Filler.

What the gurus are saying

The gurus who weighed in express caution. One expert questions whether hyaluronic acid filler delivers meaningful results, even in the short term. Another notes that while the body can regenerate nerve tissue after filler is dissolved, the process is very slow, and if nerves have been damaged by the filler itself, that becomes a serious concern. That means anyone considering this filler may want to have a detailed conversation with their injector about the risks to nerve function and realistic timelines for results.
