How Long Cog Threads Differ from Smooth Threads
Thread treatments are medical procedures that may assist with tissue support and collagen stimulation in suitable patients following clinical assessment. Different thread types are used depending on the individual’s anatomy, concerns, and treatment goals.
Two commonly used types are long cog threads and smooth threads. While both are absorbable and designed to support skin quality, they serve different purposes.
What Are Smooth Threads?
Smooth threads are fine, absorbable sutures placed beneath the skin to support collagen stimulation.
They may assist with:
• improving skin quality and firmness
• supporting collagen production
• enhancing overall skin texture
• addressing early skin laxity
Smooth threads do not provide structural lifting. Instead, they are often used to improve skin quality and support subtle rejuvenation.
What Are Long Cog Threads?
Long cog threads are absorbable threads designed with tiny barbs (“cogs”) that gently engage with tissue once placed.
They may assist with:
• supporting areas affected by skin laxity
• enhancing facial contours
• providing structural support in suitable patients
• stimulating collagen over time
Because of their design, cog threads are used when additional structural support is clinically appropriate.
Purpose
Smooth threads: collagen stimulation and skin quality
Cog threads: structural support and contour support
Lifting Effect
Smooth threads: no lifting effect
Cog threads: may assist with tissue support in suitable patients
Treatment Goals
Smooth threads: skin rejuvenation and firmness
Cog threads: support for sagging or loss of structural definition
Which Thread Type Is Right for You?
Thread treatments are not one-size-fits-all. A qualified medical professional will assess your facial structure, skin quality, and treatment goals to determine suitability and discuss appropriate options.
Not everyone is suitable for thread treatments. Outcomes vary between individuals, and potential risks and recovery considerations are discussed during consultation.
