Abstract
A microabrasion apparatus for providing treatment of skin or other surfaces, is provided herein. A pneumatic source is operatively connected to a recovery container, to a hand tool and a supply container that houses treatment organic particles. The microabrasion apparatus exclusively uses organic particulates to provide natural treatment of skin.
Description
An Apparatus for Variable Microabrasion of Human Tissue and/or Hides.
TECHNICAL FIELD
The present invention relates to an apparatus and method for variable microabrasion using organic particles. This application is a division of published Canadian Patent Application No. 2,416,996.
BACKGROUND ART
Apparatus for making microabrasions, particularly for cosmetic, medical or therapeutic treatment of human tissue e.g., the removal of scars and other skin blemishes are known. In addition, these apparatus may be used to treat hides or other similar types of materials, which require fine abrasion to remove particular attributes.
Typically, these apparatus are used to remove scars and other blemishes by removing surface skin layers by the use of abrasive particles.
The particles are generally driven by a pneumatic source, e.g., a vacuum source.
Such an apparatus includes a vacuum pump connected in series by tubes to a recovery container, a handle and a supply container housing abrasive particles. The handle includes an aperture which, when positioned on a surface to be treated, prevents any external air from entering the tubes and causes the vacuum pump to draw particles from the supply container through the handle and into the recovery container. Whilst passing through the handle, the particles impinge on the surface, causing an abrasive action. The particles are then sucked into the recovery container, where filters ensure that the particles remain in the recovery container.
The flow of particles depends on the flow of air through the apparatus.
Initially, air is drawn into the apparatus through an aperture. When the aperture is positioned against a surface to be treated, then the handle becomes effectively sealed and air is evacuated from the apparatus leading to a reduction in air pressure. As more and more air is evacuated, the particle flow slows down and may eventually stop, requiring the handle to be detached from the surface to allow atmospheric air to flow back into the apparatus. Not only does this lead to loss of treatment time, but also the apparatus can, even when the aperture is just placed on the surface, frequently become blocked. Various systems to overcome these problems have been proposed, e.g., a burst of pressurised air to clear the blockages. These systems are not only more complex but cause the particles to spray outwardly, contaminating the surrounding area. Not only is this a nuisance, but the fine sand-like particles may also constitute a safety hazard.
To overcome this problem, published patent application PCT/AU98/00936, by the present applicant, proposed an apparatus that minimised blockage of the apparatus by using the exhaust port of the vacuum pump to provide a pressurised airflow into the supply container in addition to the suction from the vacuum pump. In that same application, the applicant also proposed an improved hand tool and supply container which substantially overcame these problems.
However, in some applications, it may be desirable to provide an apparatus that not only provides for the controlled fine microabrasion but also one where the abrasion needs to be very intense or strong. This may be required, for example, in medical applications where it may be desirable to remove almost all of the skin layers down to the muscle and fat tissue.
To achieve dermabrasion, the particles must possess a certain level of abrasiveness.
Conunonly used in the industry are aluminium oxide particles whose microscopic shape includes sharp points and edges that provide good abrasion against the skin.
However, for some time, there has been growing concern over the treatment of human bodies with substances that are thought to be associated with various degenerative diseases. Included in this group is the use of aluminium oxide as a dermabrasion particulate. Recently aluminium has been identified as a possible cause of Alzheimer's disease and a number of people have been concerned with its use, however slight.
The use of such abrasive particles can also leave the skin dry and does not provide the exposed skin with any nourishment or a protective layer.
It may therefore be desirable to provide for microabrasion using particles that not only abrade the skin but also treat it at the same time by imparting essential oils, fragrances and other substances.

SUMMARY OF THE INVENTION
It is therefore an object of a first broad aspect of the present invention to provide a microabrasion apparatus that provides a hitherto unknown range of microabrasion intensity and treatment. This object is achieved by providing a microabrasion apparatus that includes one container, where the particles used are organic particles that, when treating the skin, impart essential oils, fragrances or other substances to the skin.

In operation, the hand tool is positioned on a surface to be treated, and the pneumatic source provides for an air flow through the recovery container, the hand tool and the supply container in communication therewith. This thereby draws the organic particles from the supply container through the hand tool and through the aperture in the hand tool, causing the organic particles to impinge on the surface, thereby treating it. The organic particles are finally drawn into the recovery container.
Preferably, according to a first variant, the organic type particles are made from ground up nut shells, e.g., walnut, hazelnut, brazil or almond nut shells, or a mixture thereof.
