Hydrocolloid wrinkle patch

Abstract

A hydrocolloid wrinkle patch having a repairing effect, consisting of a hydrocolloid adhesive-coated substrate (1), an absorbent pad (2), and a peelable protective layer (3). The absorbent pad (2) is made from an adhesive hydrocolloid capable of absorbing moisture. The hydrocolloid mainly consists of gelatin, carboxymethyl cellulose, and other absorbent materials. In this way, the user comfort is improved, the application time is extended, and the use experience is improved.

Description

A hydrocolloid wrinkle patch TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, personal care products, and in particular, to a hydrocolloid wrinkle patch. The wrinkle patch is improved through new materials and technology to enhance user experience. BACKGROUND

[0002] There are three main reasons for the formation of facial wrinkles: facial activity, facial dehydration, and loss of facial collagen. Wrinkle patches are mainly aimed at wrinkles caused by facial activity, such as glabella lines, marionette lines, and crow's feet. TECHNICAL PROBLEM

[0003] Currently, wrinkle patches on the market that target such wrinkles are mainly divided into two categories:

[0004] 1. Local anti-wrinkle masks: mainly play a role in hydrating and relieving wrinkles, and the mask is applied for generally no more than 20 minutes, with limited effect in a short period of time and high cost.

[0005] 2. Wrinkle stickers: used at night, and relieve the further formation of wrinkles caused by facial movement through physical fixation. However, due to less facial muscle activity at night, wrinkles still cannot be avoided during the day. In addition, such products may also cause skin allergies, poor breathability, certain irritation to the skin, and poor comfort.

[0006] Both of the above two types of wrinkle patches have obvious defects and technical deficiencies. TECHNICAL SOLUTION

[0007] In view of the deficiencies of the prior art, the purpose of the present application is to provide a hydrocolloid wrinkle patch that changes the local activity of the face and the microenvironment of the local skin, thereby improving the skin condition and relieving the formation of wrinkles.

[0008] The technical solution of the present application is as follows: a hydrocolloid wrinkle patch with a repairing effect, characterized by being composed of a hydrocolloid adhesive base material, an absorbent pad, and a peelable protective layer, which can increase the anti-adhesion layer to avoid leaving adhesive on the face after use. The absorbent pad is made of a water-absorbing adhesive hydrocolloid, and the hydrocolloid is mainly composed of gelatin, carboxymethyl cellulose (CMC), and other absorbent materials. ADVANTAGEOUS EFFECTS

[0009] The beneficial effects of the present application are:

[0010] 1. Fully utilizing the absorbency of hydrocolloids, it absorbs moisture released by the skin, creating a stable moist environment and low oxygen tension, promoting local blood circulation and improving the microenvironment. The semi-permeable membrane is waterproof and breathable, thereby improving comfort, extending the application time, and allowing wrinkled skin to fully rest and recover its original state. Depending on the absorbency of the wrinkle patch, it can be continuously worn for up to 72 hours.

[0011] 2. The overall strength of the wrinkle patch can fix the skin in the wrinkled area of ​​the face. Due to its thin, transparent and comfortable characteristics (minimum thickness can be 0.1mm), it can be used during the day without affecting appearance or makeup. It can prevent local skin movement all day long and prevent wrinkles from deepening due to movement.

[0012] 3. Other nutrients beneficial to skin recovery can be added, such as soluble microneedles (CN209316551U), to further enhance the skin recovery effect. Attached Figure Description

[0013] Figure 1 is an exploded structural diagram of the present invention; Figure 2 is a cross-sectional structural diagram of the present invention; Figure 3 is a schematic diagram of the use of the present invention.

[0014] The labels in the diagram are as follows: ① is the adhesive substrate, ② is the hydrocolloid absorbent pad, ③ is the peelable protective layer, and ④ is the hydrocolloid wrinkle patch. The best embodiment of the present invention

[0015] The following is an overview of the general manufacturing process of hydrocolloid wrinkle dressings:

[0016] 1. Raw material selection: The basic components of hydrocolloid wrinkle patches usually include gelatin, carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA), sodium polyacrylate, etc. These are highly absorbent materials that can swell and form a gel after contacting the skin and exuding sweat or other moisture.

[0017] 2. Mixing and Preparation: Mix the above ingredients evenly in a certain proportion, and ensure the materials are fully integrated by heating, stirring, or other methods. Sometimes, auxiliary ingredients such as antioxidants and antibacterial agents are added to enhance the product's performance.

[0018] 3. Shaping: The mixed material is spread into a film or sheet, and then cooled and set. During this process, the material forms a soft and elastic layer that adheres to the skin and absorbs moisture released by the skin.

[0019] 4. Backing Material Addition: One or more layers of backing material, such as polyurethane foam, nonwoven fabric, or other breathable materials, are attached to one or both sides of the hydrocolloid layer. The backing material has a certain degree of breathability, allowing oxygen to enter the wound while preventing bacteria, water, and dirt from entering. The final product thickness is between 0.1-3 mm.

[0020] 5. Cutting and packaging: The finished product is cut into different shapes and sizes as needed, and sealed for packaging to maintain its effective state until use.

[0021] 6. Quality testing: After production, each batch of product will undergo strict testing, including but not limited to sterility testing, absorption performance testing, etc., to ensure that the product meets the factory standards and even medical standards. Embodiments of the present application

[0022] The use method of the hydrocolloid wrinkle patch is to directly apply it to the wrinkled skin area. The wrinkle patch is light, breathable, and can be used for makeup, invisible, and can be applied all day to fix the wrinkled skin area and give the skin sufficient rest time and recovery status. The use method is shown in detail in FIG. 3.

[0023] The implementation cases of the specific embodiments are effective implementation cases of the present application, and do not limit the protection scope of the present application. Any equivalent changes made according to the structure and principle of the present application are also covered by the protection scope of the present application. Industrial applicability

[0024] In terms of production and manufacturing, the acquisition of hydrocolloid materials is relatively easy, and the production process is mature, which can realize large-scale and high-efficiency production. Moreover, the quality control in the production process is relatively simple, and the cost is controllable, which is conducive to reducing production cost and improving market competitiveness of the product.

[0025] In terms of market demand, with the increasing demand for comfort and safety of medical supplies, this new product, which can effectively solve many problems of traditional wrinkle patches, has great market potential. Whether it is a medical institution or an individual consumer, there is a strong demand for wrinkle patches with good skin friendliness and low pain.
