What is collagen-stimulating injection?
Collagen-stimulating injection is an injectable collagen stimulator containing poly-L-lactic acid (PLLA) — a biocompatible, biodegradable synthetic polymer. Unlike hyaluronic acid fillers that provide immediate volume, The product works by stimulating your skin's fibroblasts to produce new collagen over time.
The result is a gradual, natural improvement in facial volume and contour that looks completely natural — because it is. Your own collagen is doing the work.
What does it treat?
- Hollowing of the temples and mid-face
- Cheek volume loss and flattening
- Deep smile lines (nasolabial folds)
- Jaw and chin contouring
- Overall facial skeletal support and structure
- Body: buttocks augmentation (non-surgical BBL)
Results & Longevity
Results are not immediate — the collagen builds gradually over 3–6 months. Most patients need 2–3 sessions spaced 4–8 weeks apart for full effect. The investment pays off: results typically last 2 or more years, significantly longer than standard HA fillers.
Is this a filler? +
Collagen-stimulating injection is often categorised with fillers but is fundamentally different. Standard HA fillers add volume immediately through the filler material itself. PLLA-based collagen biostimulators work by stimulating your own collagen — they are biostimulators, not fillers. The volume comes from your own tissue.
When will I see results? +
Initial results become visible at 4–8 weeks after the first session, as new collagen begins to form. Full results develop over 3–6 months after the last session. Patience is rewarded with natural, lasting results.
How long does the treatment last? +
Clinical studies of PLLA-based collagen biostimulators show results that can last 25+ months in many patients. Annual maintenance sessions are typically discussed to sustain results.
