Description

TITLETRANSDERMAL SKINCARE DELIVERY, HAIR AND SKIN REJUVENATION DEVICETECHNICAL FIELD

[0001] The invention is directed to a skin care device configured to provide a plurality of skin treatments to the skin of a user.BACKGROUND

[0002] The skin care industry is saturated with a plethora of products and treatments promising improvements in skin health and appearance. These range from creams and lotions to advanced skin care devices. Despite the extensive array of options, many consumers experience unsatisfactory results, often due to the generic nature of product instructions and variability in individual skin responses. As such, many users either fail to achieve their desired outcomes or become discouraged and seek alternatives. This issue is compounded by the fact that even consultations with dermatologists, while beneficial, may not always provide a sustainable or cost-effective solution. As a result, there is a growing need for more personalized and scientifically validated methods to enhance skin care efficacy.

[0003] Recent advancements in dermal care technology have introduced several sophisticated techniques that aim to improve skin health and appearance more effectively than traditional products. These methods include electroporation, ultraviolet (UV) light therapy, lightemitting diode (LED) treatments, vibration therapy, and transdermal delivery systems. Each of these approaches offers distinct advantages and can be tailored to address specific skin concerns more precisely.

[0004] Electroporation is a technique that involves the application of electrical pulses to the skin, creating temporary pores in the cell membranes. This process facilitates the penetration of active ingredients from topical products into the deeper layers of the skin. Electroporation enhances the efficacy of dermal treatments by increasing the absorption of these ingredients, which can result in improved outcomes for various skin conditions such as wrinkles, hyperpigmentation, and dehydration. By using electrical impulses to transiently disrupt the skin barrier, electroporation enables more effective delivery of therapeutic agents and maximizes their potential benefits.

[0005] Ultraviolet light therapy involves the use of UV light to treat various skin conditions and promote skin health. UV therapy can be divided into UVA, UVB, and UVC light, each of which interacts with the skin in different ways. For example, UVB light is often used for treating conditions like psoriasis and eczema, while UVA light is commonly employed in phototherapy to address skin aging and pigmentation issues. Controlled exposure to UV light can stimulate collagen production, enhance skin tone, and improve overall skin texture. However, it is essential to use UV therapy with caution to avoid potential adverse effects such as skin damage and increased risk of skin cancer.

[0006] LED treatments use specific wavelengths of light to target various skin concerns. Different colors of LED light, such as red, blue, and near-infrared, offer distinct therapeutic benefits. Red LED light is known for its ability to stimulate collagen production and reduce inflammation, making it effective for anti-aging and skin rejuvenation. Blue LED light targets acne-causing bacteria and is used for acne treatment. Near-infrared LED light penetrates deeper into the skin, promoting wound healing and improving skin elasticity. LED treatments are non- invasive and can be incorporated into a regular skin care routine to address multiple skin issues simultaneously.

[0007] Vibration therapy involves the use of mechanical vibrations to stimulate the skin and underlying tissues. This technique can enhance blood circulation, increase lymphatic drainage, and promote collagen production. Vibration therapy is often integrated into facial massagers and other skin care devices to provide additional benefits such as improved skin tone and reduced appearance of fine lines and wrinkles. By applying gentle vibrations to the skin, this method helps to increase product absorption and enhance the overall effectiveness of dermal treatments.

[0008] Transdermal delivery systems are designed to deliver active ingredients through the skin barrier directly into the bloodstream. These systems utilize various technologies, such as microneedling, iontophoresis, and ultrasound, to enhance the penetration of therapeutic agents. Microneedling creates micro-injuries in the skin, which stimulates collagen production and improves the absorption of topical treatments. Iontophoresis uses electrical currents to drive active ingredients into the skin, while ultrasound employs sound waves to enhance ingredient penetration. These methods provide targeted delivery of skin care products, allowing for more effective treatment of specific skin concerns.

[0009] While these advanced techniques offer promising solutions for improving skin care outcomes, it is important to consider several factors. Firstly, individual skin types and conditions vary, and what works for one person may not work for another. Personalized assessments and treatments are crucial to achieving optimal results.

[0010] Moreover, the integration of these advanced techniques into a comprehensive skin care regimen should be approached with caution. Financial or time constraints mean that many people are unable to access treatment.

[0011] This invention was conceived with these shortcomings in mind.

