Abstract

ABSTRACT

The invention relates to process of, and appa-ratus for treatment of human skin to reduce blemishes such as depressed scars, wrinkles, stria and similar skin irregularities which may be caused by aging. The process comprises applying a series of electrical impulses of low voltage and intensity to the skin to sequentially stimulate the endoblastic, mesoblastic and ectoblastic functions of the skin, and then to act on the dysmetabolic disorders of the skin. The frequency of each impulse is a harmonic of the preceding impulse and each impulse is applied for a predetermined and approximately equal length of time. The impulses are less than 0.25mA and less than 15 Volts.

Description

This invention relates to a process and appear-tusk fur treatment of human skin.

The human skin can be afflicted by blemishes such as wrinkles, strip, depressed scars and other similar irregularities which may be caused by aging.

Various proposals have been made in order to reduce or remove the aforesaid irregularities. For example, cosmetic creams have been proposed for the treatment of wrinkles, and whilst such creams prove useful in the hydration and nutrition of the skin, they do not have any specific action on wrinkles and similar irregularities.
Alternatively, the wrinkles, strip, depressed scars and other similar irregularities can be removed by surgery such as "lifting", or in the case of wrinkles by the injection of a suitable compound, such as silicone or collagen under the skin. Other treatments include the massage or grinding of the skin.

However, surgical treatment can be expensive, and sometimes painful especially where the surgical treatment requires removal of parts of the skin to rev dupe wrinkling. Although some of these treatments are effective in masking the blemishes, none of them actual-lye improve the physiology of the dermis and epidermis Furthermore, none of these treatments specifically treat only the blemishes themselves.

It is an object of the present invention to provide a process and apparatus for reducing skin aye blemishes such as wrinkles, depressed stars and other similar irregularities which do not require the spin to be treated surgically, or by cosmetic substances.

It is a further object of the invention to provide a process and apparatus which does not require invasion of the human body below the inner surface of the skin, and which can be used by individuals without specialized training in the use of the process and apparatus.

It has been discovered that the passage of a low intensity (less than 0.25 ma direct current interrupted by rest periods of approximately 1 msec each, at a low frequency less than 200 hertz) for short periods of time (less than 2 minutes) in the skin of humans has beneficial effects on the cellular metabolism of the skin. More particularly, it has been discovered that certain frequencies have more effect on particular tissues comprising the skin. For example, a frequency of approximately 5 hertz acts more specifically of the endoblastic structures and the tropic function of the skin, a frequency of about 10 hertz acts on the mesoblastic function, a frequency of about 40 hertz on the ectoblastic function while a frequency of 80 hertz has more effete on aysmetabolic troubles. After a few sessions, wrinkles tend to "fill up" as the result of a better physiology of the subcutaneous tissues.

In order that the above objects will become apparent, and so that the invention can be understood and carried into effect, apparatus for effecting the process of the invention will now be described with reference to the accompanying drawings, in which Figure l is a block diagram of one form of Papa-fetus in accordance with the invention;
and Figure 2 is a diagrammatic view of an alterna-live apparatus for carrying out the process of the invention.

Referring to Figure l of the drawings 10 India gates a positive electrode and 12 a negative electrode, each of which comprises a needle which resembles an acupuncture n edge and is capable of being inserted in the skin of a human being.

lye positive electrode lo is connected to the positive terminal of a direct current generator (butte-rye transformer-r~ctifier, etc.) 14 by means of a con-ductile element 16, and connected in flow series between the generator 14 and the electrode 10 are an on-off switch 18, a resistance 20 and a potentiometer 22.
The negative electrode 12 is connected to the negative terminal of the generator 14 by means of a con-ductile element 24, which includes a contact breaker 26.
A frequency modulator pa enclosed in box 44 is connected between element 16 and 24 to activate the contact breaker 26.

.~, The frequency modulator is constructed in a man-nor well Known to those skilled in the art to provide direct current pulses separated by zero current periods of approximately 1 msec each at four predetermined ire-quenches for the electrical current passing there-through, namely frequencies of approximately 5, 10, 40 and 80 Ho in that order when the system is activated.
In addition, the frequency modulator 28 also includes means whereby the duration of each frequency is prude-termined, in this particular example, the duration is thirty seconds. Such means are well known to those skilled in the art.

