Antiphotoaging effects of light-emitting diode irradiation on narrow-band ultraviolet B-exposed cultured human skin cells.


BACKGROUND Antiaging effects of light-emitting diodes (LEDs) have been clinically demonstrated using one or two wavelengths. The mechanism is unclear. OBJECTIVE To examine direct and indirect photobiomodulation effects of LEDs on narrow-band ultraviolet B (NB-UVB)-induced photoaging using seven different wavelengths alone or in combination.
