Short explanatory YouTube segment by Dr. Charles Mok describing hyaluronic acid (hyaluronans) in dermal fillers: filler gel is approximately 98% water and 2% hyaluronans; hyaluronans are hydrophilic and retain water; native hyaluronic acid in the body turns over roughly every 24 hours; manufacturers cross-link hyaluronans to slow breakdown; injection trauma can cause early gel breakdown and may necessitate a touch-up.

These are called hyaluronic acid or hyaluronans. When you buy a syringe of filler, it's 98% water and 2% hyaluronic acid or hyaluronidans. It's not all hyaluronidas, it's only 2%. And that hyaluronans are water loving. We call it hydrophilic. They pull water in so they maintain it there. And your body has hyaluronic acid all over the place, but it turns over every 24 hours. So they've taken these hyaluronins and they've cross linked them. They put little connections between two strands so that they're not susceptible to breakdown. But when you first inject them, your body does react to trauma and breaks a little bit of it down, so you might need a touch up later on.
