Ruby No.5 Mono Threads: The Skin Firming Treatment That's Not a Lift — VERZO CLINIC Bangkok

TL;DR: Ruby No.5 mono threads are smooth, unbarbed PDO threads designed for skin firming and collagen stimulation rather than mechanical lifting. They are inserted in a mesh-like pattern across the face (typically 20-50 threads per session) to create a scaffold that triggers widespread collagen production, improving skin texture and firmness over 2-4 months.

Frequently Asked Questions

What are Ruby No.5 mono threads?

Ruby No.5 mono threads are smooth, unbarbed PDO threads designed for skin firming and collagen stimulation rather than mechanical lifting. They are inserted in a mesh-like pattern across the face (typically 20-50 threads per session) to create a scaffold that triggers widespread collagen production, improving skin texture and firmness over 2-4 months.

What is the difference between mono threads and cog threads?

Mono threads are smooth threads without barbs — they firm and tighten skin through collagen stimulation. Cog threads have barbs or hooks that grab tissue and physically lift it upward. Mono threads are for skin quality improvement, while cog threads are for visible lifting of sagging tissue. They serve complementary purposes and are often used together.

How many Ruby No.5 threads are used per treatment?

A typical Ruby No.5 treatment uses 20 to 50 threads per session depending on the treatment area and desired effect. Full-face stimulation usually requires 30-50 threads. Targeted areas like the forehead or neck may use 20-30 threads. The threads are placed in a cross-hatch pattern for maximum collagen stimulation.

Does a Ruby No.5 treatment hurt?

Ruby No.5 mono thread insertion is generally less painful than cog thread procedures because the threads are thinner and do not have barbs. Local anesthetic cream and small injection points are used. Most patients describe the sensation as a mild prickling or pressure. The procedure takes 30-45 minutes.

How long do Ruby No.5 results last?

The PDO threads dissolve over 6-8 months, but the collagen they stimulate continues to support skin firmness for 12-18 months after treatment. Most patients notice improvement starting at 2-4 weeks, with peak results at 2-3 months. Annual maintenance sessions can keep results ongoing.

How much does Ruby No.5 treatment cost in Bangkok?

At VERZO CLINIC, Ruby No.5 mono thread treatment averages approximately 71,000 THB depending on the number of threads used. This includes the consultation, procedure, and follow-up. Pricing is approximately 40-50% less than equivalent procedures in Japan or South Korea.

Who is the ideal candidate for Ruby No.5 mono threads?

Ideal candidates are those in their 30s-50s who notice early skin laxity, fine lines, or loss of skin firmness but do not yet need significant lifting. Ruby No.5 is also excellent as a maintenance treatment between cog thread sessions or as a complement to device treatments like Ulthera or Thermage.

What areas can be treated with Ruby No.5 mono threads?

Ruby No.5 threads can be placed across the full face, forehead, under-eye area, cheeks, jawline, and neck. The neck is a particularly popular treatment area because mono threads work well on thinner skin where cog threads may be too aggressive.
