[0002] With the development of the beauty industry, there are many types of beauty devices on the market, among which electrode-type beauty devices are widely favored for their effectiveness. Electrode-type beauty devices use electrodes to transmit current, thereby stimulating muscle contraction to tighten the skin and opening skin channels to promote the absorption of beauty serums.

[0003] However, current electrode-based beauty devices have design flaws. The electrode layout is often too simplistic, and the polarity and spacing between electrodes lack scientific design. This results in poor uniformity of the electric field distribution, making it impossible to provide targeted stimulation to different layers of the skin, significantly reducing the beauty effect and failing to meet the diverse skincare needs of users.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0044] Please refer to Figure 1 This utility model provides a beauty device, including a base and an electrode assembly disposed on the base.

[0045] The portion of the substrate that comes into direct contact with the skin to be treated provides the mounting base and structural support for the electrode assembly.

[0046] Specifically, the electrode assembly includes an inner electrode group 10 and an outer electrode group 20. The inner electrode group 10 has at least two concentric inner electrodes arranged in a ring around the center; the outer electrode group 20 includes at least one outer electrode surrounding the outer side of the inner electrode group 10.

[0047] In the inner electrode group 10, two adjacent inner electrodes have a first spacing; at the same time, there is a second spacing between the outer electrode and the inner electrode, and the first spacing is smaller than the second spacing.

[0048] Understandably, when the polarities of the inner electrode group 10 are opposite and the polarities of adjacent outer and inner electrodes are opposite, the spacing between the inner electrode groups 10 is smaller, the current density is higher, and the depth of action on the skin is shallower, allowing for stronger stimulation of the superficial skin. Conversely, the spacing between adjacent outer and inner electrodes is larger, the current density is lower, and the depth of action on the skin is deeper, allowing for gentler stimulation of the deeper skin. Through the aforementioned spacing settings, a layered electric field intensity distribution can be created on the skin surface. When the beauty device moves regularly on the skin, each area can receive both deep and superficial care, which is beneficial for achieving diversified care effects.

[0049] In some embodiments of this invention, the beauty device further includes a current output control module disposed on the substrate.

[0050] The current output control module is electrically connected to the electrode assembly and is used to output a predetermined current in a predetermined current output sequence within each output cycle T.

[0051] Specifically, the current output sequence is alternating current followed by direct current. The outer electrode group 20 and the inner electrode group 10 have opposite polarities and form a circuit to output both alternating current and direct current. Under this current output sequence, the characteristics of alternating current and direct current can be combined to create a complex stimulation to the skin, thereby enhancing the cosmetic effect, such as promoting nutrient penetration, lifting and firming the skin, and promoting collagen regeneration.

[0052] In this embodiment, because the outer electrode group 20 and the inner electrode group 10 have opposite polarities, the direction of the electric field lines can remain relatively uniform when the electrodes of the beauty device act on the skin. This stable direction of the electric field lines avoids discomfort to the skin caused by current disturbances. At the same time, combined with the alternating current-to-direct current output sequence, it allows users to experience gentle comfort and receive continuous and effective care during the beauty process, significantly improving user comfort and satisfaction.

[0053] In other embodiments of this example, the beauty device further includes a conductive component and a current output control module disposed on the substrate. The conductive component and the electrode component are respectively disposed on different surfaces of the substrate. The current output control module is electrically connected to the conductive component and the electrode component respectively, and is used to control the beauty device to output a predetermined current in a predetermined current output sequence within each output cycle T.

[0054] Specifically, the current output sequence is AC current - DC current.

[0055] When the beauty device outputs alternating current, the outer electrode group 20 and the inner electrode group 10 have opposite polarities and form a circuit; when the beauty device outputs direct current, the outer electrode group 20 and the inner electrode group 10 have the same polarity, and the polarity of the conductive component is opposite to that of the outer electrode group 20 and the inner electrode group 10 and forms a circuit.

[0056] Understandably, in this embodiment, the conductive component is located on the part of the substrate that the user holds. When the user performs skin care using the beauty device, the user's hand contacts the conductive component, and the skin to be treated contacts the electrode component. When the beauty device needs to output direct current, the outer electrode group 20 and the inner electrode group 10 form a combined electrode. The polarity of the conductive component is opposite to that of the combined electrode, forming a circuit to achieve ion export or ion import functions. When the beauty device needs to output alternating current, the polarities of the outer electrode group 20 and the inner electrode group 10 are opposite, forming a circuit to achieve functions such as nutrient penetration, lifting and firming, and promoting collagen regeneration. Under the time-sharing alternating output of alternating and direct current, a complex stimulation is formed on the skin, enhancing the beauty effect. Moreover, in this embodiment, since the outer electrode group 20 and the inner electrode group 10 acting on the skin to be treated have the same polarity, the effective area for ion import or ion export on the skin to be treated is increased, thereby increasing the effect of introducing nutrients into the skin or removing impurities.

[0057] Similarly, in this embodiment, since the outer electrode group 20 and the inner electrode group 10 have opposite polarities, the direction of the electric field lines can remain relatively uniform when the electrode assembly of the beauty device outputs alternating current to the skin, allowing the user to feel gentle and comfortable during the beauty process.

