Dental pulp stem cells are mixed with the HA hydrogel and injected into the damaged pulp using a syringe. The HA hydrogel provides a suitable microenvironment for the proliferation and differentiation of dental pulp stem cells, leading to functional dental pulp tissue regeneration. In addition to dental pulp regeneration. B HA hydrogel can be incorporated into skincare products, such as creams and serums, to improve skin hydration and reduce the appearance of fine lines and wrinkles. HA hydrogel can also be used as a filler in facial rejuvenation procedures, providing immediate volumization and contouring [Figure generated using https://www.biorender.com/].