Preferably, according to a second variant, the organic type particles are made from ground up stone fruit kernels e.g., peach, apricot, nectarine, peacherine, plum or cherry stones, or a mixture thereof.
Preferably, according to a third variant, the pneumatic source is a vacuum pump, which preferably includes a regulator so as to control air pressure within the apparatus.
Preferably, according to a fourth variant, the pneumatic source is a compressor, the compressor being configured variably to control the air pressure fed into the supply container.
Preferably, according to a fifth variant, at least some of the particles are coated with fragrant materials.
Preferably, according to a sixth variant, at least some of said particles are coated with a colourant material.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description of the invention in the parent application and in the present divisional application refers to the accompanying drawings.
Although the description includes exemplary embodiments, other embodiments are possible.
Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.
Turning now to the figures in detail, and specifically Figures 1 and 2, there is shown an apparatus 10 according to the invention in the parent application for making abrasions including a vacuum pump 12 operatively connected in series either to a first assembly including a recovery container 14, a handle 16 and a supply container 18 by tubes 20, or operatively connected to a second assembly including a recovery container 22, a handle 24 and a supply container 26 by tubes 28.
Switch 30 controls a solenoid that switches the vacuum pump from operatively being connected either to the first or second assembly. The vacuum pump is operable by an electric switch and draws air through inlet 34 and exhausts it through outlet 36.
Second assembly supply container 26 is provided with particles that are of a different type, for example bigger (heavier), than those found in supply container 18. If the particles are heavier then they are of a size so that the same density of particles provides a greater abrasive result. Because the particles are substantially heavier and to provide for a more instant particle flow, it is preferable for the second assembly to include a second pneumatic source. Accordingly, a compressor 38 is operatively connected to the supply container 26 or to the container that may house the heavier particles.
In operation, the vacuum pump draws air through either one of the assemblies and the corresponding recovery container and handle. The handle includes an aperture 40, which is positioned against the surface to be treated, and which then causes air and thus particles to be drawn from the corresponding recovery container. The stream of particles then impinges on the surface against which the aperture is positioned causing microabrasions and is subsequently drawn into the recovery container together with any abraded surface debris.
When a low-level of microabrasion is required the switch 30 is operated so that the solenoid operatively connects the vacuum pump in series with the first assembly that in this example houses lighter abrasive particles. In such a configuration the vacuum pump provides suction through the recovery container 14, handle 16 and supply container 18.
The supply container 18 includes an inlet 39 connected to a regulator 42 having an inlet 44 the regulator controlling the amount of air entering the supply container. The air entering the supply container aerates the particles, with the magnitude of air flow providing control over the flux or density of particles drawn though the apparatus. For further details of this operation the reader is referred to the applicants patent specification referred to above.
In use where a different level or type of microabrasion is required, switch 30 operates the solenoid to operatively connect the vacuum pump 12 in series with the second assembly. The supply container 26 of the second assembly as with the first assembly also includes an inlet 40 connected to regulator 42 with an inlet 44. However, unlike the regulator used in the first assembly, the inlet 44 is operatively connected to the compressor 38. Advantageously, when the switch 30 operatively connects the vacuum pump with the second assembly, control switch 46, usually a foot control switch, controls the compressor 38 to provide pressure to the supply container 26. The foot switch may be a variable switch that variably controls the speed and thus the pressure provided by the compressor.
An isolation switch 48 can isolate the operation of (or power to) the compressor from switch 46. Similarly isolation switch 32 controls the first pneumatic source or the vacuum pump.
Thus, if one wants to use the second assembly to provide for microabrasions using heavier particles stored in the recovery container 26 using handle 24 without the extra air flow provided by the compressor, one can turn off switch 48. To assist in the flow of different or heavier particles and provide a greater degree of microabrasion, it is advantageous to use the compressor to provide the greater flow rate and particle density.
The vacuum pump includes a suction regulator 50 that controls the suction provided to the apparatus by the vacuum pump 12. A vacuum gauge 52 advantageously provides an indicator of the vacuum within the apparatus, the vacuum gauge being isolated by the use of valve 54.
Filters 56 ensure that the particle flowing from the supply container, through the handle and into the recovery container do not enter the vacuum pump and cause potential damage. The recovery containers may also include filter 58 that prevents any particles from passing into the vacuum pump.
