💉 What Is PLLA in Cosmetics?
PLLA (Poly-L-Lactic Acid) is a biostimulatory injectable used to restore volume and rejuvenate the skin.
It’s the active ingredient in well-known products like Sculptra®, Derma Veil®, and AestheFill®.

⚙️ How It Works
Unlike traditional fillers (like hyaluronic acid), PLLA doesn’t add instant volume.
Instead, it:
1. Triggers fibroblasts in your skin to produce new collagen.
2. The microparticles of PLLA gradually break down into lactic acid, a natural body substance.
3. Over several months, your skin thickens, firms, and gains elasticity as collagen builds up.
So you’re not getting volume from the filler itself — you’re getting it from your own collagen 💪

🕒 Treatment Timeline
• Number of sessions: Usually 2–3 sessions, spaced 4–6 weeks apart.
• Visible results: Often appear after 8–12 weeks, once collagen starts forming.
• Longevity: Results typically last up to 2 years, sometimes longer with maintenance.
