Method for non-invasive wrinkle removal and skin treatment
View Patent ↗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.