[0038] Embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments, although not the only possible embodiments, of the invention are shown. The invention may be embodied in many different forms and should not be construed as being limited to the embodiments described below.DETAILED DESCRIPTION

[0039] The present invention relates in general to a method and device for adaptive skin care. The disclosed method and device are configured to detect a user’s skin quality using one or more sensors. Skin quality measurements are used for providing treatment or therapy recommendations. Overtime, the recommendations may be adjusted by tracking how the user’s skin quality has changed in relation to the applied therapies or treatments. An algorithm of theapplication on the user device is configured to converge upon an optimal skin care solution for a user.

[0040] Fig. 1 is a diagram of the internal mechanisms of a skin care device 100 according to an aspect of the present invention. The skin care device comprises a cavity within the head adapted to receive a cartridge (shown in light shade / white). The cartridge contains a reservoir (shown in light shade / white) having a plunger 140 for expelling the liquid when engaged by a driving or push mechanism. In this particular embodiment, there is provided a drive mechanism 150 disposed at the proximal end of the body, a drive shaft 160 in cooperation with the drive mechanism, a piston 170 adapted to engage with the plunger 140 to expel the liquid from the reservoir through a fluid pathway 180 to a skin contacting surface 190 of the head. In some embodiments, the piston 170 is threaded, and the driving mechanism is effectuated by a compound lead screw and at least one keyway.

[0041] Fig. 2 is a diagram of the cartridge 130 engaging the skin contacting surface of the head 190 (here shown removed). The cartridge 130 is releasably engageable with the fluid pathway 180 of the skin contacting head 190. Once connected, the skin contacting surface of the head 190 is connected to the skin care device 100 allowing the cartridge to 130 to fill the cavity 120 of the skin care device 100. Once connected, this forms the head 110 of the skin care device 100. The cartridge 130 may engage the skin contacting surface of the head 190 through an interference fit, screw fit, snap fit etc.

[0042] It may be advantageous to have the cartridge engageable to a skin contacting surface of the head, such that the cartridge is housed within the cavity for user friendliness. In some skin care devices, the cartridge is housed in the proximal end of the device, meaning the user must hold the distal end of the device to try and unscrew or unclip the proximal end of the device to replace the exhausted or expelled cartridge. This causes user issues, including, but not limited to bacteria from the hands contacting the skin contacting distal end of the device, potential residual oils from skin care liquids or sebum from the face causing the device to become slippery, and general ergonomic disadvantages. By housing the cartridge in the proximal end of the device, and having the cavity accessible by removing a skin contacting surface of the head, the user is able to hold the device in the same manner that they would when in use, making the cartridge changing process much simpler, easier, and more ergonomic.

[0043] This may also allow the user to visually inspect the level of liquid in the cartridge visually, whereas most other skin care devices require you to insert the cartridge up into the proximal end of the device causing numerous issues in terms of usability.

[0044] When the cartridge is changed, the piston will need to retract so that the skin contacting head can be released from the body. In some embodiment the piston is retractable by a selectable button on the interface of the control processor. In other embodiments, the control processor is configured to automatically retract the piston when the skin contacting surface head of the device is removed from the body. In perhaps less common embodiments, the piston is retractable manually by a user by pushing or winding down the drive mechanism.

[0045] Fig. 3 is a diagram of an embodiment of the present invention, when charging on a charging base. The skin care device 100 is shown docked on the charging base 195. In this image is also shown the interface 198 of the control processor which allows for a user to choose their skin treatment. In this diagram, the skin care device 100 is shown with the UV sterilisation head (see Fig. 4, 5, 500, 500'). This feature will be discussed in detail below.

[0046] The charging base in some embodiments will also include a power supply. The example power supply may include one or more batteries and / or a connection to a power outlet. The power supply provides power for the skin care device 100 when on the charging base 195.

[0047] Fig. 4 shows the skin care device 100 according to various embodiments. It would be understood by those skilled in the art that the skin contacting surface of the head 190 can be interchangeable based on the desired treatment, given that it is removable to present the cavity for the cartridge. In the "default" or preferred embodiment, the skin contacting surface 190 will comprise heat plates, pulse vibration, electroporation and dual blue / red LEDs. The interface of the control module will allow the user to select their treatment using this skin contacting surface 190, allowing for skin rejuvenation, firming, acne treatment, rosacea treatment, treatment for redness and general serum infusion through electroporation.

[0048] Another embodiment is shown in skin care device 200. This particular skin contacting surface comprises dual wavelength red and infra-red 610 nm - 810 nm lights. The user may use this skin contacting surface for epidermal and dermal skin firming and collagen stimulation.

