Collagen Filaments Treatment
A natural boost for sagging
or tired-looking skin.

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.

Bio-Stimulator for Stronger, Smoother Skin

  • Restores collagen – Strengthens the foundation of ageing skin.

  • Tightens crepey areas – Ideal for face, neck, or lower cheeks.

  • Enhances skin density – Promotes a fuller, refreshed appearance.

  • No downtime, natural results – Doctor-led treatment with visible long-term benefits.

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.

What to Expect During, Your Collgen Filaments Treatment

Collagen Filament Insertion
Tiny micro-channels are gently created using a medical-grade device. This opens the skin to receive the Rejuran formula and stimulates natural collagen production.

Stimulation & Regeneration
Purified salmon DNA  is delivered intothe skin to help restore texture, firmness, and glow. It’s gently worked into the skin where ealing and regeneration are needed most.

Results & Longevity
You may notice slight redness for 24–48 hours. Then, your skin starts to feel smoother, more hydrated, and visibly healthier—with results that build over time.

Why hair loss happens for women

For women  - Lift, Smooth & Restore

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.

Why hair loss happens for men

For men - Strengthen & Define

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.

Frequently asked Questions.

What is a Collagen Filament Treatment?

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.

How does collagen filament treatment work beneath the skin?

  • Filaments are gently inserted just under the surface in targeted areas.
  • They act as a scaffold, stimulating fibroblasts — the cells responsible for collagen production.
  • Over time, the filaments dissolve naturally, leaving behind newly generated collagen that continues to strengthen and firm the skin.

What is PLACL, and why is it used in Collagen Filaments?

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.

How soon will I see results from collagen filament treatment?

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.

Is there any downtime after a collagen filament treatment?

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.

How does collagen loss affect my skin as I age?

With age, your body produces 1–1.5% less collagen every year. This leads to:

  • Fine lines and wrinkles
  • Thinner, crepey texture
  • Sagging skin and loss of elasticity

Collagen Filaments help reverse this gradual decline by activating the skin’s regenerative response.

How long does the collagen filament procedure take?

Treatment typically takes 10–15 minutes — a quick, in-clinic procedure performed by our doctor-led team.
