All hyaluronic acid fillers do the same basic job, but the manufacturing process behind each brand changes how it behaves once injected.
All products here are hyaluronic acid (HA), a naturally occurring sugar molecule cross-linked to last longer in the skin. Every brand FDA-regulates as a Class III medical device and every one is reversible with the enzyme hyaluronidase if a correction is needed. What differs is the cross-linking method, gel firmness, and concentration, which changes where each product performs best.