In addition, the frequency modulator 28 is opened by an on-off button 30 also enclosed in box 44.

In order to provide an indication that elect tribal current is being supplied to the circuit an elect tribally conductive element 32 is connected between the elements 16 and 24, downstream of the switch 18, which element 32 includes a resistance 34 and a lamp 36, which in this example glows red when electrical current flows through the element 32 upon closing of the switch 18.

A further conductive element 38 is connected between the elements 16 and 24 downstream of the element 32, and like the element 32 includes a resistance 40 and lamp 42. Thus when the on-off button 30 is activated to close the circuit after closing of the switch 18, the lamp 42 will be connected to the negative terminal of I`

the battery 14 via the modulator 28 and thus illuminate Ed When the above described apparatus is to be used to treat wrinkles for example, the needles are slightly inserted (2 or 3 mm) into the skin at each end of the wrinkle to be treated.

Although needles are used in this example, -they could be replaced by electrodes applied onto the skin at each end of the wrinkle to be treated after an appropriate electrolytic gel or solution has been coated onto the skin.

The electrical circuit is then activated by closing the switch 18 and the frequency modulator switch 30 is moved to the closed position.

Thus current will flow through the circuit, at four successive predetermined frequencies and for a predetermined time as previously described, and each frequency produces a particular reaction in the cellular metabolism of the skin.

The initial frequency of Ho stimulates the endoblastic structure and tropic function of the skin, whilst a frequency of 10 I stimulates the mesoblastic function.

The subsequent application of I Ho activates an ectoblastic function and finally the application of the 80 Ho frequency acts on dysmetabolic disorders. Each frequency is applied for thirty seconds, and after the 80 Ho frequency, the frequency modulator automatically switches off at which point the lamp I is no longer illuminated, thus indicating that the electrodes are disconnected from the battery 14.

The above described process can be repeated, for example, at weekly intervals.

Whilst the electrical current is flowing through the electrodes, the person using the apparatus may expel wryness a tingling or prickly sensation, but this can be reduced to an acceptable level by adjustment of the potentiometer.
Although in this example, the system has been designed in order that the maximum current be inferior to 0.25 ma any other current which does not endanger the health of the user may be used.
Figure 2 of the drawings illustrate apparatus in accordance with the invention which includes two pairs of electrodes each pair comprising a positive electrode So and a negative electrode 52. Each pair of electrodes is included in an electrical circuit, not shown which can be connected to a domestic electrical supply by means of an electrical lead 54.

The electrical circuit includes a potentiometer 56 for each pair of electrodes, and a frequency regular ion, whereby the 110 volts 60 Ho of a domestic supply can be varied so as to produce a 9 to 15 volt direct current output at the input of the modulator 28 electrodes together with a current cycle as described with reference to Figure 1 of the drawings.

In addition, the apparatus also includes an on-off button 58.

Thus the apparatus described with reference to Figure 2 of the drawings can be used in the manner described with reference o Figure 1 of the drawings, and in addition, the overall size of the apparatus is such as to render it portable.

While in the above description, frequencies of 5, 10, 40 and 80 hertz are specified, it should be understood that these are approximate frequencies and that the precise frequencies which provide the optimum results vary from one individual to another.

The optimum frequencies for a particular indivi-dual may be measured by constantly measuring the pulse rate of the individual while gradually increasing the frequency of the current applied to an area of the spin of the individual as described above. Each time the pulse rate diminishes slightly, the frequency will correspond to an optimal frequency.

Tests carried out on a number of individuals have revealed that the average optimum frequencies of the group included 4.56, 9.125, 36.54 and 73 hertz respectively.

Thus, the effectiveness of apparatus in which the frequencies have been preset will vary according to the extent of deviation of the preset frequencies from the optimum frequencies applicable to the individual using the apparatus.

although the use of the method and of the apparatus was described to be for use in relation to wrinkles, it should be understood that this method and the apparatus are useful for the treatment of any type of blemishes which are caricatured by a certain reduction in the physiologic activity.

It will be seen therefore that the above desk cried process enables selected areas of the skin to be treated without the necessity of surgery, cosmetics or the injection of silicone or similar substances.

In addition, the apparatus does not require the services of a skilled operator, and therefore, the Papa-fetus can be used in the home.
