Poly-L-Lactic Acid (PLLA)

What Is Poly-L-Lactic Acid (PLLA)?

Poly-L-lactic acid (PLLA) is a biocompatible and biodegradable biostimulator molecule.
When placed beneath the skin, rather than adding volume directly, it aims to stimulate the body’s own collagen production.

Products containing PLLA have long been used in aesthetic and regenerative medicine as part of collagen-stimulation approaches.

How Does PLLA Work?

After it is placed beneath the skin, PLLA is slowly metabolised over time.
During this process:

• Fibroblast activity is stimulated
• New collagen synthesis is triggered
• Tissue support gradually increases

The effect of PLLA is not immediate; it is a gradual, biological process. As collagen production increases, the aim is to achieve:

• Firmer skin structure
• Fuller, better-supported tissue
• A more even surface appearance

What Makes the PLLA Result Distinctive

The goal of PLLA treatment is not to create volume at the moment of treatment.
The change achieved:

• Develops over time
• Relies on the skin’s own collagen structure
• Does not create overfilling or an artificial look

This is why PLLA is a frequently chosen biostimulator for people who expect a natural result.

Where Is Poly-L-Lactic Acid (PLLA) Used?

PLLA biostimulators can be used on both the face and the body. The areas most often assessed are:

• Face (cheeks, mid-face and lower-face support areas)
• Temples
• Neck
• Décolletage

In some cases it may also be used on body areas to support tissue quality.

How Is a PLLA Treatment Planned?

• Skin structure and tissue needs are assessed
• The degree of collagen loss is analysed
• Treatment areas are determined individually
• The treatment is usually performed with a cannula

PLLA can be applied in a single session or, depending on the skin’s needs, as sessions planned at set intervals.

When Do Results Appear?

The effect of PLLA usually appears gradually:

• A slight sense of fullness in the first weeks
• Collagen synthesis begins within 4–6 weeks
• Improvement in tissue quality becomes visible within 2–3 months

Who Might It Suit?

After a medical assessment, PLLA may be planned for people who:

• Have lost volume and support in the skin
• Are concerned about sagging and laxity
• Want a natural effect that develops over time
• Do not want a classic filler treatment

Natural Appearance and Patient Safety

The core approach of PLLA treatment is to support collagen production while respecting the skin’s biological structure.
The entire assessment and treatment process is carried out with facial and body anatomy in mind and with patient safety as the priority.
