PLLA Threads

What Are Auro PLLA Threads?

Auro PLLA Threads are collagen-stimulating absorbable aesthetic threads made from poly-L-lactic acid (PLLA). Often known as baby face threads in some Asian aesthetic markets, PLLA Threads are designed to support gradual skin rejuvenation through collagen stimulation rather than relying only on mechanical lifting.

Unlike traditional lifting-focused threads, PLLA Threads focus on improving skin quality, firmness, and tissue structure through a progressive collagen remodeling process.

Auro PLLA Threads provide professional solutions for practitioners seeking collagen-focused thread treatments for facial rejuvenation and aesthetic enhancement.

Why Are PLLA Threads Called Collagen-Stimulating Threads?

PLLA Threads are widely recognized for their collagen biostimulation characteristics.

After placement, PLLA interacts with surrounding tissue and stimulates a gradual regenerative response. This process encourages collagen production around the treated area, helping support improvements in skin firmness and texture over time.

The key value of PLLA Threads is not only lifting support, but also supporting long-term skin rejuvenation through collagen remodeling.

PLLA Threads vs PDO Threads: Which One Should Practitioners Choose?

PLLA and PDO Threads are both absorbable aesthetic threads, but they serve different treatment philosophies.

PLLA Threads

• Material: Poly-L-lactic Acid
• Main Focus: Collagen biostimulation
• Treatment Approach: Gradual rejuvenation
• Typical Positioning: Baby face collagen thread

PDO Threads

• Material: Polydioxanone
• Main Focus: Lifting support and collagen stimulation
• Treatment Approach: Structural support and tightening
• Typical Positioning: Traditional lifting thread

Practitioners may choose PLLA Threads when collagen stimulation and skin rejuvenation are the primary goals, while PDO Threads may be preferred for versatile lifting and tightening applications.

PLLA Threads vs PCL Threads: What Is the Difference?

PLLA (Poly-L-lactic Acid) and PCL (Polycaprolactone) are both biodegradable materials used in advanced aesthetic thread applications. Although both materials can stimulate collagen remodeling, they have different material characteristics and are selected according to different treatment approaches.

PLLA Threads

• Material: Poly-L-lactic Acid (PLLA)
• Primary Focus: Collagen biostimulation and tissue rejuvenation
• Biological Response: Designed to stimulate collagen formation through gradual tissue response
• Treatment Philosophy: Skin quality improvement and gradual rejuvenation
• Common Positioning: Collagen stimulation or baby face thread

PCL Threads

• Material: Polycaprolactone (PCL)
• Primary Focus: Extended collagen remodeling and material performance
• Biological Response: Designed to provide a slower degradation profile and prolonged interaction with tissue
• Treatment Philosophy: Long-term support and collagen remodeling
• Common Positioning: Advanced absorbable thread material

How Do Practitioners Choose Between PLLA and PCL Threads?

The choice between PLLA and PCL Threads depends on the desired treatment objective and material preference.

PLLA Threads may be preferred when the main goal is:

• Collagen biostimulation
• Improving skin firmness and texture
• Gradual facial rejuvenation
• Supporting a regenerative aesthetic approach

PCL Threads may be preferred when the main goal is:

• A slower degradation profile
• Longer interaction with surrounding tissue
• Extended collagen remodeling
• Long-term tissue support applications

Both PLLA and PCL Threads provide collagen-related benefits, but they represent different approaches to absorbable thread treatments.

What Are PLLA Threads Used For?

PLLA Threads are commonly used for:

• Facial rejuvenation
• Skin firmness improvement
• Fine skin texture enhancement
• Facial contour support
• Early signs of skin laxity

PLLA Threads are often selected for patients seeking a gradual improvement in overall skin quality rather than only immediate lifting.

How Do PLLA Threads Work?

PLLA Threads work through collagen biostimulation.

After insertion, PLLA material gradually stimulates tissue response and collagen production around the treatment area. As collagen remodeling occurs, the skin structure may become more supported and improved over time.

The gradual mechanism is one of the key differences between PLLA Threads and purely mechanical lifting approaches.
