackles inflammation better than other types since it reaches deeper tissues and helps calm immune responses. Far-infrared can work for deep joint problems, but near-infrared remains the go-to choice for most inflammation issues.
