When volume diminishes and contours soften, a subtle process begins – barely noticeable, yet visible. Poly-L-lactic acid (PLLA – Polylactic Acid, also known as Polymilchsäure) helps the skin regain its firmness: not by filling, but by activating the body’s own collagen production. The transformation occurs gradually – with delicate, natural results that develop over several weeks. All without exaggeration. This gentle collagen stimulation promotes lasting skin rejuvenation and a subtle lifting effect that contributes to long-term collagen buildup.
We offer the Polylactic Acid (PLLA) treatment at our clinics in Stuttgart and Baden-Baden – a modern biostimulator-based method for facial rejuvenation and biorevitalization.

BIOSTIMULATION THROUGH COLLAGEN – NATURAL SKIN REJUVENATION INSTEAD OF VOLUME ENHANCEMENT
Collagen is an essential structural protein responsible for the firmness, elasticity, and youthful resilience of the skin. As we age, the body’s natural collagen production slows down – the skin loses volume, wrinkles form, and contours appear less defined. This is where innovative biostimulation with Poly-L-lactic acid (PLLA – Polylactic Acid) comes in: it specifically stimulates new collagen formation and collagen regeneration – without creating immediate volume. Instead, it supports the body’s own regenerative capacity – for gradual, naturally appearing results. This method serves as biorevitalization, wrinkle treatment, and long-lasting skin rejuvenation.
LONG-LASTING EFFECT THROUGH TARGETED COLLAGEN STIMULATION WITH PLLA
The active ingredient Poly-L-lactic acid (PLLA) is injected into the desired skin areas. There, it activates fibroblasts – the cells responsible for collagen synthesis and thus for collagen buildup. The effect does not appear immediately, but unfolds over several weeks: the skin is gradually strengthened, and full results become visible after about three to four months – all without artificial volume or visible foreign substances. PLLA is a well-researched, biodegradable material that has been safely used in medicine for many years – especially for skin rejuvenation, wrinkle treatment, lifting effect, facial rejuvenation, and collagen stimulation.
