#  What is Hyaluronic Acid (HA)?

Hyaluronic Acid is a naturally occurring substance that is already found in your skin. It helps keep skin plump and hydrated. HA fillers are typically soft and gel-like. The results are temporary, lasting 6 to 12 months or longer before the body gradually and naturally absorbs the particles.

Most HA fillers are infused with lidocaine to help minimize discomfort during and after treatment. Popular Brands Include: *Juvéderm and Restylane.* [www.americanboardcosmeticsurgery.org](https://www.americanboardcosmeticsurgery.org)
