A method for treating simple wrinkles caused by age or sun exposure comprises treating blood vessels in the wrinkles with laser light. The laser light may have a wavelength between 577 and 585 nm. The laser light may also be a laser light pulse having a pulse duration that is greater than 0.2 msec, or alternatively, greater than 0.5 msec. The output pulse may be generated with a dye laser, for instance, by exciting dye solution in a resonant cavity with one or more flashlamps. A further treatment method comprises irradiating wrinkle-bearing skin with a laser pulse where the pulse duration is selectively matched to the thermal relaxation time of blood vessels in the targeted skin.
