the present invention provides a microstructure that includes the crosslinked hyaluronic acid hydrogel, and a method for producing it. the present invention has an effect in which it is possible to produce a microstructure that is uniform and has minimized distortion, since the microstructure of the present invention uses the crosslinked hyaluronic acid hydrogel. in addition, the microstructure of the present invention, which uses the crosslinked hyaluronic acid hydrogel, has the advantages of: being able to improve aged skin tissue, such as wrinkles, and providing a moisturizing effect to it; easily absorb body fluid into a living body due to its excellent swelling properties; and being able to stably distribute the useful components in the living body due to the stability of hyaluronidase and, as a result, the duration of the microstructures within the living body being long. |
