What Is the Difference Between PLLA and Fillers?

What is the difference between plla and fillers? This is a common question among patients and practitioners seeking facial rejuvenation solutions. At first glance, they may seem similar since both are injectable treatments designed to restore volume and improve appearance. However, plla products differ significantly from HA dermal fillers in terms of their mechanisms, longevity, and clinical applications, making it essential to understand these distinctions before making a treatment decision.

What Is PLLA?

PLLA, short for poly-L-lactic acid, is a biocompatible and biodegradable synthetic polymer that has been widely used in aesthetic medicine. Unlike conventional dermal fillers that physically add volume beneath the skin, PLLA works by stimulating the body’s own collagen production. Once injected, it gradually activates fibroblasts to rebuild the skin’s structural framework, leading to a more natural and progressive restoration of volume and firmness. Treating face with PLLA allows practitioners to address diffuse volume loss and improve overall skin quality with long-lasting results.

One of the main advantages of PLLA is its longevity. While it may take several weeks or even months for visible improvements to appear, the results are typically more durable than those achieved with traditional fillers, often lasting two years or more. This makes PLLA filler a popular choice for patients seeking gradual, long-term rejuvenation rather than immediate correction.

Among the PLLA products available on the market, Devolux® stands out for its safety, consistency, and effectiveness in promoting collagen regeneration. Trusted by clinics worldwide, it offers a reliable solution for practitioners who aim to deliver natural-looking, long-lasting results to their patients.

What Are Dermal Fillers?

Dermal fillers are injectable substances most commonly made from hyaluronic acid (HA), a molecule naturally present in the skin that plays a vital role in hydration and elasticity. Unlike PLLA, dermal fillers work by physically adding volume to targeted areas, instantly correcting wrinkles, folds, or loss of fullness. This immediate effect makes them highly popular for patients seeking fast and visible improvements.

Fillers are especially versatile in aesthetic treatments. They can be used to enhance facial contours such as the cheeks, chin, or lips, smooth out nasolabial folds, or restore youthful plumpness in areas affected by aging. However, their longevity is generally shorter compared to PLLA, with results lasting around 6 to 18 months depending on the product type, injection technique, and individual metabolism.

Because they provide instant results with minimal downtime, dermal fillers like Revisage ha dermal fillers are often considered the go-to option for patients who want quick aesthetic enhancement without waiting for gradual changes.

Key Differences Between PLLA and Fillers

Aspect	PLLA (Poly-L-lactic Acid)	Dermal Fillers (e.g., HA-based)
Mechanism of Action	Stimulates fibroblasts to produce new collagen, gradually rebuilding skin’s structural framework.	Directly replaces lost volume by injecting a substance (commonly hyaluronic acid) under the skin.
Onset of Results	Results develop progressively over several weeks to months as collagen regeneration takes place.	Provides immediate visible improvement in wrinkles, folds, and volume after injection.
Longevity	Long-lasting effects, typically 2 years or more depending on patient’s metabolism and treatment plan.	Shorter duration, generally 6–18 months before additional sessions are required.
Treatment Goals	Suited for full-face rejuvenation, correction of diffuse volume loss, and long-term improvement in skin quality.	Best for targeted contouring (cheeks, lips, chin) and quick correction of fine lines and folds.
Naturalness of Results	Results appear gradually, blending naturally with the patient’s own collagen over time.	Results are instant and noticeable, which may sometimes look less subtle if overfilled.
Maintenance	Requires fewer retreatments due to longer duration, though multiple initial sessions may be needed for optimal stimulation.	Requires regular maintenance treatments every year or so to sustain desired results.
Patient Preference	Chosen by those seeking gradual, long-term rejuvenation with collagen regeneration.	Preferred by patients who want fast, visible results with minimal waiting.

Expert Perspective: Choosing the Right Option

In summary, the main differences between PLLA and traditional fillers lie in their mechanism of action, speed of results, and duration. Selecting between PLLA and dermal fillers ultimately depends on the patient’s goals, expectations, and treatment timeline. For individuals who want immediate correction—such as enhancing lip volume, contouring the jawline, or smoothing deep folds—dermal fillers are often the most suitable choice because they deliver visible results right after injection.

On the other hand, patients who prioritize long-term rejuvenation and natural collagen regeneration may find PLLA to be the better option. Although results take longer to appear, the gradual improvement often looks more natural and can last significantly longer, making it ideal for addressing generalized volume loss and overall skin quality.

In clinical practice, many professionals also combine both approaches: fillers for instant correction in specific areas, and PLLA for sustained collagen stimulation and global facial rejuvenation. This tailored strategy often provides the best of both worlds.

For those considering PLLA, choosing a reliable and well-researched product is crucial. Solutions like Devolux® have been recognized for their effectiveness in stimulating collagen and delivering natural-looking, long-lasting outcomes, making them a trusted option for clinics and patients alike.
