INVENTION TITLE: "ADHESIVE MAGNESIUM PATCHES" DETAILS OF ASSOCIATED PROVISIONAL APPLICATION NO'S: Australian Provisional Patent Application Number 2012901010 filed on 14 March 2012 The following Statement is a full description of this invention including the best method of performing it known to me/us: TITLE "ADHESIVE MAGNESIUM PATCHES" FIELD OF THE INVENTION [00011 The present invention relates to an adhesive magnesium patch. BACKGROUND OF THE INVENTION [00021 For many years, magnesium has been known for its ability to relax muscles. There are a huge number of studies that show magnesium contains skin healing and skin repair properties. In addition, studies have shown magnesium to be effective in reducing muscular cramps due to its muscle relaxant capabilities. Due to its muscle relaxing capabilities, magnesium offers the ability to help relax aching muscles throughout the body, including muscles of face where cosmetically unappealing lines and wrinkles form. [0003] Magnesium has been shown to work systemically and topically. Being effective topically therefore enables a magnesium treatment to be applied only where needed. A treatment need not rely on the nuisance of ingesting a pill and absorbing the active ingredient systemically where it is not needed throughout the body. [0004] Topically, this element is commonly used in a water soluble base. Magnesium can commonly be purchased in a salt form that is easily dissolved in a bath to allow absorption through the skin. It has been therapeutically used in a bath to not only reduce muscular tension and produce a relaxant effect but also to reduce inflammation that may be present in and/or on the skin, for example, from skin irritation and blemishes. [0005] However, the making of a full body bath or merely a face bath for that matter is not only time consuming but very inefficient. This is especially evident when only very small specific areas of the body are requiring magnesium therapy, such as skin blemishes, lines and wrinkles on the face and small areas of tense muscles. In addition, placing the whole face into a warm bowl of water (face bath) with magnesium salt may be very 2 inconvenient, messy and time consuming. The person being treated would need to remain with his or her head under water for a significant amount of time, constantly holding their breath or using a snorkel device to get a good amount of magnesium uptake through the skin. Furthermore, the eyes would need to be kept tightly shut or the wearing of goggles would be necessary to avoid them being irritated. [0006] Furthermore, if the area benefiting from magnesium therapy is small, the inefficiency of immersing the whole body or a majority of it into a bath of magnesium is not only an unnecessary or over use of a medicinal product, but also a waste of water. Hence money and also time are wasted. [0007] Another current topical use of magnesium is as an oil alone. Unfortunately, oils can be off-putting when applied to the skin due to the oily feel and sheen that is left. [0008] In addition, another issue that arises with available magnesium applications, such as magnesium in liquid, cream, gel or lotion form is that the ingredients are exposed to their surroundings. This means that the ingredients are able to be affected by a non sterile and uncontrolled environment, which can cause their quality and/or quantity to be degraded by temperature, weather and other factors. Also, the exposed application can be easily sweated out from the skin, or simply just rubbed off. [0009] The present invention attempts to overcome at least in part the aforementioned disadvantages of previous magnesium therapies. SUMMARY OF THE INVENTION [0010] In accordance with one aspect of the present invention there is provided an adhesive patch containing magnesium in a water soluble salt form. [0011] Preferably, the patch comprises a lower adhesive surface and an upper surface which is visible when the patch is worn. 3 [0012] In accordance with another aspect of the present invention, the patch may optionally comprise additional ingredients which aid the targeted therapy. [0013] In accordance with a further aspect of the present invention there is provided a method for applying magnesium to a patient's skin comprising: a) impregnating an adhesive patch with magnesium in a water soluble salt form; and b) adhering said patch to a patient's skin. [0014] The patch may act as an occlusive dressing to help enhance magnesium penetration compared with existing magnesium therapies. In addition the patch may provide a more controlled and sterile environment optimal for skin therapy. The patch may also offer a more convenient solution than existing therapies such as a magnesium bath. The adhesive quality of the patch may allow magnesium treatment overnight. The patch provides benefits including specific magnesium therapy to target areas, a saving of time, removal of the requirement to be isolated to a bath and lowering the instance of absorption of more magnesium than therapeutically needed. BRIEF DESCRIPTION OF THE DRAWINGS [0015] The present invention will now be described, by way of example, with reference to the accompanying drawing, in which: Figure 1 is a schematic view of an adhesive magnesium patch in accordance with one aspect of the present invention. DESCRIPTION OF THE EMBODIMENTS [0016] Referring to Figure 1, there is shown an adhesive magnesium patch 10 in accordance with one aspect of the present invention. In this particular embodiment, the patch 10 comprises a lower surface 12 intended for contact with a patient's skin. [0017] Said lower surface 12 comprises an adhesive property which allows for the patch 10 to be attached to a patient's skin. This lower surface 12 may optionally further 4 comprise magnesium in a form able to be absorbed into skin, for example, magnesium salt. This lower surface 12 may