ABSTRACT:
FIELD OF THE INVENTION
This invention relates to human skin care.
More particularly, the present invention relates to a wrinkle removing method and apparatus.
BACKGROUND
Age, sun and many daily activities contribute to wrinkling and damage to skin particularly around the eyes and mouth. Thus, many people apply conditioning compositions in an attempt to eliminate these lines Currently, compositions containing vitamin C are believed to alleviate wrinkles. The vitamin C is carried by a patch which can be adhered to the skin. The problem with this approach is that the vitamin C is mixed into the adhesive on the patch, limiting the amount of vitamin C which can be applied to the area. Furthermore, vitamin C oxidizes in the presence of oxygen. Thus, the treated patches must be sealed in air tight envelopes. Also, the packaging is expensive because the patches have to be stored in foil wrappers to prevent deterioration of the vitamins by ultraviolet light. The envelope for a patch is opened prior to use. This is only partially effective, as the envelopes often contain air which, while small in volume will tend to oxidize the very small amount of vitamin contained on the patch.
Since most of these treatments are used at night during sleep, a strong adhesive must be used to prevent inadvertent removal of the patch. Also, since the vitamin is dried and mixed with the adhesive, to achieve greater amounts of vitamin C strong adhesives must be used. Oil must be used to dissolve the adhesive and remove the patch. This process can be very unpleasant.
Using the known products, the skin must be stretched manually with the fingers of one hand while placing the patch with the other hand. This process is cumbersome and the wrinkles which run parallel to the opposing forces of the fingers are not smoothed as well as wrinkles that run perpendicular to the stretching force. The smoother the wrinkles are when placing the patch the more effective the treatment.
It would be highly advantageous, therefore, to remedy the foregoing and other deficiencies inherent in the prior art.
Accordingly, it is an object of the present invention to provide a new and improved method of treating human skin.
Another object of the present invention is to provide a kit for treating wrinkles.
And another object of the present invention is to provide a method which keeps the composition effective by preventing oxidation and U.V. deterioration.
Still another object of the present invention is to provide a method of permitting the application of greater amounts of the composition.
Yet another object of the present invention is to provide a method and apparatus of treating skin which is easy to apply and remove after treatment.
SUMMARY OF THE INVENTION
Briefly, to achieve the desired objects of the instant invention, in accordance with a preferred embodiment thereof, provided is a method of treating human skin including providing an impermeable patch having an adhesive on a side and a human skin treating composition containing an oxidizable element. A layer of the composition is applied to a portion of human skin and covered with the impermeable patch, whereby oxidation of the layer of the composition is retarded. The skin is smoothed of wrinkles prior to placement of the patch. In a specific embodiment, the composition includes a smoothing ag ent which is allowed to dry prior to placement of the patch. In some embodiments, an adhesive may be employed which gradually deteriorates over a period of time, permitting the patch to be easily removed.
In accordance with a further embodiment of the invention, a skin conditioning kit is provided which includes a composition having an oxidizable element for topical application to wrinkled human skin. The composition is carried within an ultra-violet resistant sealable container for preventing oxidation and damage by ultra-violet light. Also provided is a patch of impermeable material with first and second opposed major surfaces having an adhesive on the first major surface for affixing the patch to the human skin. The adhesive on the first major surface is covered by a removable protective layer.
