Can I inject Hyaluronic acid if their are tiny bubbles in the syringe, during that won't go away?

If you need to ask this question, you obviously should not be injecting any fillers into yourself or anyone else.

In my opinion, if you don't know the answer to this question you shouldn't be injecting hyaluronic acid.

You're not injecting into vessels so it may be OK.The most prudent thing to do is to discard it and use a new syringe of product without such bubbles.Best,Dr Karamanoukian
