How much PMMA is in Bellafill?

Published in Dermal Filler Composition 2 mins read

Bellafill contains 20% PMMA microspheres. This percentage refers to the poly(methyl methacrylate) component within the dermal filler.

Understanding Bellafill's Composition

Bellafill is a unique dermal filler known for its long-lasting results, primarily due to its distinct composition. It is formulated to provide immediate volume and stimulate the body's natural collagen production over time.

The primary components of Bellafill include:

  • Poly(methyl methacrylate) (PMMA) microspheres: These are small, non-absorbable synthetic spheres that provide structural support.
  • Bovine collagen gel: This is the immediate filler component that provides volume upon injection.
  • Lidocaine: An anesthetic that helps reduce discomfort during the injection process.

Breakdown of Bellafill Components

The precise formulation ensures that each component contributes to the filler's overall effectiveness and longevity.

Component Percentage Description
PMMA Microspheres 20% Non-resorbable spheres, approximately 6 million per syringe, stimulating collagen.
Bovine Collagen Gel 80% Provides immediate volume and scaffolding for new collagen.
Lidocaine 0.3% A local anesthetic included to enhance patient comfort during the procedure.

The Role of PMMA Microspheres

The PMMA microspheres are a critical component of Bellafill, differentiating it from temporary dermal fillers. These microspheres are carefully manufactured to ensure their safety and efficacy within the body.

Key characteristics of the PMMA microspheres in Bellafill include:

  • Size: They typically range from 30 to 50 microns, which is an optimal size for remaining in place while minimizing the risk of migration.
  • Shape and Uniformity: The production process yields microspheres that are round, smooth, and relatively uniform. This design promotes safety and reduces the likelihood of adverse reactions.
  • Collagen Stimulation: Once injected, these microspheres are encased by the body's natural collagen, which progressively forms around each sphere. This new collagen provides a lasting scaffold, leading to sustained correction of wrinkles and volume loss.

Unlike hyaluronic acid fillers that are eventually absorbed by the body, the PMMA microspheres remain, offering a long-term solution for dermal augmentation.
