As we age, our skin naturally produces less collagen — about 1 to 1.5% less each year — leading to fine lines, wrinkles, and a loss of firmness. Sisu Clinic’s new Collagen Filaments Treatment helps reverse this process by stimulating your skin’s own collagen and elastin production. Using advanced bio-stimulating technology, this treatment supports gradual skin renewal for firmer, smoother, and more radiant skin — with no downtime and long-lasting results.

If you’ve noticed your skin starting to lose its bounce or look a little crepey, it’s often because collagen production has slowed — something that happens naturally with age. The Collagen Filament Treatment uses PLACL, a unique bio-stimulating material, to gently activate your skin’s own collagen and elastin renewal. Inserted just beneath the surface, the filaments encourage gradual regeneration, helping restore firmness and density while smoothing fine lines and wrinkles. Over the following months, skin becomes tighter, brighter, and more resilient — naturally.

Results That Speak for Themselves




Grounded in regenerative science, Collagen Filament Treatment works with your body’s natural healing process to rebuild structure and elasticity from within.The unique PLACL biostimulatory material encourages collagen renewal over time, improving skin density and texture.This gentle, non-surgical treatment restores the skin’s support system — leaving it firmer, stronger, and more radiant for months to come.


Women often notice collagen loss first through fine lines, sagging, or that thin, crepey texture on the face and neck. Collagen Filament Treatment helps restore firmness and elasticity, rebuilding the skin’s natural structure from within.

Men experience gradual collagen loss too, often leading to looser skin along the jawline, dullness, or visible fatigue. This treatment offers a simple, no-downtime way to tighten and strengthen skin from the inside — restoring a firm, defined look that still feels completely natural.
Results That Speak for Themselves



Collagen Filament Treatment is a bio-stimulating skin rejuvenation procedure that uses fine, absorbable filaments made from PLACL (a collagen-stimulating material). These filaments trigger your skin’s natural regeneration process — boosting collagen, elastin, and hyaluronic acid for firmer, smoother, more radiant skin.
PLACL (poly-L-lactide-co-caprolactone) is a bio-absorbable material that gradually dissolves while stimulating natural collagen, elastin, and hyaluronic acid production. It’s safe, clinically tested, and designed for long-lasting regenerative effects.
Results develop gradually over 3–6 months as collagen rebuilds. You’ll first notice improved texture and firmness, followed by smoother, more resilient skin that can last up to 18 months.
There’s no downtime — you can return to your day immediately after. Mild redness or tenderness may occur for a few hours, but it settles quickly.
With age, your body produces 1–1.5% less collagen every year. This leads to:
Collagen Filaments help reverse this gradual decline by activating the skin’s regenerative response.
Treatment typically takes 10–15 minutes — a quick, in-clinic procedure performed by our doctor-led team.
