what's biphasic filler and monophasic filler

1. What is a Biphasic Filler?

A biphasic filler consists of two components:

• Cross-linked hyaluronic acid particles

• Non-cross-linked 

 These components are mixed together, forming a structure in which solid HA particles are suspended within a gel matrix.

Key Characteristics:

1. Visible particle structure: Distinct particles can be observed under a microscope

2. Strong lifting and supporting capacity: Suitable for areas requiring structural support

3. Lower cohesiveness and flexibility compared to monophasic fillers

4. Relatively longer duration, depending on cross-linking degree and individual metabolism

Common theoretical application areas:
The nose, chin, and jawline—regions that require firm support and clear contour definition.

2. What is a Monophasic Filler?

A monophasic filler is produced through a specific manufacturing process that transforms cross-linked hyaluronic acid into a homogeneous, continuous gel without visible particles.

Key Characteristics:

1. Smooth and uniform texture with no particle sensation

2. High cohesiveness and spreadability, allowing better tissue integration

3. Soft and natural feel after injection

4. Well-suited for superficial layers and dynamic facial areas

Common theoretical application areas:
The lips, tear troughs, nasolabial folds, and fine facial lines where natural movement and smooth transitions are desired.

3. Key Differences Between Monophasic and Biphasic Fillers

4. How to Choose the Appropriate Filler Type

Neither filler type is universally superior. The selection depends on multiple factors, including:

• Individual facial anatomy

• Injection depth

• Aesthetic goals

• Specific product characteristics

5. Conclusion

Both monophasic and biphasic fillers have distinct advantages:

• Monophasic fillers offer superior softness, natural appearance, and tissue integration

• Biphasic fillers provide stronger structural support and contouring capability
