Description

Technical Field

[0001] The utility model belongs to the technical field of iontophoresis, and particularly relates to an iontophoresis patch for facial skin. Background Art

[0002] Electroporation is a process in which a transient high-voltage pulsed electric field forms temporary and reversible hydrophilic pores in lipid bilayers such as cell membranes to increase the permeability of cells and tissue membranes. Iontophoresis is a physical process in which an ion current diffuses directionally in a medium under the drive of an electric field force. By applying a fluid containing a charged active ingredient to the skin and covering the fluid with an electrode sheet of an iontophoresis device, while making another electrode sheet contact another skin position of the body, the charged active ingredient is driven to rapidly penetrate into the skin under the energized state by using the principle of like charges repelling each other, thereby achieving the purpose of transdermal drug delivery in the medical field or the purpose of skin care in the beauty field. However, iontophoresis introduction devices usually use devices with handles to move around on the skin surface, resulting in low introduction efficiency and inconvenient operation.

[0003] In recent years, beauty instrument products and technologies presented in the form of electronic masks have developed relatively rapidly. Existing electronic masks use silicone and rubber thin sheets as the base. Since such materials cannot adsorb beauty essence, it can only be coated on the surface of the base, resulting in a small amount of essence carried by the electronic mask and affecting the beauty effect.

[0085] In the above-described embodiment, the wire layer 42 and the first electrode 3 are connected by the joint 43 made of conductive graphite or conductive carbon paste, which can effectively prevent the connection between the wire layer 42 and the first electrode 3 from being exposed and contaminated with beauty essence or medicine solution, resulting in oxidation and electrolysis reactions, thereby effectively avoiding the contamination of beauty essence or medicine solution. Moreover, the wire layer 42 is insulated and wrapped by the bottom layer 41 and the covering layer 44, and the electric energy is directly conducted to the middle part of the first electrode 3.

[0092] and / or, the material of the bottom layer 41 is at least one of polyurethane, acrylate, epoxy resin, and polyamide resin.

However, when silver is exposed to beauty essence or medical drug solution and a positive electrode is connected, electrolytic reaction may occur to the silver wire, releasing silver ions, thus increasing the product use risk. Wrapping the wire layer 42 with the underlying layer 41 and the covering layer 44 that are both insulating layers, and simultaneously using the joint 43 made of conductive graphite or conductive carbon paste as the printing material to connect the exposed first electrode 3 can effectively prevent the exposure of the silver conductor.

[0097] Optionally, a decorative layer can be provided on the surface of the covering layer 44. This helps to improve the aesthetics of the iontophoresis patch.
