The present invention provides a microstructure comprising a cross-linked hyaluronic acid hydrogel and a method for producing the same. According to the present invention, the microstructure of the present invention can produce a microstructure that is uniform and minimized in warpage by using crosslinked hyaluronic acid hydrogel. In addition, the microstructure using the crosslinked hyaluronic acid hydrogel of the present invention can improve the aged skin tissue such as wrinkles and give a moisturizing effect, and is excellent in swelling property to easily absorb body fluids in vivo, And the microstructure has a long duration in vivo, so that there is an advantage that the useful component can be stably transmitted in vivo. |
