Everything You Need to Know About Mono Threads

Collagen is what keeps our skin firm, smooth, and youthful. Starting in our mid-20s, we naturally lose about 1% of it each year. Over time, that gradual loss leads to fine lines, wrinkles, sagging, and changes in skin texture. That’s why stimulating collagen is important for maintaining healthy skin and slowing the visible signs of aging.

Mono threads are a minimally invasive way to do exactly that. They stimulate your body to produce new collagen, which helps tighten the skin, improve crepey areas, boost elasticity, and enhance overall skin quality.

What Are Mono Threads?

Mono threads are smooth, dissolvable sutures placed just under the skin. Unlike lifting threads that reposition the tissue, mono threads act more like a collagen booster. As the threads dissolve, your body produces fresh collagen around them, which gradually improves skin texture and firmness. Some patients notice improvement right away, while results continue to build and look even better over the course of a few weeks.

Where Can Mono Threads Be Used?

Mono threads are versatile and safe to use on both the face and body. Popular treatment areas include:

• Fine lines under the eyes
• Accordion lines on the cheeks
• Wrinkles around the mouth
• Crepey skin on the neck and chest
• Laxity under the chin
• Loose skin on areas like the abdomen, arms, or knees

Because they don’t add volume, they’re useful in areas where filler may not be the best option.

The Different Types of Mono Threads

There are several thread materials available, each with unique benefits:

PDO Threads

PDO (polydioxanone) threads are the most common. PDO threads have great safety profile, it has been used in cardiac surgery for the last 20 years before introduction to aesthetic medicine. They last about 6 months before dissolving, with results from collagen stimulation continuing for 12 to 18 months.

PCL Threads

PCL (polycaprolactone) threads dissolve more slowly, usually lasting 12 to 18 months. Collagen stimulation is more robust then PDO threads.

PLLA Threads

PLLA (poly-L-lactic acid) threads are known for their strong collagen stimulation and longer-lasting results, often up to 24 months. This is the same material used in Sculptra, making them ideal for patients who need extended improvement in skin quality.

Potential Complications

As with any aesthetic procedure, PLLA threads come with certain risks. While most patients tolerate the treatment well, some possible complications include:

• Bruising – Temporary bruising at the insertion site is common and usually resolves within a few days.

• Thread migration – In rare cases, threads may shift slightly from their original placement, which can cause unevenness or small irregularities.

Why Choose Mono Threads?

Patients often choose mono threads when they want:

• A natural, refreshed look without adding volume

• Avoid intravascular injection, one of the most serious complications from fillers injection.
