Hyaluronic acid hydrogels (HAHs) were synthesized by immersing the HA microbeads crosslinked with divinyl sulfone in phosphate buffered saline solution to assess the responses of tissues to the implant by means of the subchronic systemic toxicity and the intradermal implant test. The HAHs, prepared by the microbeads with an average diameter of 140 μm and a(More)

The fillers consist of crosslinked HA microspheres suspended in a noncrosslinked HA. To extend the duration of HAs within the dermis and obtain the particle texturing feel, HAs are(More)
