What Are Dermal Fillers?

Dermal fillers are sterile gels used to plump up areas of the skin, making them look fuller and firmer.

Hyaluronic acid fillers such as Restylane® are the most commonly used fillers today. Hyaluronic acid is found naturally in the skin, joints and eyes. It is a precursor to collagen and is a natural and very effective humectant (water holding molecule). This helps to keep the skin supple and hydrated, and gives the skin volume. Over time the hyaluronic acid is broken down in the body.

The hyaluronic acid in fillers is cross-linked to slow down the natural absorption process. This gives these fillers a longevity of six to twelve months.