[0058] In this embodiment, the current output sequence includes several combinations:

[0059] 1) EMS current — iontophoresis current — electroporation current — iontophoresis current.

[0060] Please refer to Figure 2 The waveforms are for three types of current.

[0061] In this embodiment, the output control module of the beauty device electrode assembly can cyclically output three waveforms. When outputting in the order of "EMS-ion-electroporation-ion...", "ion-electroporation-ion" is the key combination.

[0062] First, ions are used to allow the beauty serum to initially penetrate the skin. Then, electroporation creates absorption channels in the skin, and finally, ions are used again to further penetrate the substance along these channels. EMS current, on the other hand, directly stimulates muscles, causing them to contract and regain elasticity, resulting in firmer skin. Furthermore, the microcurrent loosens the connections between stratum corneum cells, making the stratum corneum structure more porous and reducing resistance to substance penetration, thus enhancing the effectiveness of subsequent iontophoresis and electroporation.

[0063] Furthermore, EMS can stimulate microvessels in the skin, causing vasodilation and promoting blood circulation. This delivers more nutrients and oxygen to skin cells while removing metabolic waste. On the one hand, this helps maintain the normal physiological functions of skin cells; on the other hand, it creates a more favorable environment for the penetration of substances. When skin microcirculation is improved, skin metabolism accelerates, and the skin's ability to absorb external substances is further enhanced.

[0064] 2) EMS current—iontophoresis current—electroporation current.

[0065] In this cyclical mode, EMS current is first used to stimulate muscles and improve firmness; then, iontophoresis current carries nutrients into the skin to replenish cells; finally, electroporation current is used to increase cell permeability so that nutrients can enter cells more deeply.

[0066] 3) Electroporation current—Ion implantation current—EMS current.

[0067] In this cyclical mode, electroporation current is first used to create pores in the cell membrane, opening channels for nutrients; then, iontophoresis current is used to deliver a large amount of nutrients into the cells; finally, EMS current is used to stimulate muscles and promote metabolism, thereby further enhancing skin firmness.

[0068] These different combinations can meet the needs of different users. For example, for users who want to improve skin firmness, EMS current can be used to stimulate muscles first, followed by iontophoresis current to promote the absorption of beauty products, and then electroporation current can be used to open skin channels to further enhance the absorption effect.

[0069] In this embodiment, the duration of each predetermined current has different combination ratios:

[0070] 1) When the current is output in the order of EMS current - iontophoresis current - electroporation current, or electroporation current - iontophoresis current - EMS current, the duration of each predetermined current within each output cycle T follows the following proportional relationship:

[0071] The relationship is t1:t2:t3 = 4:1:3;

[0072] Where t1 is the total duration of EMS current, t2 is the total duration of iontophoresis current, and t3 is the total duration of electroporation current.

[0073] In this approach, the EMS current lasts for a longer duration, allowing for deeper stimulation of muscle tissue and prompting frequent muscle contractions and relaxations. Prolonged EMS current stimulation effectively enhances muscle vitality, improves skin firmness, and significantly reduces wrinkles and sagging caused by muscle relaxation. Furthermore, the extended duration of EMS stimulation can more effectively reduce the resistance of the stratum corneum to substance penetration.

[0074] The shortest duration of iontophoresis current is used to deliver beauty essences into the skin, providing a nourishing effect. Subsequently, electroporation current is used to open the microchannels of the stratum corneum, further promoting the penetration and absorption of beauty products, enhancing the deep nourishing effect, and improving skin texture at the cellular level.

[0075] The electroporation current has a moderate total duration of action, which can effectively improve skin permeability. Combined with the product's absorption, it allows nutrients to enter cells more effectively.

[0076] Therefore, at this cycle length ratio, the skin can be tightened better in a shorter time, while promoting the skin's absorption of nutrients.

[0077] 2) If the output is in the order of EMS current – ​​iontophoresis current – ​​electroporation current – ​​iontophoresis current, the duration of each predetermined current follows the following proportional relationship:

[0078] t1:t2:t3 = 2:1:1.5.

[0079] Where t1 is the total duration of EMS current, t2 is the total duration of iontophoresis current, and t3 is the total duration of electroporation current.

[0080] A longer EMS current application time can more effectively stimulate muscles and reduce the resistance of the stratum corneum to substance penetration. The iontophoresis current application time t2 is longer than the combination mentioned in 1), further enhancing nutrient delivery. The electroporation current application time t3 is moderate, allowing for more complete formation of pores in the cell membrane, greatly improving skin permeability and enabling a large amount of nutrients to enter the cells. While improving skin firmness, it also has a significant effect on promoting skin absorption of nutrients and restoring vitality.

[0081] 3) Taking the sequence of EMS current—iontophoresis current—electroporation current—iontophoresis current as an example, the relationship between the output period T and the duration of each predetermined current is as follows:

[0082] T = t4 + t5 + t6 + t7, where t4 is the duration of the EMS current, t5 is the duration of the first iontophoresis current, t6 is the duration of the electroporation current, and t7 is the duration of the second iontophoresis current.