[0049] Yet another embodiment is shown in skin care device 300. This skin contacting surface comprises a ultrasonic, heat and vibration. This may be used by a user for skin cleansingand exfoliation, and may further comprise a slightly abrasive surface to aid the ultrasonic, heat and vibration features of the skin contacting surface. The skin care device 300 utilises the power of ultrasonic vibrations to perform a deep cleanse of the skin. The device emits high-frequency sound waves that create microscopic vibrations. These vibrations cause the loosening of dirt, oil, and dead skin cells, which are then gently lifted away from the skin's surface. The ultrasonic waves also stimulate blood circulation and promote the production of collagen and elastin, resulting in a firmer and more youthful complexion. The skin scrubber is equipped with a spatula-like metal tip that glides over the skin, effectively exfoliating and removing impurities. The process is painless, non-invasive, and suitable for all skin types.

[0050] Another embodiment is shown in skin care device 400. The skin contacting surface comprises 610 (+ / - 30 nm) LED and 850(+ / - 30nm) nm laser in dual wavelength. The skin contacting surface also comprises acoustic vibration. The user may use this particular head for hair growth and vitality, eczema and psoriasis, vitamin and serum infusion and hair colouring.

[0051] It is envisaged that a user would only need to purchase the skin care device 100 once, and that the skin contacting surface of the heads can be interchanged as shown in 200-500, such that a user may be able to access other treatment surfaces, without necessarily having to replace the whole unit and componentry.

[0052] The skin care device 100 shown in 500 is the UV sterilisation head. This particular head is used after a treatment, and would ideally be sold as part of the base model, so that the user always has access to a means of sterilisation. This UV sterilisation head is releasably engageable like the other skin contact surface components, albeit designed to be used following treatment, and not designed to contact the users skin. The UV sterilisation head also comprises a safety sensor, a timer and an auto switch off for safety reasons. The UV sterilisation head may sterilise other applicators that are in touch with the skin and destroy bacteria and other pathogens that may have been contaminated the head during treatment. The UV sterilisation head is equipped with a magnetic touching sensor that recognises the proper contact of the device to the head and then be activated, to avoid any possible harm of exposing the UV light to the users naked eyes and causing possible eye injuries. The UV head automatically switches off after several minutes.

[0053] Referring now to Fig. 5 is a reproduction of Fig. 4, but showing the various embodiments when in use. The skin care device 100', 200' and 400' is shown with the LEDs, lasers and other features activated when in use by the user.

[0054] Referring now to Fig. 6 is a diagram of the cartridge 130 according to the present invention, with the plunger 140 shown. The plunger 140 is adapted to be engaged by a piston from a driving mechanism. It is envisaged that the user will choose the specific cartridge 130 based on specific skin care requirements, and be able to add this to the skin care device 100 with ease by fitting the cartridge to the skin contacting surface of the head.

[0055] Reference throughout this specification is made to skin care. In general, the skin care refers to the skin on the face of the user. Although, it should be appreciated that the example method and device may be applied to other skin areas, such as a user’s neck, arms, hands, legs, feet, buttocks, chest, under-arm area, back etc.

[0056] The example skin care device can also include a camera, such as a high-resolution camera, an ultraviolet (“UV”) camera, and / or an infrared camera, and a camera light. The example camera and camera light are configured to operate in cooperation to record images of a user’s skin, including lesions, pigments, moles, hair, scars, etc. In addition to the camera, the skin care device can also include a magnifying glass to provide for manual user inspection of their skin.

[0057] The example skin care device can also include a micro-needling pad, equipped with 50-300 needles, ranging from 0.25mm to 2mm in lengths, that could offer needling in a stamping mode to create micro-injuries to the skin, and at the same time infuse skincare or hair care products into the deeper layer of skin, transdermally.

[0058] The example skin care device can also be a UV lamp with wavelengths, ranging from 300nm (+ / -30nm) to 550nm (+ / -30nm) that could treat various types of treatments, such as alopecia areata, Psoriasis, contact dermatitis and Vitiligo.

[0059] The example skin care device can further include one or more LEDs. The example LEDs are configured to emit light at wavelengths that promote skin healing. For example, the LEDs 130 may include LEDs that emit light around 455 nm, light around 633 nm, and / or light around 830 nm. It should be appreciated that the LEDs may emit light at additional or fewer wavelengths.

[0060] The example skin care device can moreover include a vibration actuator, which can include a vibrating pad. As disclosed herein, the vibration actuator can vibrate at one or more frequencies as part of a skin quality assessment and / or a skin treatment. In some instances, the vibration actuator can vibrate at a frequency configured to numb a user’s skin during treatment. In some embodiments, the vibration actuator can be configured to provide vibration via acoustic waves. The actuator can operate at 7,000 (+ / - 500) RPM to generate acoustic waves for inducing tissue vibration.

