Non-Surgical Breast Enlargement
Return to the full category guide.
Thread names are often used loosely in marketing. Understanding the basic types helps. This page is part of our guide to mono threads.
Thread types
How smooth and barbed threads differ
| Feature | Mono (smooth) threads | Cog (barbed) threads |
|---|---|---|
| Design | Smooth filament | Barbs or cones along the thread |
| Intended effect | Skin quality, collagen stimulation | Mechanical lifting or support |
| Placement | Often multiple fine threads in a mesh | Fewer, longer threads anchored in tissue |
| Lifting effect | Minimal | Modest and temporary at best |
| Risks | Bruising, lumps, infection | Same, plus visibility, dimpling, migration |
| Typical use | Skin texture and tone | Facial lifting, some body areas |
Product designs vary. Ask for the exact product name and instructions for use.
Screw or twisted threads
Some threads have a coiled or twisted design intended to add a small amount of volume in the skin. Evidence of lasting volume is limited.
Why it matters in the breast
If a provider offers "threads" for the breast, ask which type, because the intended effect and risk profile differ. Cog threads aim for lift, mono threads aim for skin quality, and neither is designed to add significant volume.
Product labelling
Products can have similar names but different designs. Ask for the product name, manufacturer and instructions for use. Read approved versus off-label use.
Questions to ask
- Which type are you proposing and why?
- What outcome do you expect, and how will we measure it?
- Is this product intended for the breast?
Key takeaway
Know which type of thread is proposed. They are not interchangeable. See breast thread procedures.