optionally further comprise other ingredients to aid desired therapies or be arranged so as to receive other ingredients applied to it. [0018] The patch 10 may further comprise an upper surface 14. Said upper surface 14 is visible when the patch 10 is adhered to skin. Said patch 10 may act as an occlusive barrier and the level of occlusion provided may be achieved through the selection of material used for upper surface 14. The selection of material used for upper surface 14 may also provide the desired thickness, according to the area to be treated, of the patch 10. In a preferred embodiment of the present invention, a relatively thin material may be used for upper surface 14 to provide a thin patch 10 for use on facial skin. The patch 10 may be constructed from a variety of suitable materials including but not limited to paper, plastic, silicon and/or foam. [0019] The overall shape of the patch 10 may depend on the size of treatment area and the type of therapy desired. In accordance with one aspect of the present invention, the patch 10 may be relatively small and the shape may somewhat represent a "C" when the patch 10 is intended for use on lines on the corner of the mouth. On the other hand, in accordance with another aspect of the present invention, the patch 10 may be considerably larger and of a more regular shape when intended for use in treating muscle aches, such as abdominal cramps. [0020] In accordance with another aspect of the present invention, there is provided a method for applying magnesium to a patient's skin comprising impregnating an adhesive patch with magnesium in a water soluble salt form and adhering said patch to a patient's skin. Preferably, the lower surface 12 of the patch 10 may be arranged so as to receive magnesium applied to it. The magnesium and optional other ingredients may be provided in numerous confirgurations including but not limited to a solution or a powder. Preferably, said powder may be prepared for mixing with water immediately prior to application onto the patch 10 to create an aqueous solution. In accordance with this aspect, preferably the patch 10 may be provided within a kit comprising water activated 5 adhesive patches; an aqueous solution comprising magnesium or water and magnesium salt in a powder suitable for creating an aqueous solution; and optionally other ingredients. Provision of the patch 10 within a kit allows the same resultant therapeutic outcome as a patch 10 comprising magnesium salt within the lower surface 12. Additionally, there is the added advantage of enabling a larger variety of ingredients to be used such as those that have a short shelf life. [0021] In use, the adhesive lower surface 12 of the patch 10 may be adhered to the skin of a patient. The adhesion of the lower surface 12 may be activated by contact with water. The water may be provided as moisture from the patient's skin. [0022] Said lower surface 12 may comprise magnesium salt able to be absorbed into the skin. The magnesium is carried on a base, in the form of a salt compound. This compound may be dissolved and dissociated upon the addition of water, which may be in the form of moisture from the patient's skin, to release magnesium freely to the surface of the skin. In accordance with one aspect of the present invention, the salt compound may be magnesium chloride. In accordance with another aspect other compounds including but not limited to magnesium sulphate may also be used to achieve a similar result with the addition of water. [0023] Therefore, in this way, the water provides not only adherence of the patch 10 to the targeted skin, but also activation of the release of magnesium to the skin. In accordance with one aspect of the present invention, the lower surface 12 may also incorporate additional ingredients that aid in the targeted therapy of the patch 10. These additional ingredients may include but not be limited to vitamin E, for wrinkle/line reduction, and/or for zinc, for blemish repair. Said additional ingredients incorporated in lower surface 12 may include but not be limited to those with skin repair, skin rejuvenation and muscle relaxant properties. [0024] In accordance with another aspect of the present invention, the lower surface 12 of the patch 10 may be arranged so as to receive magnesium salt and optionally other 6 ingredients applied to it. In accordance with this method for applying magnesium salt to a patient's skin, said magnesium salt and optional other ingredients may be mixed with water to form one or more solutions which may be applied to the patch 10. The application of said solutions may utilise various methods including but not limited to spraying or pouring onto the patch 10, prior to application of the patch 10 to the skin. [0025] The level of occlusion provided by the patch 10 may depend on the treatment area to be targeted as well as the type of therapy desired. In accordance with one aspect of the present invention, a highly occlusive patch 10 may allow greater penetration of ingredient(s) into the skin. A highly occlusive patch 10 may also provide skin moisture retention, useful for skin repair and minimising the appearance of skin ageing as well as being preferable for skin healing. However, in accordance with another aspect of the present invention, where treatment of muscle cramping is the desired therapy, a less occlusive patch 10 may provide acceptable magnesium penetration but less moisture retention, being more desirable for this therapy. [0026] After use, the patch 10 may be removed by simply peeling off. For more stubborn adhesive or for removal from sensitive or hair-covered areas of skin the patch 10 may be removed through rubbing the patch 10 with oil, for example olive or vegetable oil. Hence the patch 10 may be removed easily and painlessly. [0027] Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention. 7
