Method and apparatus for skin treatment

a skin treatment and apparatus technology, applied in the field of system and method for the treatment of skin disorders, can solve the problems of unable severe skin damage or other injury, and the method of Anderson fails to take advantage of the recent developments in light-emitting diode technology, so as to reduce the function of skin barrier, increase the permeability of the skin, and enhance the present invention.

Problems solved by technology

Anderson's method, however, fails to take advantage of the recent developments in light emitting diode technology that permits the use of LEDs for dermatological use in place of much more expensive lasers.
Further, due to the high-intensity nature of lasers, severe skin damage or other injury can occur when the light source is improperly operated.
Further, the laser dyes and other topical compositions described by Anderson are expensive and require FDA approval for their intended use, making the invention expensive and time consuming to implement.
Further, because of Anderson's focus on the oil gland itself, rather than the elimination of the acne bacteria, suitable results may not be achieved in all cases.
Harth et al., as well, failed to appreciate the opportunity for current LED technology to be applied to dermatologic treatment and, like Anderson, do not disclose means for treating sebaceous oil gland disorders without the high cost and time commitment necessary to receive FDA approval require for high-intensity light therapies with topical compositions such as methylene blue.
In each of the known attempts to treat sebaceous gland disorders, extensive investment in expensive light sources and topical drug composition testing is required.
Moreover, none of these attempts addresses the secondary disorder associated with acne—acne scarring.

Acne Reduction—Continous Treatment

[0143] A team of blinded expert graders viewing before and after photos of patients subjected to the non-ablative LILT (“Low Intensity Light Therapy”) of the present invention score the global improvement of visible acne prominent in the facial area.

[0144] Six females are treated to reduce acne by, first, treating their skin with a topical composition containing about 2.5%, by weight copper chlorophyllin as the active ingredient. The treatment includes subjecting the target area of the patient's skin that has been treated with the topical composition to a filtered fluorescent light operated continously and providing full-face coverage, i.e., the entire face of the patient is subjected to the light from the light source. Three treatments over 12 weeks to the entire face with at a light intensity of 11 milliwatts for 15 minutes per treatment session, resulting in a total energy exposure of 10.0 J / cm2. Thermal injury is produced with blood vessels in...

Acne Reduction—Pulsed Treatment

[0145] A team of blinded expert graders viewing before and after photos of patients subjected to the non-ablative LILT (“Low Intensity Light Therapy”) of the present invention score the global improvement of visible acne on the facial area.

[0146] Six females are treated for acne by, first, contacting their skin once nightly for each night during the 2 weeks preceding the treatement session with a topical composition containing a mixture of 2.0% chlorophyll a, 2.0% chlorophyll b, and 5% carotenoids as the active ingredients. The laser diode treatment includes subjecting the target area of the patient's skin that has been treated with the topical composition to a laser diode light having a pulse width of 800 msec and a pulse frequency of 1 hz (1 pulse per second). Three pulses are administered. Six treatments over 12 weeks to the entire face with 400 nm laser diode with a 10 cm beam diameter at an intensity ranging 2500 milliwatts / cm2. The average redu...

Acne and Acne Scarring Reduction Combined Continous Wave / Pulsed Treatment

[0147] Three females showing active acne and acne scarring in the facial area are tested for improvement in scar prominence, skin texture, and scar visibility before and after receiving treatment in accordance with the non-ablative method of the present invention used in conjunction with a topical composition containing the active ingredient chlorophyll in a carrier suspension of microsponges having a diameter of 5 microns or less. Measurements are taken from by utilizing subjective evaluations conducted by trained medical personnel. The topical treatment includes applying the carotenoid composition containing about 5% carotenoids in a liposome carrier (alternatively, microsponges can be used having an average diameter of 5 microns) to the skin of the facial area and allowing it to penetrate the stratum corneum for approximately 15-20 minutes prior to beginning treatment. The first step in the treatment proces...

Abstract

Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the use of multiple light sources for treating skin with or without the use of a topical compositions or photomodulation enhancing agents. Dual light emitting diodes may, for example, be used at relatively low power (less than about 10 J / cm2) to photomodulate skin or living tissue to reduce wrinkles, fine lines, acne, acne bacteria, and other skin disorders.

Description

METHOD AND APPARATUS FOR SKIN TREATMENT [0001] This application is a divisional application of copending U.S. application Ser. No. 11 / 119,378, filed May 2, 2005, which is a divisional of U.S. Pat. No. 6,887,260 filed Aug. 22, 2001, which is a continuation-in-part of U.S. Pat. No. 6,283,956, filed Nov. 30, 1998.FIELD OF INVENTION [0002] The present invention generally relates to a system and method for the treatment of skin disorders and, more specifically, to the treatment of skin using a combination of photothermal, photochemical and / or photomodulatory means. In general, the invention relates to the exposure of the skin to multiple wavelengths of light, alone or in combination with the application of a cosmeceutical composition, naturally occurring chromophore, or other light-activated chromophore to or into the oil gland and surrounding tissue and exposing the composition. BACKGROUND OF THE INVENTION [0003] There are several known techniques for attempting to reduce or eliminate t...
