Difference Between PLLA & PCL Collagen Boosters

In the world of aesthetic treatments, collagen boosters have become a powerful tool for restoring facial volume, reducing wrinkles, and enhancing overall skin health.
Among the most advanced collagen-boosting injectables are PLLA (Poly-L-Lactic Acid) and PCL (Polycaprolactone) products, both known for their collagen-stimulating properties and long-lasting results. But what exactly sets these two types apart, and how should you decide which is best for your clinic’s patients?
In this guide, we’ll explore the key differences between PLLA and PCL collagen boosters, breaking down their composition, longevity, and how they work to deliver beautiful, natural-looking results.

PLLA and PCL Examples: AestheFill and GOURI

To better understand the unique benefits of PLLA and PCL collagen boosters, here’s an introduction to AestheFill and GOURI, two innovative products leading the way in their respective categories:

• AestheFill (PLLA): AestheFill is a next-generation PLLA-based collagen stimulator that gradually improves skin volume and texture by stimulating collagen production in the deeper layers of the skin. Over a series of sessions, AestheFill provides natural, long-lasting results by enhancing facial contours and smoothing out fine lines. The effects of AestheFill can last up to two years, making it a popular choice for patients who seek a subtle, natural transformation with sustained collagen support.

• GOURI (PCL): GOURI is an advanced liquid PCL collagen stimulator designed for an even distribution of collagen stimulation across the treatment area. Its unique formulation requires fewer injection points, offering patients a smooth, natural look with minimal post-procedure shaping. The results of GOURI can last up to four years, giving patients both an immediate volumizing effect and extended collagen production for a youthful, lifted appearance over time.

These two products exemplify the distinctive strengths of PLLA and PCL boosters, providing clinics with flexible options to meet diverse patient needs.

PLLA Collagen Boosters: How Do They Work?

PLLA (Poly-L-Lactic Acid) boosters are bio-stimulatory injectables that work by stimulating the body’s natural collagen production. Unlike traditional fillers, which add immediate volume, PLLA products promote gradual collagen regeneration over time, providing a natural and lasting effect.

• Composition & Action: PLLA is a biodegradable, biocompatible substance that restores the skin’s structure by encouraging collagen growth. This leads to firmer, more youthful skin with improved volume over time.
• Longevity: PLLA products are highly durable, with results typically lasting up to two years or more, making them an ideal choice for patients seeking a long-term solution to volume loss.
• Best Use Cases: PLLA boosters are particularly effective for treating larger areas of the face where significant volume loss has occurred, such as the cheeks, temples, and jawline. They are ideal for patients looking for gradual, natural-looking improvements with minimal downtime.

PCL Collagen Boosters: How Are They Different?

PCL (Polycaprolactone) collagen boosters, like PLLA products, stimulate collagen production but also provide immediate volume due to their unique formulation. PCL products typically contain microspheres in a gel carrier that supports both instant volumization and sustained collagen growth over time.

• Composition & Action: PCL is a soft, semi-crystalline polymer that is biocompatible and biodegradable. It stimulates collagen production like PLLA but also offers an immediate volume boost through its gel carrier. This dual action makes it a popular choice for achieving both instant and long-term results.
• Longevity: PCL products are known for their exceptional longevity, with results that can last three to four years, making them one of the longest-lasting options in collagen boosters.
• Best Use Cases: PCL collagen boosters are well-suited for patients looking for both immediate correction and sustained collagen stimulation. They are effective for facial contouring, treating deep wrinkles, and volumizing areas like the nasolabial folds and marionette lines.

Understanding Collagen Stimulation: The Science Behind PLLA and PCL Boosters

Both PLLA and PCL products work by enhancing the skin’s collagen production, but understanding how this process benefits the skin can help clinics choose the right product for each patient.

Collagen is a protein that provides structure, elasticity, and firmness to the skin. As we age, collagen production decreases, leading to sagging skin, wrinkles, and a loss of volume. PLLA and PCL boosters are designed to counteract this process by encouraging the body to generate more collagen naturally.

• PLLA Boosters activate fibroblasts in the skin, which are the cells responsible for collagen production. Over time, these cells generate new collagen, resulting in gradual and natural improvements in skin structure and volume.
• PCL Boosters not only stimulate collagen production but also provide an immediate lifting effect due to the gel carrier. This means patients can see initial results immediately while benefiting from long-term collagen-stimulating effects.

Patient Expectations and Treatment Customization

When selecting between PLLA and PCL boosters, it’s essential to consider the patient’s preferences and desired outcomes. Some patients may prefer a gradual transformation, while others seek both immediate and long-lasting results. Here’s how to customize treatments based on each product’s unique benefits:

• PLLA: Ideal for patients comfortable with gradual improvement. Since it stimulates collagen over time, results appear subtly, making it a great choice for those desiring natural changes.
• PCL: Better suited for patients who desire immediate results. PCL’s formulation allows for both instant volumization and continued collagen production, offering both short-term and sustained effects.

PLLA vs. PCL: Key Differences to Consider

• Immediate Results vs. Gradual Improvement: PLLA products stimulate collagen gradually, requiring time to show full results. In contrast, PCL boosters offer immediate volume along with long-term collagen support.
• Longevity: Both boosters provide long-lasting results, but PCL products generally last longer. PLLA boosters typically last up to two years, while PCL options can last up to four years.
• Collagen Stimulation: Both products enhance collagen production, but PCL’s immediate volumizing effect may appeal to patients looking for fast results. On the other hand, PLLA offers a more gradual and natural transformation, which some clients prefer.
• Biodegradability: Both PLLA and PCL are biodegradable, meaning they are safely absorbed by the body over time. However, PCL’s slower degradation rate contributes to its extended longevity, making it a preferred choice for clients desiring long-lasting volume.

Frequently Asked Questions (FAQ)

Q: How many sessions are required for PLLA and PCL treatments?
A: PLLA products usually require multiple sessions spaced over a few months for optimal results. PCL boosters can often achieve results in fewer sessions due to their immediate volumizing effect.

Q: Are there any risks associated with these collagen boosters?
A: Minor side effects such as redness, swelling, or bruising may occur with both PLLA and PCL treatments. However, both products are biocompatible and biodegradable, making them safe with minimal risk when administered correctly.

Q: Which areas of the face are best suited for PLLA and PCL collagen boosters?
A: PLLA products are ideal for larger facial areas such as the cheeks and temples, where subtle volume restoration is needed. PCL boosters are better suited for areas requiring more definition and lift, such as the nasolabial folds and marionette lines.
