L-Proline & Glycine: Scientific Innovation in BDDE-Crosslinked Hyaluronic Acid Fillers

 

At Bonitto, we believe that an aesthetic filler should do more than restore volume—it should actively improve the skin’s biological foundation. Our formulation unites BDDE-crosslinked Hyaluronic Acid with L-Proline and Glycine, two essential amino acids fundamental to collagen formation and dermal regeneration.
This advanced synergy delivers immediate shaping with progressive skin rejuvenation, ensuring results that are natural, durable, and clinically meaningful.

A Next-Generation Matrix: Stability, Structure & Performance

 

Bonitto fillers are manufactured using BDDE cross-linking technology, forming stable ether bonds known for their low toxicity and long-term durability. This reaction creates a three-dimensional “spiderweb-like” HA matrix, a structural hallmark of high-quality, cross-linked hydrogels.

Scientifically, this matrix exhibits:

  • Solid-like elastic behavior (G’ > G”) across relevant frequencies
  • Low tan δ values, reflecting strong structural integrity
  • Stable viscoelastic performance across body-temperature ranges

These rheological properties translate to real clinical benefits:
predictable lifting, shape retention, and harmonious integration into facial tissue.

Amino Acid Enrichment: The Biology Behind Beautiful Skin

 

While the HA-BDDE network provides mechanical stability, the addition of L-Proline and Glycine introduces a powerful biological advantage.

1. Collagen Stimulation

As the primary building blocks of collagen, these amino acids support fibroblast activity and encourage new collagen synthesis around the implanted filler. This enhances firmness and improves dermal density over time.

2. Enhanced Tissue Integration

The optimized ECM environment promotes smoother blending between the filler and surrounding tissues, reducing the risk of irregularities and providing a more natural touch and appearance.

3. Long-Term Reinforcement

By supporting ECM regeneration, L-Proline and Glycine help maintain volumizing effects for longer, complementing the chemical longevity of BDDE ether bonds.

4. Skin Recovery & Comfort

These amino acids participate in wound-healing pathways and modulate micro-inflammation, promoting a gentler injection experience and improved post-treatment comfort.

Dual-Action Technology for Superior Outcomes

 

Bonitto fillers combine two powerful mechanisms:

Structural Action (BDDE Crosslinking)

  • High stability and elasticity
  • Long-lasting volumizing effect
  • Strong resistance to deformation
  • Predictable performance in dynamic facial areas

Biological Action (L-Proline + Glycine)

  • Support of collagen type I & III synthesis
  • Improvement in skin elasticity and firmness
  • Reinforcement of dermal architecture
  • Progressive enhancement in skin quality

The result: A filler that not only shapes but actively rejuvenates.

Why Practitioners Choose Bonitto

 

  • Natural texture & seamless integration thanks to stable G’/G’’ balance
  • Immediate lifting with ongoing tissue renewal
  • Reliable longevity through BDDE-ether stability + ECM support
  • Optimal comfort and recovery driven by amino-acid bioactivity