In use, after the vacuum pump 12 has been activated, the operator chooses whether to use the first assembly or second assembly by operating switch 30. The appropriate hand tool is then used with its aperture 40 positioned against a surface to be treated. Air is then drawn or sucked through the appropriate recovery container, handle and the supply container, the amount of suction regulated by regulator 50.
Regulator 42 that assists in providing aeration of the particles can control the particle flux or density.
When the second assembly is selected by use of switch 30, the foot pump is activated that allows the operator to provide pressurised air to the supply container 26, which can also be controlled by regulator 42. It is however to be understood that the regulators are not essential to the working of the invention and the compressor may simply be turned off and on by the use of the foot switch. However, to provide for fine adjustment of the particle flux or density it is advantageous to have the regulators present.
To allow access to the abrasive particles, the supply and recovery container may include quick-release lids 60 allowing access into the containers. Also to assist in mounting the container to the apparatus, the recovery and the supply container may include projections 62 adapted to engage holding bores 64 on the apparatus.
Timer 66 can assist the operator in keeping a track of time that the machine has been used for. Although not shown, the times could be electrically connected to the pneumatic sources so that the apparatus turns off after a pre-determined amount of time.
Thus one can see that the present dual bottle apparatus provides for a hitherto unknown range of microabrasion properties by providing for different size particles that provide different degrees of microabrasions.
Referring now to Figure 3 there is shown an apparatus according to the invention in the parent application that includes two assemblies, that is, two supply and recovery containers, but only one pneumatic source. In this embodiment, there are two valves 70 and 72 that are adapted to operate in tandem and that control the coupling of the pneumatic source with the relevant supply and recovery containers.
Thus the vacuum pump 12 is either connected so as to provide a pneumatic source to recovery container 14, handle 16 and supply container 18 or alternatively to supply recovery container 22, handle 24 and supply container 26. The vacuum source in the embodiment also includes two regulators 74 and 76 that control exposure to the inlet 78 and outlet 80 of the vacuum pump. A meter 82 may also be present to provide an indication to the operator of the air pressure within the system. The meter can be isolated by valve 82. Filter 56 filters out any particulate matter from entering the vacuum pump.
Whilst at times it may be desirable and even necessary to have independent assemblies, one may also have a joint assembly whereby a plurality of supply containers are in communication with only one recovery container. This is shown in Figure 4 where the supply containers 18 or 26 can be coupled to the one recovery container 14 by the use of valve 30. As was the case in the previous embodiment, one selection of the switch may also turn on a second pneumatic source, e.g., compressor 38.
It has also been discovered, according to the present divisional application, that hard organic material that is sufficiently dried, may be used in micro-dermabrasion apparatus as discussed above, providing an effective abrasive action against the skin whilst at the same time leaving the skin relatively smooth and supple as compared with the use of aluminium oxide particles.
One of the organic materials that have been found to be particularly useful in this aspect of the present invention is ground up nut shells e.g., walnut shells.
These ground up or pulverized shells can be sufficiently dry not to cause blocking in the tubes of a micro-dermabrasion apparatus and yet still have levels of oils and other substances that are left as a residue against the skin on which they are impacted.
In fact, experimentation with different types of organic material has shown, that provided that the particles are sufficiently dry and of a suitable size, a whole range of organic particles may be used. For example, one may equally well use coconut shell, walnut shell, peach kernels and other fruit kernels but to name a few.
Thus a person who wishes to be treated by a certain organic material due to certain properties of that material may choose to have that material prepared in granular form and dried to be used in a micro-dermabrasion apparatus. In this way the skin may be slightly abraded at the same time providing treatment by that organic material to the satisfaction of the consumer.
It is also desirable at times to still use highly abrasive particles such as aluminium oxide. However, it has been discovered that by mixing aluminium oxide particles with organic material that may not be abrasive, one achieves not only good abrasion but also simultaneous treatment of the skin.
Accordingly one can have a choice of different particles to use in a micro-dermabrasion machine including:
(a) purely organic materials according to the present divisional application;
(b) a mixture of abrasive particles e.g., aluminium oxide mixed with organic materials according to the parent application;
(c) abrasive particles that are coated with organic materials, according to the parent application.
This can be achieved according to aspects of the invention in the parent application by having an apparatus with a plurality of supply containers housing different particles. As shown in Figure 5 for example, there may be three different supply containers.
Container 90 may house standard aluminium oxide particles 92, supply container 94 may house organically coated aluminium oxide particles 96 whilst supply container 98 may house organic particles 100. A supply container can be chosen to be in communication with handle 102 and recovery container 104 by the use of valve 106 that controls air flow into the respective supply container and valve 108 that then connects that supply container to the handle 102 and recovery container 104.
