Hydrocolloid wrinkle patch

Abstract

The invention provides a hydrocolloid wrinkle patch, belongs to the technical field of medical instruments and personal care products, and aims at solving the problems that an existing wrinkle patch is uncomfortable to patch and long in service time. Due to the skin-friendly property of the hydrocolloid and the waterproof and breathable properties of the polymer semi-permeable membrane, the use time of the wrinkle patch is longer, the hydrocolloid wrinkle patch can contain beauty components or medical beauty components, and the use experience of a user is improved.

Description

Technical Field

[0001] The present invention relates to the field of medical devices and the technical field of personal care products, and in particular to a hydrocolloid wrinkle patch. The wrinkle patch is improved by new materials and technologies to enhance the user experience. Background Art

[0002] There are three main reasons for the formation of facial wrinkles: facial activities, facial dehydration, and facial collagen loss. Wrinkle stickers are mainly used to treat wrinkles caused by facial activities, such as frown lines, nasolabial folds, crow's feet, etc.

[0003] Currently, wrinkle stickers for this type of wrinkles on the market are mainly divided into two categories:

[0004] 1. Local anti-wrinkle mask: It mainly plays the role of moisturizing and alleviating wrinkles. The mask application time is generally not more than 20 minutes. The effect is limited in a short period of time and the cost is relatively high.

[0005] 2. Wrinkle stickers: Used at night, they can alleviate the further formation of wrinkles caused by facial movements through physical fixation. However, since facial muscles are less active at night, wrinkles cannot be avoided during the day. In addition, this type of product may cause skin allergies, has poor breathability, is irritating to the skin, and is not comfortable.

[0006] Both of the above types of wrinkle stickers have obvious defects and technical deficiencies. Summary of the invention

[0007] In view of the deficiencies in the prior art, the purpose of the patent application of the present invention is to provide a hydrocolloid wrinkle patch that changes local facial activities and local skin microenvironment, thereby improving skin conditions and alleviating the formation of wrinkles.

[0008] The technical solution of the present invention is as follows: a hydrocolloid wrinkle patch with repairing effect, characterized by being composed of a hydrocolloid glue-coated substrate, an absorbent pad and a peelable protective layer, which can add an anti-adhesion layer to avoid leaving glue on the face at the end of use. The absorbent pad is made of a viscous hydrocolloid that can absorb water, and the hydrocolloid is mainly composed of gelatin, carboxymethyl cellulose (CMC) and other absorbent materials.

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

[0010] 1. Make full use of the absorbency of hydrocolloids to absorb the water released by the skin, form a stable humid environment and low oxygen tension, promote local blood circulation, and improve the microenvironment. The semi-permeable membrane is waterproof and breathable, thereby improving comfort and extending the application time, so that the wrinkled skin can get enough rest and restore its original state. According to the water absorption degree of the wrinkle patch, it can be applied continuously for up to 72 hours.

[0011] 2. The overall strength of the wrinkle patch can fix the skin in the wrinkled areas of the face. Due to its light, transparent and comfortable characteristics (the minimum thickness can reach 0.1mm), it can be used during the day without affecting the appearance or makeup. It can prevent local skin movement around the clock and prevent the deepening of wrinkles caused by exercise.

[0012] 3. Other nutrients that are beneficial to skin recovery can be added, such as soluble microneedles (CN209316551U), to further enhance the skin recovery effect. BRIEF DESCRIPTION OF THE DRAWINGS

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

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

[0017] 2. Mixing and preparation: Mix the above ingredients in a certain proportion and ensure that the materials are fully integrated by heating and stirring. Sometimes some auxiliary ingredients such as antioxidants and antibacterial agents are added to enhance the performance of the product.

[0018] 3. Molding: Spread the mixed material into a film or sheet, and then cool it to set. During this process, the material will form a soft and elastic layer that can fit the skin and absorb the moisture released by the skin.

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

[0020] 5. Cutting and packaging: Cut the finished product into different shapes and sizes as needed and seal it to keep it in effective condition until use.

[0021] 6. Quality inspection: After production is completed, each batch of products will undergo strict testing, including but not limited to sterility testing, absorption performance testing, etc., to ensure that the products meet factory standards and even medical standards.

[0022] The method of using this hydrocolloid wrinkle patch is to apply it directly to the wrinkled skin. The wrinkle patch is thin and breathable, can be worn with makeup, and is invisible. It can be applied all day long to fix the wrinkled skin area and give the skin enough time to rest and recover. For a detailed diagram of the method of use, see Figure 3 .

[0023] The implementation cases of this specific implementation method are all effective implementation cases of the patent of the present invention, and do not limit the protection scope of the patent of the present invention in turn. All equivalent changes made based on the structure and principle of the patent of the present invention are covered within the protection scope of the patent of the present invention.
