Problems solved by technology

The use of chemical peels has fallen out of favor, because it is difficult to accurately control and predict the depth of tissue injury after such peels are applied.
Deeper chemical peels in particle have an increased risk of hypopigmentation and scarring.
This method is not well controlled, and is very difficult especially around the eyelids.
While carbon dioxide lasers may remove about 150 microns of skin, that skin may t

Embodiment Construction

[0021]Referring now to the drawings in detail, and particularly to FIG. 1, there is shown the present invention, which comprises a system 10, and methodology for nonivasive wrinkle removal for the modification of collagen beneath the epidermis. The laser system 10 of the present invention, in a preferred embodiment, utilizes a pulsed dye laser 12 having a deep tissue-penetrating wavelength of about 585 nanometers (nm) laser, so as to target hemoglobin “H” of blood in the skin tissue “T”. The preferred pulsed dye laser 12 generates a particular laser wavelength energy of 585 nanometers, which is absorbed by the hemoglobin “H”. The heat is generated in the skin tissue “T” area up to about 1 mm in depth and typically uses energy of less than 5 Joules per square cm, having a preferred target spot size “S” of about 10 mm diameter circle or larger.

[0022]The pulsed dye laser apparatus 12 of the present invention includes a handpiece 14 connected by an optical fiber or wave guide 16, critic...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of The Invention[0002]The present invention relates to the field of resurfacing skin, or wrinkle removal using laser radiation for treatment of underlying layers of skin.[0003]2. Prior Art[0004]Plastic surgeons, dermatologists and their patients continually search for new and approved methods for treating the effects of an aging skin. Historically, the treatment of facial wrinkles was primarily accomplished with the use of chemical peels or dermabrasion. The use of chemical peels has fallen out of favor, because it is difficult to accurately control and predict the depth of tissue injury after such peels are applied. Deeper chemical peels in particle have an increased risk of hypopigmentation and scarring. Such injury to the top layer of skin, which would be peeled away, would permit new cells to supposedly rejuvenate the skin. A less expensive way of injuring the outer layer of the skin is the utilization of an abrasive wheel, to rough off ...
