PLLA (poly‑L‑lactic acid) is a collagen‑stimulating injectable that works gradually—helping your skin rebuild strength and support over time rather than giving an instant, “filled” look. It’s a strong choice when you want a more structural, long‑term boost in firmness and skin resilience, with results that develop progressively over weeks to months as new collagen forms.

If you’ve tried regenerative injectables before, the feel of the result is often different: polynucleotides are typically positioned more as a skin‑quality “repair and hydration” approach, whereas PLLA is used when you want deeper collagen stimulation and longer‑range reinforcement of the skin’s framework.

At Dr Alluris Aesthetics, PLLA is planned in a doctor‑led, anatomy‑first way so the improvement stays natural, balanced, and consistent with how you move and express.
