💉 Thread Lift Skin Tightening Mechanism Simulator

Baseline Sagging — Lower Face and Jowl Laxity

Age-related soft tissue descent creates jowls and laxity.

• 35–60: Typical patient age (placeholder range)
• Jowl / jawline: Primary target zone (placeholder)
• ~1%: Collagen decline/decade (placeholder)
• Mild–Mod: Candidate laxity grade (placeholder)

Why tissue sags

Collagen and elastin decline gradually with age.

Assessment approach

Vector mapping plans thread placement before insertion.

Cannula-Guided Subdermal Thread Placement

A fine cannula threads the barbed suture beneath the skin.

• PDO: Thread material (polydioxanone)
• Subdermal: Insertion depth (placeholder)
• ~19–21G: Needle/cannula gauge (placeholder)
• ~30 min: Procedure time (placeholder)

Insertion technique

Thread follows a planned vector toward the anchor zone.

Barb orientation

Cogs face backward to resist tissue slippage.

Barb Anchoring and Immediate Mechanical Lift

Barbs grip tissue; gentle tension lifts the sagging contour.

• Moderate: Immediate lift range (placeholder)
• Multiple barbs: Anchor points/thread (placeholder)
• Immediate: Effect visibility (placeholder)
• 2–8: Threads per side (placeholder)

Tensioning mechanics

Cogs lock into tissue as excess thread is trimmed.

Vector planning

Multiple threads distribute lift across the jawline.

PDO Absorption and Foreign-Body Collagen Response

Thread dissolves over months while stimulating new collagen.

• ~6 months: Full PDO absorption (placeholder)
• ~1–2 months: Collagen onset (placeholder)
• ~6–9 months: Peak collagen build (placeholder)
• Foreign-body: Response type (placeholder)

Dissolution timeline

Hydrolysis breaks the thread down gradually and safely.

Collagen handoff

New collagen forms along the track as thread fades.

Durable Lift From Mechanical-to-Collagen Handoff

Collagen support sustains tightening after thread dissolves.

• 12–18 mo: Effect duration (placeholder)
• 0%: Thread remaining at 18mo (placeholder)
• High: Collagen at 18mo (placeholder)
• ~12–18 mo: Retreatment interval (placeholder)

Sustained tightening

New collagen matrix maintains contour after full absorption.

Retreatment planning

Effect fades gradually; repeat threading restores lift.
