This is because the type of filler affects the results and naturalness of the face. Choosing the right filler will reduce risks and help the results be more beautiful and harmonious.

Thin under-eye filler

Thin under-eye fillers, also known as soft fillers, are ideal for addressing shallow under-eye circles. This is because the filler's molecules are very small, allowing it to disperse well and evenly. Furthermore, the filler's texture is highly flexible, allowing it to rebound well and blend with the skin during facial expressions. This results in a natural, non-lumpy, low-viscosity filler with a more fluid and soft texture than conventional fillers.

Example of a thin under-eye filler

  • Restylane Vital Light The filler has very small molecules, making it ideal for filling in shallow under-eye wrinkles and adding moisture to the skin.
  • Juvederm Volbella The filler is highly flexible and soft, making it ideal for filling in under-eye hollows and addressing fine lines and wrinkles.
  • Belotero Soft The filler has special properties that allow it to blend in with the tissues best, making it ideal for addressing delicate under-eye problems that require smoothness.

Solid under-eye fillers

Solid under-eye fillers, sometimes referred to as dense fillers, are ideal for addressing deep under-eye circles. This is because their large molecules and structure promote firm adhesion, resulting in a dense consistency. They also maintain their shape well, ensuring they stay in place and do not migrate or move from the injection site. They are ideal for filling, supporting, or lifting sagging skin by replacing fat that has collapsed and bone that has eroded with age. Furthermore, solid fillers tend to dissolve more slowly than soft fillers, resulting in longer-lasting results, typically lasting approximately 1–2 years.
