Dermal Filler

Science behind crosslinking

In aesthetic medicine, not all fillers are created equal — not even hyaluronic acid–based ones.

HA – hyaluronic acid – is a molecule naturally found in the skin. Its production decreases over time, contributing to loss of firmness and the appearance of wrinkles. Hyaluronic acid plays a central role in dermal fillers, but its cross-linked forms are the foundation of the Bonitto product line.

That’s why all Bonitto fillers are cross-linked.

What is crosslinking?

Crosslinking is a chemical process that connects hyaluronic acid molecules, creating a stable, three-dimensional network.

This structure allows the filler to maintain shape and performance for 6 to 18 months, depending on the formulation and treatment area.

From denser fillers for deep structural support to softer ones for lips and fine lines, Bonitto fillers use different degrees of cross-linking to meet specific needs:

• High density – Structural volumization
• Medium density – Moderate wrinkle correction, contour definition
• Low density – Lips, superficial lines, deep hydration

Our philosophy and method

When planning a filler treatment, a qualified professional always considers individual facial anatomy, specific aesthetic goals, skin texture and dermal thickness, previous treatments, patient expectations.

And there are four further principles that play a crucial role in the world of cross-linked fillers:

• Surgical Precision
  The stable structure of cross-linked HA allows for millimetric control in sculpting andreshaping, ensuring defined, symmetrical and predictable results over time.
• Proven Safety
  Decades of clinical research and millions of documented treatments confirm the high safety profile of premium cross-linked fillers, now considered a reliable standard in aesthetic medicine.
• Natural Results
  New-generation formulations provide softness, optimal tissue integration and natural movement, eliminating the “frozen effect” associated with less advanced products and techniques.
• Reversibility
  If necessary, hyaluronic acid fillers can be fully dissolved using hyaluronidase, offering an additional layer of safety, control and personalization of the treatment.