In some cases the micro-dermabrasion apparatus may need to be modified to accommodate organic particles. This may include the dimensions of the tubes, airflow as well as the size of the handle and aperture. Further, the supply and collection containers may also need to be modified.
However, it may also be possible to use one apparatus where the supply container is simply changed thereby changing the abrasive particles. Thus, an apparatus such as that shown in Figure 6 may only have one supply container 18 and recovery container 14 and only one pneumatic source 12. To use different particles, the supply container can simply be replaced at the operator's discretion.
Further, instead of having uniform size particles in the one supply container, in some cases one may wish to use a mixture of different sizes. As discussed above, one may choose to have aluminium oxide particles mixed with organic material whose size is smaller than that of the aluminium oxide.
If properly prepared the use of organic particles according to the present divisional application, has been found to provide good abrasive rates. Of course, in some instance, e.g., medical applications it may be preferable to use aluminium oxide particles, or ones coated with an organic material.
The organic particles may not only contain essential oils but they may also contain fragrances that on impact with the skin impart some of those properties. One therefore proposes the use of particles in micro-dermabrasion machines that have been exposed to fragrances. For example, one may very well coat aluminium oxide particles with fragrant materials that impact their fragrance to the skin besides just abrading it.
It is to be understood that one does not need just to coat the abrasive particles; one may provide a mixture of abrasive particles and fragrant particles where the end result is that the abrasive particles abrade the skin whilst the fragrant particles impart the fragrances to the skin.
Of course, it may be that the apparatus contains separate abrasive and fragrant particles and that a user is firstly treated with the highly abrasive particles and subsequently with the organic ones that assist in leaving a residual layer on the skin.
A micro-dermabrasion operator may provide the consumer with a choice of mixing various abrasive particles or particles with various oils/fragrance particles which are then used in the skin treatment. Of course, great care needs to be taken to ensure that the particles do not become too wet, whereupon they will not be able to move freely through the apparatus but will stick to the container and the various tubes.
The impacted skin therefore not only receives the benefits of micro-dermabrasion but also interaction with the abrasive particles, which leaves the skin with residual properties of the substance.
It is to be understood that other additions to the synthetic or organic materials may be used. For example, whilst the above discussion looked at the use of organic abrasive particles or coating particles with such oils and fragrances, one may also add colouring to the abrasive particles whether they are synthetic or organic. This can result in the skin not only being abraded but also leaving a residue of oils/fragrance/colours to the specification of the consumer. The colours may also be natural colours from the organic material or may be colouring added to the particles. Thus it is to be understood that the additive to the abrasive particle are not intended to be limited to those described above.
They may be various, e.g., tea tree oils and essences, colourings, and so on. The only requirement would be that, as a collection of particles, they cannot possess a coating that will provide for adhesion between the different particles.
One can therefore see that the present invention according to the present divisional application teaches the use of organic or organic coated particles together with an apparatus that can accommodate one or more different supply containers that may require one or more recovery containers as well as one or more pneumatic sources. This provides for a hitherto unavailable choice in the treatment of skin both for cosmetic and medical purposes.
For example, one may first wish to be treated with a harsh particle to remove quickly and efficiently top surface skin layers. Subsequently one may wish to use the gentler but still slightly abrasive organic particles that compensate for any serious abrasion whilst imparting to the skin substances that help protect and nourish it.
A further aspect of the present invention provides for the use of an apparatus for microabrasion of human tissue comprising a pneumatic source, a supply container containing organic particles, a hand tool provided with an outlet aperture, a recovery container, and means operatively connected between the pneumatic source, the supply container, the hand tool and the recovery container; for directing an airflow comprising said organic particles onto skin, thereby treating skin.

In use where a different level or type of microabrasion is required, switch 30 operates the solenoid to operatively connect the vacuum pump 12 in series with the second assembly. The supply container 26 of the second assembly as with the first assembly also includes an inlet 40 connected to regulator 42 with an inlet 44. However, unlike the regulator used in the first assembly, the inlet 44 is operatively connected to the compressor 38. Advantageously, when the switch 30 operatively connects the vacuum pump with the second assembly, control switch 46, usually a foot control switch, controls the compressor 38 to provide pressure to the supply container 26. The foot switch may be a variable switch that variably controls the speed and thus the pressure provided by the compressor.