[0083] Under this formulation, EMS current for duration t4 first stimulates muscle contraction, laying a foundation for skin firmness and reducing the resistance of the stratum corneum to substance penetration; then, iontophoresis current is applied in t5 to initially guide nutrients into the skin; then, electroporation current is applied in t6 to increase cell permeability; finally, iontophoresis current for duration t7 plays a role again, allowing more nutrients to penetrate deeper into cells based on increased cell permeability, achieving efficient nutrient delivery and absorption, and comprehensively enhancing the beauty effect.

[0084] Furthermore, when Scheme 1) or Scheme 2) is combined with Scheme 3), it is beneficial to ensure the synergistic effect of various currents.

[0085] Furthermore, in another implementation, based on scheme 1) or scheme 2), or a combination of scheme 1) or scheme 2) and scheme 3), within each output cycle T, the EMS current is output in the order of 2 seconds, the iontophoresis current is output in 0.5 seconds, and the electroporation current is output in 1.5 seconds, and the predetermined current cycle duration within each output cycle T is 5 minutes. This precise timing control ensures that the various currents exert their effects without causing excessive stimulation to the skin.

[0086] In this embodiment, the aforementioned control of the current output time can fully leverage the cosmetic effects of different currents. By allowing the EMS current to act for a certain duration, sufficient stimulation and training of the muscles can be ensured, enabling muscle cells to produce ATP, enhancing cell activity and metabolism, thereby guaranteeing the optimal environment for subsequent iontophoresis and electroporation currents. Because electroporation requires sufficient time to open skin channels, while ions can move rapidly under the influence of an electric field—meaning ions can complete their movement within the skin channels in a relatively short time—the duration of the electroporation current needs to be longer than that of the iontophoresis current.

[0087] Understandably, the frequency of EMS current is lower than that of electroporation current. To achieve the aforementioned effects, the duration of EMS current application needs to be longer than that of electroporation current. Therefore, by first using electroporation current to briefly open pores, and then relying on EMS current to maintain cell state for a longer period, nutrients can be continuously delivered to the skin and fully absorbed. This achieves a highly efficient synergistic effect, enhancing the penetration and absorption of nutrients in the beauty serum, thereby comprehensively improving the beauty results.

[0088] Specifically, in this embodiment, the EMS current output by the output control module has a frequency range of 12.5Hz-125Hz. It is understood that human muscle contraction is controlled by nerve signals, which are essentially electrical signals. When the EMS current frequency is within the aforementioned range, it can simulate the natural electrical signals of the human body, thereby matching the electrical characteristics of muscle cells. This effectively stimulates the opening of ion channels on the muscle cell membrane, causing changes in the ion concentration inside and outside the cell, triggering excitation of the muscle cells, and ultimately leading to muscle contraction. Based on this, the EMS current within this frequency range can effectively stimulate muscle contraction, ensuring a firming effect while maintaining a balanced user experience.

[0089] The electroporation current frequency range is 2.5kHz-3.5kHz. The cell membrane, which acts as a barrier layer, is composed of a phospholipid bilayer. When the electroporation current acts on the skin at a frequency of 2.5kHz-3.5kHz, the generated high-frequency electric field can cause the phospholipid molecules on the cell membrane to rearrange, forming micropores. This allows nutrients in the beauty serum to more easily pass through the cell membrane and enter the cell, greatly improving the skin's absorption efficiency of nutrients.

[0090] In this embodiment, the area ratio of the inner electrode group 10 to the outer electrode group 20 is controlled within the range of 1:0.7 to 1:1.1. Within this area ratio range, the areas of the positive and negative electrode groups are relatively close, allowing energy to be distributed relatively evenly in the skin area between the two electrode groups, making the user feel more comfortable and providing a gentler and more uniform stimulation throughout the treatment process. This ratio setting helps optimize the electric field distribution, making the current more evenly distributed on the skin surface and avoiding uneven electric field caused by excessive differences in electrode area, thereby ensuring the stability and effectiveness of the beauty device during iontophoresis, iontophoresis, and other beauty functions.

[0091] In one embodiment of this invention, the inner electrode group 10 includes two layers of annular single-electrode units, with the geometric centers of the two annular single-electrode units coinciding. This concentric annular design further enhances the stability and uniformity of the electric field in the inner electrode group 10.

[0092] Please refer to Figure 3 Between the inner electrode group 10 and the outer electrode group 20, at least one layer of outer electrode group 30 is also provided, and the outer electrode group 30 is used for external resistor connection.

[0093] By setting a secondary outer electrode group 30 between the outer electrode group 20 and the inner electrode group 10 and connecting it to an external resistor, the problems of dispersed current distribution, reduced current density, and uneven electric field caused by large electrode spacing are effectively solved. On the one hand, this avoids the new unevenness of energy and stimulation that arises after adding electrodes, making the current density and stimulation effect in each area more consistent, achieving uniform stimulation, and improving user comfort. On the other hand, it improves the uniformity of the electric field, making up for the original deficiency of poor electric field uniformity, thereby improving the overall effect of the electrodes and better meeting the personalized needs of different users for beauty effects.

[0094] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
