What are dermal fillers?

Dermal fillers are small injections of gel, typically made up of hylauronic acid, that fill in wrinkles and add volume to soft tissue. You can have dermal fillers in different parts of your face: around your eyes, cheeks, mouth and jawline, as well as lip fillers administered directly into the lip tissue.

How do they work?
Fillers basically restore lost volume to your face and plump areas, so that deep set lines are smoothed. Why is this needed? Well, as we get older our bodies stop producing collagen and elastin, both of which contribute to the youthful look. Experts argue over when we start losing collagen; but the generally agreed age is 25. Which is pretty young, right? Your collagen and elastin levels then decline at a rate of about 2% per year, and your body will have stopped producing it altogether by your late twenties.
