How dermal fillers work
What dermal fillers are made of, how they work, where they’re used and what to expect from treatment.
What are dermal fillers?
Dermal fillers are injectable gels made from hyaluronic acid (HA), a substance found naturally in the skin that provides volume and hydration. They’re used to restore lost volume, smooth wrinkles and define facial contours.
How they work
Hyaluronic acid attracts and holds water, so filler adds volume and hydration straight away. Once injected, it integrates with the surrounding tissue and gives it structure and support.
Where fillers are used
- Lips: to add volume and shape
- Cheeks: to restore definition to the cheekbones
- Nasolabial folds: to soften smile lines
- Jawline: to define and contour the jaw
What to expect
Treatment typically takes 30–45 minutes, and you’ll see the result straight away. Most fillers last 6–18 months, depending on the area treated and the product used. You may have some minor swelling or bruising, which usually settles within a few days.