An isolation switch 48 can isolate the operation of (or power to) the compressor from switch 46. Similarly isolation switch 32 controls the first pneumatic source or the vacuum pump.
Thus, if one wants to use the second assembly to provide for microabrasions using heavier particles stored in the recovery container 26 using handle 24 without the extra air flow provided by the compressor, one can turn off switch 48. To assist in the flow of different or heavier particles and provide a greater degree of microabrasion, it is advantageous to use the compressor to provide the greater flow rate and particle density.
The vacuum pump includes a suction regulator 50 that controls the suction provided to the apparatus by the vacuum pump 12. A vacuum gauge 52 advantageously provides an indicator of the vacuum within the apparatus, the vacuum gauge being isolated by the use of valve 54.
Filters 56 ensure that the particle flowing from the supply container, through the handle and into the recovery container do not enter the vacuum pump and cause potential damage. The recovery containers may also include filter 58 that prevents any particles from passing into the vacuum pump.
In use, after the vacuum pump 12 has been activated, the operator chooses whether to use the first assembly or second assembly by operating switch 30. The appropriate hand tool is then used with its aperture 40 positioned against a surface to be treated. Air is then drawn or sucked through the appropriate recovery container, handle and the supply container, the amount of suction regulated by regulator 50.
Regulator 42 that assists in providing aeration of the particles can control the particle flux or density.
When the second assembly is selected by use of switch 30, the foot pump is activated that allows the operator to provide pressurised air to the supply container 26, which can also be controlled by regulator 42. It is however to be understood that the regulators are not essential to the working of the invention and the compressor may simply be turned off and on by the use of the foot switch. However, to provide for fine adjustment of the particle flux or density it is advantageous to have the regulators present.
To allow access to the abrasive particles, the supply and recovery container may include quick-release lids 60 allowing access into the containers. Also to assist in mounting the container to the apparatus, the recovery and the supply container may include projections 62 adapted to engage holding bores 64 on the apparatus.
Timer 66 can assist the operator in keeping a track of time that the machine has been used for. Although not shown, the times could be electrically connected to the pneumatic sources so that the apparatus turns off after a pre-determined amount of time.
Thus one can see that the present dual bottle apparatus provides for a hitherto unknown range of microabrasion properties by providing for different size particles that provide different degrees of microabrasions.
Referring now to Figure 3 there is shown an apparatus according to the invention in the parent application that includes two assemblies, that is, two supply and recovery containers, but only one pneumatic source. In this embodiment, there are two valves 70 and 72 that are adapted to operate in tandem and that control the coupling of the pneumatic source with the relevant supply and recovery containers.
Thus the vacuum pump 12 is either connected so as to provide a pneumatic source to recovery container 14, handle 16 and supply container 18 or alternatively to supply recovery container 22, handle 24 and supply container 26. The vacuum source in the embodiment also includes two regulators 74 and 76 that control exposure to the inlet 78 and outlet 80 of the vacuum pump. A meter 82 may also be present to provide an indication to the operator of the air pressure within the system. The meter can be isolated by valve 82. Filter 56 filters out any particulate matter from entering the vacuum pump.
Whilst at times it may be desirable and even necessary to have independent assemblies, one may also have a joint assembly whereby a plurality of supply containers are in communication with only one recovery container. This is shown in Figure 4 where the supply containers 18 or 26 can be coupled to the one recovery container 14 by the use of valve 30. As was the case in the previous embodiment, one selection of the switch may also turn on a second pneumatic source, e.g., compressor 38.
It has also been discovered, according to the present divisional application, that hard organic material that is sufficiently dried, may be used in micro-dermabrasion apparatus as discussed above, providing an effective abrasive action against the skin whilst at the same time leaving the skin relatively smooth and supple as compared with the use of aluminium oxide particles.
One of the organic materials that have been found to be particularly useful in this aspect of the present invention is ground up nut shells e.g., walnut shells.
These ground up or pulverized shells can be sufficiently dry not to cause blocking in the tubes of a micro-dermabrasion apparatus and yet still have levels of oils and other substances that are left as a residue against the skin on which they are impacted.
In fact, experimentation with different types of organic material has shown, that provided that the particles are sufficiently dry and of a suitable size, a whole range of organic particles may be used. For example, one may equally well use coconut shell, walnut shell, peach kernels and other fruit kernels but to name a few.
Thus a person who wishes to be treated by a certain organic material due to certain properties of that material may choose to have that material prepared in granular form and dried to be used in a micro-dermabrasion apparatus. In this way the skin may be slightly abraded at the same time providing treatment by that organic material to the satisfaction of the consumer.
