Why Everyone Is Talking About “Liquid Threads”

A few years ago, if you wanted real lifting results, your options were limited: either go for fillers (instant but sometimes unnatural), or thread lifts (effective but invasive).

Today, there’s a new category changing everything:

Liquid threads — also known as Ultracol.

This treatment sits right in the middle of modern aesthetics:

Natural-looking

Regenerative

Minimally invasive

Long-lasting

And most importantly, it doesn’t just “fix” the skin.

It rebuilds it from within.

What Are Liquid Threads (Ultracol)?

Liquid threads (Ultracol) are an advanced injectable collagen stimulator made from PDO (polydioxanone)—a material widely used in medical sutures for decades due to its safety and biocompatibility.

Instead of inserting solid threads under the skin, Ultracol transforms PDO into microspheres (liquid form) that can be injected precisely into targeted areas.

Once injected, it works as a biostimulator, meaning:

It does not create instant artificial volume
It triggers your body to produce new collagen naturally

Think of it as a liquid version of a thread lift without threads.

How Liquid Threads Work (The Science Behind It)

After injection, PDO microspheres activate a natural healing response in the skin.

Here’s what happens:

Collagen stimulation begins (Type I and III collagen)
Skin becomes thicker, firmer, and more elastic
Fine lines and wrinkles gradually soften
A natural lifting effect appears over time

Unlike fillers, which simply add volume, Ultracol works by improving skin structure itself.

PDO is biodegradable and safely absorbed by the body within months, leaving behind only regenerated, healthier skin.

Ultracol is formulated using advanced micro-processed PDO technology, where polydioxanone is refined into ultra-fine microspheres for smooth, precise injection into the skin. This allows for even distribution and controlled collagen stimulation, unlike traditional solid threads.

As the treatment works, these PDO microspheres are gradually broken down by the body over approximately 4 to 6 months, naturally converting into water and carbon dioxide. No material remains under the skin — only newly formed collagen, which continues to improve firmness, elasticity, and overall skin quality over time.

Why Liquid Threads Are Different (And Better in Many Cases)

1. Not a Filler

No overfilling
No “puffy” or artificial look
Results develop gradually

2. Not a Traditional Thread Lift

No physical threads
No pulling or anchoring
Minimal downtime

3. A True Regenerative Treatment

Stimulates your own collagen
Improves long-term skin quality
Works at a deeper biological level

In simple terms: Fillers add — Liquid threads rebuild.

Key Benefits of Ultracol Liquid Threads

Visible skin tightening and lifting
Improved skin density and elasticity
Reduction of fine lines and wrinkles
Brighter, more radiant skin
Natural, subtle results (no overdone look)
Minimal downtime
Suitable for delicate areas (like under eyes)

One treatment can stimulate collagen for several months, with results improving over time.

Where Can Liquid Threads Be Used?

Liquid threads are extremely versatile and can be used on:

Face

Under eyes (dark circles, hollowness)
Cheeks and mid-face
Nasolabial folds
Marionette lines
Jawline and chin
Forehead

Body

Neck tightening
Hands rejuvenation

One of its biggest advantages: It can be safely used in delicate areas where many treatments are limited.

Who Is It For?

Liquid threads are ideal for patients who:

Want lifting without surgery
Are not ready for traditional thread lift
Want natural results (not volume-heavy fillers)
Have early to moderate skin laxity
Want to improve skin quality long-term

It’s also a great preventive treatment for younger patients starting anti-aging early.

What to Expect During the Treatment

Consultation and facial assessment
Numbing cream applied
Injection process (20–30 minutes)
Minimal discomfort

After treatment:

Mild swelling or redness may occur
Most patients return to normal life immediately

Results Timeline

2–3 weeks: Skin looks fresher
1–2 months: Collagen production increases
3–6 months: Full lifting and tightening effect

Results typically last:6–12 months or longer, depending on skin condition and lifestyle

PDO gradually dissolves, but the collagen it creates remains.

Ultracol vs Fillers vs Sculptra — What’s the Difference?

Treatment	Main Function	Results	Best For
Ultracol (Liquid Threads)	Collagen stimulation + subtle lift	Gradual, natural	Skin quality + tightening
Hyaluronic Acid Fillers	Volume replacement	Immediate	Contouring, lips, deep folds
Sculptra (PLLA)	Collagen stimulation	Gradual	Volume + structural aging

Ultracol is often preferred for:

Natural results
Delicate areas
Skin tightening without heaviness

Why Liquid Threads Are Trending Globally

The rise of treatments like Ultracol reflects a major shift in aesthetics:

Less focus on artificial volume More focus on regeneration and longevity

Patients today want:

Subtle, refined improvements
Healthy skin, not overfilled faces
Long-term anti-aging solutions

Liquid threads fit perfectly into this new generation of aesthetic medicine.

Are Liquid Threads Safe?

Yes—when performed by experienced medical professionals.

PDO has been used in medicine for decades and is:

Biocompatible
Fully biodegradable
Low risk of allergic reaction

Side effects are usually mild and temporary:

Slight swelling
Minor bruising
Temporary sensitivity

Combination Treatments, Advanced Approach at EDEN AESTHETICS Clinic

For optimal results, liquid threads can be combined with:

RF microneedling
Endolift
Skin boosters
PRP / exosomes
Laser treatments

This allows for multi-layer skin rejuvenation, addressing:

Structure
Texture
Elasticity
Glow

FAQs about Liquid Threads

Is Ultracol painful?

The procedure is generally well tolerated. A topical numbing cream is applied before treatment to minimize discomfort. Most patients describe the sensation as mild pressure or slight stinging rather than pain.

How many sessions do I need?

This depends on your skin condition, age, and treatment goals. In many cases, one session already delivers visible improvement, but a course of 2–3 sessions spaced a few weeks apart provides more optimal and longer-lasting results.

Does it replace fillers completely?

No, it does not replace fillers entirely. Fillers are used to restore volume and contour specific areas, while Ultracol focuses on improving skin quality, firmness, and collagen production. In many cases, they complement each other.

Can it be used under the eyes?

Yes, one of the key advantages of liquid threads is that they can be safely used in delicate areas like under the eyes. It helps improve skin thickness, fine lines, and overall texture without adding heaviness.

When will I see results?

Initial improvement can be noticed within 2–3 weeks. However, the most significant results develop gradually over 1–3 months as collagen production increases.

How long do the results last?

Results typically last between 6 to 12 months, and in some cases longer. This depends on factors such as age, skin condition, lifestyle, and whether maintenance sessions are performed.

Is there any downtime after the treatment?

Downtime is minimal. Some patients may experience slight swelling, redness, or small bruises at injection points, which usually resolve within a few days. Most people return to normal activities immediately.

Who is not a good candidate for liquid threads?

Patients with severe skin laxity, active skin infections, or certain medical conditions may not be ideal candidates. A professional consultation is essential to determine suitability.

Can it be combined with other treatments?

Yes, and this is often recommended. Combining Ultracol with treatments like RF microneedling, laser therapies, PRP, or exosomes can significantly enhance results by targeting multiple layers of the skin.

Is the treatment safe long-term?

PDO has a long history of safe use in medicine. It naturally dissolves in the body over time, and the collagen produced remains. When performed by experienced practitioners, it is considered a safe and effective treatment.
