Abstract
A method of treating mammalian skin tissues for causing a predetermined physiological change in the mammalian skin tissues. A treatment composition of matter is applied onto the mammalian skin. The mammalian skin is irradiated with a first pulse having a power density above an activation threshold power density and with a second pulse. The first pulse is emitted for a duration of from about 1 femtosecond to about 1 hour, and the first pulse is separated from the second pulse by an inter-pulse interval of from about 1 microsecond to about 10 seconds. The treatment composition of matter includes a photoreactive substance and is applied in an amount sufficient to cause physiological changes within the mammalian skin tissue upon the mammalian skin tissue being irradiated.
