Abstract
Abstract A method for the treatment of wrinkles on human skin, by stimulating collagen growth beneath the epidermis layer, comprising the steps of: arranging a pulsed dye laser generator in light communication with a pulsed dye laser delivery device. The pulsed dye laser delivery device is applied against tissue having wrinkles. The pulsed dye laser generator generates a pulsed dye laser light. A pulsed dye laser light from the pulsed dye laser delivery device is directed onto the tissue, to reach hemoglobin in a collagen layer up to about 1.2 mm. beneath the surface of the tissue to effect growth changes therein.

154 words
A method for the treatment of wrinkles on human skin, by stimulating collagen growth beneath the epidermis layer, comprising the steps of: arranging a pulsed dye laser generator in light communication with a pulsed dye laser delivery device; applying said pulsed dye laser delivery device against tissue having wrinkles; generating a pulsed dye laser light by said pulsed dye laser; and directing said pulsed dye laser light from said pulsed dye laser delivery device onto said tissue, to reach hemoglobin in a collagen layer beneath the surface of said tissue; adjusting said range of pulsed dye laser light generated to a wavelength of about 585 nanometers; generating said pulsed dye laser at a pulse width of about 450 microseconds; directing said pulsed dye laser light at the tissue at a target spot diameter of about 10-mm; and maintaining a fluence of said pulsed dye laser light of less than 5 Joules per square cm.