It is also desirable at times to still use highly abrasive particles such as aluminium oxide. However, it has been discovered that by mixing aluminium oxide particles with organic material that may not be abrasive, one achieves not only good abrasion but also simultaneous treatment of the skin.
Accordingly one can have a choice of different particles to use in a micro-dermabrasion machine including:
(a) purely organic materials according to the present divisional application;
(b) a mixture of abrasive particles e.g., aluminium oxide mixed with organic materials according to the parent application;
(c) abrasive particles that are coated with organic materials, according to the parent application.
This can be achieved according to aspects of the invention in the parent application by having an apparatus with a plurality of supply containers housing different particles. As shown in Figure 5 for example, there may be three different supply containers.
Container 90 may house standard aluminium oxide particles 92, supply container 94 may house organically coated aluminium oxide particles 96 whilst supply container 98 may house organic particles 100. A supply container can be chosen to be in communication with handle 102 and recovery container 104 by the use of valve 106 that controls air flow into the respective supply container and valve 108 that then connects that supply container to the handle 102 and recovery container 104.
In some cases the micro-dermabrasion apparatus may need to be modified to accommodate organic particles. This may include the dimensions of the tubes, airflow as well as the size of the handle and aperture. Further, the supply and collection containers may also need to be modified.
However, it may also be possible to use one apparatus where the supply container is simply changed thereby changing the abrasive particles. Thus, an apparatus such as that shown in Figure 6 may only have one supply container 18 and recovery container 14 and only one pneumatic source 12. To use different particles, the supply container can simply be replaced at the operator's discretion.
Further, instead of having uniform size particles in the one supply container, in some cases one may wish to use a mixture of different sizes. As discussed above, one may choose to have aluminium oxide particles mixed with organic material whose size is smaller than that of the aluminium oxide.
If properly prepared the use of organic particles according to the present divisional application, has been found to provide good abrasive rates. Of course, in some instance, e.g., medical applications it may be preferable to use aluminium oxide particles, or ones coated with an organic material.
The organic particles may not only contain essential oils but they may also contain fragrances that on impact with the skin impart some of those properties. One therefore proposes the use of particles in micro-dermabrasion machines that have been exposed to fragrances. For example, one may very well coat aluminium oxide particles with fragrant materials that impact their fragrance to the skin besides just abrading it.
It is to be understood that one does not need just to coat the abrasive particles; one may provide a mixture of abrasive particles and fragrant particles where the end result is that the abrasive particles abrade the skin whilst the fragrant particles impart the fragrances to the skin.
Of course, it may be that the apparatus contains separate abrasive and fragrant particles and that a user is firstly treated with the highly abrasive particles and subsequently with the organic ones that assist in leaving a residual layer on the skin.
A micro-dermabrasion operator may provide the consumer with a choice of mixing various abrasive particles or particles with various oils/fragrance particles which are then used in the skin treatment. Of course, great care needs to be taken to ensure that the particles do not become too wet, whereupon they will not be able to move freely through the apparatus but will stick to the container and the various tubes.
The impacted skin therefore not only receives the benefits of micro-dermabrasion but also interaction with the abrasive particles, which leaves the skin with residual properties of the substance.
It is to be understood that other additions to the synthetic or organic materials may be used. For example, whilst the above discussion looked at the use of organic abrasive particles or coating particles with such oils and fragrances, one may also add colouring to the abrasive particles whether they are synthetic or organic. This can result in the skin not only being abraded but also leaving a residue of oils/fragrance/colours to the specification of the consumer. The colours may also be natural colours from the organic material or may be colouring added to the particles. Thus it is to be understood that the additive to the abrasive particle are not intended to be limited to those described above.
They may be various, e.g., tea tree oils and essences, colourings, and so on. The only requirement would be that, as a collection of particles, they cannot possess a coating that will provide for adhesion between the different particles.
One can therefore see that the present invention according to the present divisional application teaches the use of organic or organic coated particles together with an apparatus that can accommodate one or more different supply containers that may require one or more recovery containers as well as one or more pneumatic sources. This provides for a hitherto unavailable choice in the treatment of skin both for cosmetic and medical purposes.
For example, one may first wish to be treated with a harsh particle to remove quickly and efficiently top surface skin layers. Subsequently one may wish to use the gentler but still slightly abrasive organic particles that compensate for any serious abrasion whilst imparting to the skin substances that help protect and nourish it.
