Method for non-invasive wrinkle removal and skin treatment

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 ...

AI Technical Summary

Benefits of technology

[0013]The handpiece focuses, through a plurality of lenses, the pulsed dye laser light from the pulsed dye laser generator, onto the spot of about 10 mm in diameter, so as to stimulate new collagen growth beneath the epidermis without injuring the surrounding structures.

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 take a month or more to heal under such a procedure.

However they lack the coagulation characteristics and thus allow more bleeding than a carbon dioxide laser during use.

This methodology however, has a low efficiency, and a cryogen coolant must be sprayed on to the skin so as to minimize damaging the top or upper layer thereof and also to minimize pain generation.

This level of energy often causes pain and epidermal damage.
