Discover how dermal fillers work, different types available, and what to expect from your treatment journey.

What Are Dermal Fillers?

Dermal fillers are injectable gels made from hyaluronic acid (HA), a naturally occurring substance in the skin that provides volume and hydration. They are used to restore lost volume, smooth wrinkles, and enhance facial contours.

How Do Fillers Work?

Hyaluronic acid fillers work by attracting and holding water molecules, providing immediate volume and hydration. When injected into the skin, they integrate with the natural tissue, providing structure and support.

Types of Dermal Fillers

  • Lip Fillers: Enhance lip volume and shape
  • Cheek Fillers: Restore cheekbone definition
  • Nasolabial Fillers: Smooth smile lines
  • Jawline Fillers: Define and contour the jaw

What to Expect

Treatment typically takes 30-45 minutes with immediate results. Most fillers last 6-18 months depending on the area treated and the product used. Minor swelling and bruising may occur but usually resolves within a few days.
