Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates generally to skin treatment and therapy, and more particularly, to a device and system for cleansing and improving the health of treated skin through ultrasound, light therapy, and/or cosmeceuticals.

2. Description of Related Art

Skin care is related to enhancing a skin's appearance, cleanliness, and health, and can be accomplished by soap, damage preventative measures, skin-care creams, suntan lotion, moisturizing lotions, powders, makeup, baby products, bath oils, bubble baths, bath salts, butters, and many other types of products. Skin care products are often formulated for different skin types, such as sunscreens to protect the skin from UV radiation and damage, skin lighteners, and treatment products that repair or hide skin imperfections (e.g., acne, wrinkles, dark circles under eyes, etc.), and tanning oils to brown the skin.

Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing (about 20 KHz). The production of ultrasound is used in many different fields, typically to penetrate a medium and measure the reflection signature or supply focused energy. The reflection signature can reveal details about the inner structure of the medium. Ultrasound is used in many applications, though the most well-known application is to produce pictures of fetuses in the human womb.

Light therapy consists of exposure to daylight or to specific wavelengths of light using lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light, usually controlled with various devices. The light is administered for a prescribed amount of time and, in some cases, at a specific time of day. Light therapy has been used in treatment of the skin such as acne, in treatment of sleep disorders by putting light in the retina, and in treatment of some psychiatric disorders such as seasonal affective disorder (i.e., winter depression).

U.S. Pat. No. 7,066,941 describes an apparatus for skin treatment, where aging or damaged skin is treated by irradiating affected skin areas with an effective amount of visible light emanating from an optical apparatus having a wavelength of about 400 nm to about 500 nm. Green light (about 500 to about 590 nm) may be used as adjunct therapy with blue/violet light in some embodiments.

U.S. Pat. No. 5,843,072 describes a method and device for treatment of unwanted veins by a combined sclerotherapy and light treatment. Near infra-red wavelength light is preferably used in the light therapy due to its better depths of penetration through the skin to deeper lying, larger vessels such as varicose veins.

U.S. Pat. No. 5,259,380 describes a light therapy system. With a designated wave length in the infrared bandwidth and 5-10 minute treatment regimens of continuous and pulsed operations has been effective in alleviating various musculoskeletal disorders, skin ulcers, and delayed post-operative wound healing.

Conventional methods fall short on providing an ultrasonic and light therapy method to exfoliate. cleanse, and smooth skin.
