Description

Technical Field

[0001] This utility model relates to a roller microneedle kit. Background Technology

[0002] With the changing pace of life, more and more people are paying attention to beauty and health maintenance, especially women, who are particularly focused on skin care, which mainly involves whitening, wrinkle removal, and freckle and scar removal.

[0003] Currently available skincare products typically involve applying serums or masks. These methods offer limited and slow-acting results, and the nutrients in these products only remain on the skin's surface, making absorption difficult. Several technologies allow for direct skin absorption. One is microneedling, which delivers nutrients directly to the skin through microneedles. However, controlling the nutrient solution on the microneedles during this process is challenging. Thread lifting, often marketed as a treatment, uses threads that are merely decorative and ineffective, often made from recycled silk waste, which not only lacks benefits but can also cause skin damage. Another method is ultrasonic thread lifting, which uses ultrasound to treat the skin. While ultrasound can effectively and quickly reach skin cells, it is difficult to control and can damage healthy cells in the process.

[0004] Meanwhile, traditional microneedles are made of metal materials using traditional processes. However, most microneedle arrays and microneedle sheets that have appeared on the market in the past decade are made using new technologies. These new technologies employ ultra-micro processes and use materials such as monocrystalline silicon, medical alloys, and polymer materials to create smaller microneedles. They are widely used in the beauty industry and, when used in conjunction with cosmetic or medical device liquid products, have achieved significant social and economic benefits.

[0056] The microneedles 202 are tipless and have a height of 50-600 μm; the bottom diameter of the microneedles is 50-300 μm, and the top diameter is 1-100 μm. The substrate 201 and microneedles 202 are primarily composed of monocrystalline silicon, medical alloy materials, and polymer materials. The substrate 201 not only serves as a carrier for the microneedles 202 but also as a carrier for nutrient solutions, allowing for direct application to the skin and enhancing its cosmetic and skincare effects.

[0057] Meanwhile, the substrate 201 can also be made of hyaluronic acid, silk fibroin, or other functional nutrient solutions, allowing for direct absorption by the skin and resulting in a lifting and firming effect. Furthermore, it can be used in conjunction with various functional skincare products, such as those for acne treatment, anti-wrinkle, whitening, and breast enhancement. The substrate not only serves as a carrier for microneedles but also allows the nutrient solution to act directly on the skin, penetrating directly into the skin.

[0058] Since microneedles 202 are added to the substrate 201 provided in this embodiment of the utility model, the microneedles 202 can directly enter the skin, which helps the nutrients penetrate into the dermis layer of the skin, further aiding absorption and providing beauty and skin care effects.

The spacing between adjacent microneedles 202 is 0.6 mm. The microneedles 202 are arranged in an array on the substrate 201, with a total of eight rows. When the user directly applies the microneedles to the skin and gently presses them, the nutrient solution begins to enter the skin.

[0081] Compared to traditional beauty and skincare products, where beauty serums enter the skin's surface through small pores, this invention directly introduces the beauty serum into the skin's surface. This not only improves the efficiency of beauty treatments but also prevents the serum from being contaminated by external factors, allowing for the direct and hygienic introduction of uncontaminated beauty serum into the skin.

An opening is provided on the reverse side wall of the connecting part 304, communicating with the aromatherapy-releasing cavity. A sealing door 313 is provided on the reverse side wall of the connecting part 304 at the opening location, sealing the opening and facilitating the removal of the aromatherapy-releasing object from the aromatherapy-releasing cavity. An aromatherapy release through-hole 314 can be provided on the sealing door 313, releasing aromatherapy outwards, thus greatly improving the user's beauty experience. Furthermore, to facilitate opening and closing the sealing door 313, a handle 315 can be provided on one side of the outer wall of the sealing door 313, allowing for easy operation of opening and closing. Of course, the aroma release hole 314 can also be set in other locations, such as on the front side wall of the connecting part 304 below the thumb pressing recess 312, or on the front or rear side wall of the connecting plate 303 or on the lower side wall near the roller 100.

[0084] The roller microneedle kit provided in this embodiment can also be used in conjunction with an injection container. Specifically, a through hole 319 can be provided in the connecting part 304, that is, the upper end of the through hole 319 extends to the top side of the connecting part 304, and the lower end of the through hole 319 extends to the bottom surface of the connecting plate 303; at the same time, an injection container 316 is installed at the top of the connecting part 304.
