If you are allergic to one type of hyaluronic acid filler, does that mean you are allergic to all types?

Thank you for your great question. It is possible to have reactions that can resemble allergic reactions, but can be infectious or inflammatory in nature instead. In our practice with situations like these, we will cleanse a small area in the forearm, inject a small amount of a different dermal filler, and observe for any reaction. If no reaction, we proceed with injections. Our offices have the necessary protocols, medication, and supplies present in the event of allergic reaction.

To make this simple, you cannot be allergic to a hyaluronic acid filler. You may be allergic to what products are added to the filler itself or the process how it is made. Some of the most basic fillers such as Juvederm or Restylane should NOT elicit an allergic reaction. I hope this helps and good luck from New York City plastic surgery