[0061] To apply skin surface heat, the skin care device includes one or more heat elements. The example heat element is configured to radiate heat up to a temperature between 40°C and 43°C. In other embodiments, the heat element includes a radio transmitter configured to provide localised tissue heating via radiofrequencies or traditional heat ( non-radio frequency). The element can provide heating using a frequency between 100 kHz-300 GHz.

[0062] The example skin care device can also include an iontophoresis or electroporation (EMS)module, which applies a voltage gradient on a user’s skin through the creation of an electric field. The iontophoresis module can be used for transdermal delivery to a user’s skin of a fluid provided in a fluid container. The use of fluid facilitates ionized (charged) particles to traverse the natural barrier provided by the user's skin to thereby enhance absorption and delivery of molecules in the fluid into the skin. In some embodiments the fluid can be a medicament, or an alternative skin treatment fluid, in other embodiments the fluid is a light serum, while in other forms the fluid is a heavier cream or lotion. In these examples, the iontophoresis module is used in conjunction with a fluid dispenser module, which controls dispensing of the fluid from the fluid container.

[0063] By simultaneous multiplexed working action of electroporation or iontophoresis, where electrodes switch between acoustic pulsating energy and low-frequency heat, along with the infusion of a hydrogel-mix composition of the serum containing Carbomer (0.45) and Arginine (0.405) that acts as an energy transmission agent to polarize the serum and facilitate its infusion into the skin’s layers, this maximum energy output delivery can be achieved while minimizing the user’s pain sensation from the sharp sensation of electric discharge. This method efficiently applies high energy density to the treatment area, making it deeper and more tolerable than other personal beauty device technologies on the market.

[0064] In other embodiments, a user can first apply a cream or lotion to their skin, such that subsequent use of the iontophoresis module of the skin care device can promote transdermal propagation of the fluid (cream or lotion) across one or more layers of skin. The iontophoresis or electroporation (EMS) modules can comprise one or a plurality of galvanic plates located about the device and configured for contact with skin of the user.

[0065] The fluid can be selected dependent on the type of treatment to be applied to the user's skin. After skin analysis the device will provide information to the user as to whether a moisturising treatment, a healing treatment, an acne treatment, an aging treatment or scar reduction treatments is recommended. The user can then select the appropriate fluid to be dispensed by the device for the selected treatment

[0066] In some embodiments, the skin care device can include plasma jet control. In these embodiments, a small tip or other attachment can be connected to the device. The tip is controlled by the plasma jet control to generate a plasma for inducing a sublimation process. The process is configured to heat the dermis in a targeted area, which causes peeling and shedding post treatment. The enables new, fresher skin and / or collagen to form.

[0067] The control processor is also configured to transmit signals for activation of the heat element, the vibration actuator, iontophoresis module, the LEDs, the fluid dispenser module, and / or the plasma jet control to perform one or more therapies or treatments.

[0068] The example skin care device 102 of Fig. 1 can also include a user interface 148. In some embodiments, the interface 148 can include one or more buttons 150 or switches, such as a power button 151, a communication pairing button, a record button for manual activation of the camera 126, a light button 155 for manual activation of the camera light 128 and / or LEDs 130, a dispense button 158 for manual dispensing of fluid from the container 140, and / or a start / pause / stop control for beginning, pausing, and stopping a treatment or therapy.

[0069] In some embodiments, as mentioned, the device is adapted to perform skin analysis as described in International Application Number PCT / AU2021050538, the entirety of which is incorporated by reference herein.

[0070] In other embodiments, the device is adapted to perform Bioelectrical Impedance Analysis (BIA) is a non-invasive method that measures the electrical properties of tissues in the body to determine the composition of different body components, such as muscle, fat, and water. BIA works by sending a low-level electrical current through the skin, and measuring how itresponds to the current. The electrical current travels through the different layers of the skin, encountering varying amounts of resistance and impedance, depending on the characteristics of each layer. By measuring the impedance, the device can calculate various skin parameters, including hydration levels, barrier function, elasticity, and more. This technology has been adapted and used in the device to evaluate various skin parameters by using bioelectrical impedance spectroscopy (BIS) or bioimpedance measurements (BIM) for measuring the oil, moisture and texture level of skin within a few seconds.

[0071] It will be appreciated that all of the disclosed methods and procedures described herein can be implemented using one or more computer programs or components. These components may be provided as a series of computer instructions on any conventional computer- readable medium, including RAM, ROM, flash memory, magnetic or optical disks, optical memory, or other storage media.
