High-molecular soluble microneedle and production method thereof

Abstract

The invention discloses a high-molecular soluble microneedle and a production method thereof. The high-molecular soluble microneedle is composed of a needle body and a substrate; the needle body is composed of hyaluronic acid, polyglutamic acid, tremella polysaccharide, vitamin C ethyl ether, oligopeptide-1, oligopeptide-3, oligopeptide-5, cannabidiol, arbutin, rhodiola rosea extract, vitamin E, ginseng extract, radix sophorae flavescentis extract, pseudo-ginseng extract, rose essential oil, trehalose, polyvinyl alcohol, polyvinylpyrrolidone, soluble starch, glycerol and water; and the substrate is composed of polyvinyl alcohol and water. The production method of the microneedle comprises the following steps: weighing the components in parts by weight, respectively carrying out vacuum stirring dissolution on the components of the needle body and the substrate, carrying out high-pressure molding on the needle body part through a mold and a high-pressure device, coating the mold with a vacuum stirring dissolution solution of the substrate, and carrying out freeze drying to obtain the microneedle. The product is good in penetrability, safe, reliable and convenient to use; the production method is simple, time-saving and high in feasibility.

Description

technical field [0001] The invention relates to a microneedle and a production method thereof, in particular to a polymer soluble microneedle and a production method thereof. Background technique [0002] Nowadays, beauty products and technologies on the market are mixed. For women who love beauty, on the one hand, they are afraid of the high risks of medical beauty. Reliable and high-efficiency methods occupy an increasingly important position in the beauty field; however, traditional microneedles are insufficient in injection quality, penetration and penetration density, and are very effective in solving skin water-locking, fine lines, and dry lines. The effect of equal-depth problems is not significant enough, which increases the beauty cycle and cost; micro-needle beauty is a medical beauty project, which requires strict operation by beauty technicians in regular beauty institutions. The needle operation process has not been simplified and is still very cumbersome. Ther...

[0002] Nowadays, beauty products and technologies on the market are mixed. For women who love beauty, on the one hand, they are afraid of the high risks of medical beauty. Reliable and high-efficiency methods occupy an increasingly important position in the beauty field; however, traditional microneedles are insufficient in injection quality, penetration and penetration density, and are very effective in solving skin water-locking, fine lines, and dry lines. The effect of equal-depth problems is not significant enough, which increases the beauty cycle and cost; micro-needle beauty is a medical beauty project, which requires strict operation by beauty technicians in regular beauty institutions. The needle operation process has not been simplified and is still very cumbersome, so there is an urgent need for a micro-needle beauty product with high efficacy and easy use in the market
