A Journey to Beauty Turns into a Recurring Nightmare?
Recently, a patient arrived at my clinic looking exhausted. Years ago, seeking fuller cheeks, she had a vial of collagen stimulator injected (such as Ellansé, AestheFill, or Sculptra). At first, the results were great, but it soon turned into a nightmare.
She discovered that whenever she stayed up late, or even caught a mild cold, her under-eyes and cheeks would swell up like "bread." Once the swelling subsided, it left behind two palpable, hard nodules.
To eliminate these lumps, she endured severe pain at other clinics, undergoing multiple steroid injections and at least 10 rounds of 5-FU (a chemotherapy drug).
"Doctor, it hurts so much. I’ve had so many injections, why are the lumps still there? Why does it swell up every time I get sick?"
This is not an isolated case. It is a shared pain among many patients who have received non-hyaluronic acid fillers. Today, we will look from a medical perspective at why her lumps were still there after so many injections, and what the next step can be when treatment hits a plateau.
Why Does My Face Swell When I Catch a Cold or Stay Up Late?
Many patients are told this is just "residual swelling" or "inflammation" that will pass with anti-inflammatory meds. However, it often recurs. In medicine, this is known as Delayed Onset Nodules (DONs).
Recurrent swelling has more than one possible cause, and a biofilm is one of the possibilities that needs to be evaluated.
The Vicious Cycle of Biofilms
When a filler is injected, bacteria may form a protective layer (biofilm) on the surface of the implant.
| State | Body’s Reaction |
|---|---|
| Normal Immunity | Bacteria are suppressed; no obvious symptoms. |
| Sick/Fatigued | Immunity drops, bacteria become active, triggering an immune attack. |
| Result | Recurring redness, swelling, and heat at the injection site. |
This explains why the patient swelled up "every time she caught a cold"—because the filler triggering the reaction was still inside her body.
Why Did 10 Rounds of 5-FU and Steroids Fail?
For many doctors, the standard approach to lumps is to inject Corticosteroids or 5-FU (5-Fluorouracil, an antimetabolite drug that inhibits cell proliferation). Literature shows these drugs can inhibit fibroblasts and temporarily shrink granulomas.
However, for stubborn nodules caused by collagen stimulators, simple injections often fail for three reasons:
Three Reasons Why Drug Therapy Fails
| Reason | Explanation |
|---|---|
| 1. Treats Symptoms, Not Root Cause | Drugs thin the "fibrous tissue" wrapping the filler, making the lump feel smaller, but they cannot remove the filler itself (the "core" stimulating the inflammation). |
| 2. Cannot Penetrate Biofilm | If a biofilm has formed, drugs struggle to penetrate it to kill bacteria. Once the drug wears off, the inflammation returns. |
| 3. Risk of Side Effects | Long-term or excessive steroid injections can cause skin depressions (dents) and spider veins. 5-FU injections are usually very painful and can cause tissue ulcers. |
💡 Dr. Ta-Ju Liu Explains:
"It’s like having sand in your shoe that blisters your foot. You keep applying ointment and painkillers (5-FU), but you never shake the sand out (remove the filler). The foot will never heal."
The Liusmed Solution: Ultrasound-Guided Minimally Invasive Extraction
Faced with the dilemma of "drugs don’t work, but surgery leaves scars," Liusmed Clinic utilizes an "Interventional Approach" that bridges the gap between injectable treatments and surgery.
Step 1: Ultrasound Guidance — A Window Beneath the Skin
We refuse to treat blindly. Before touching the patient, we use High-Frequency Ultrasound to scan the area:
Identify Material: Distinguish between Hyaluronic Acid, Collagen Stimulators, or fibrous scar tissue.
Locate Depth: Determine if the lump is attached just under the skin or buried deep near muscles and vessels.
Avoid Danger: Precisely map the infraorbital nerve and facial arteries to make treatment safer.
Step 2: Pinhole Extraction — Precision Craftsmanship
Unlike traditional surgery requiring large incisions, we access the area through a tiny pinhole:
Micro-Dissection: Under real-time ultrasound guidance, nerves and vessels are separated from the lump along tissue planes.
Micro-fragmentation and pinhole suction: Stubborn lumps or polymer aggregates are broken up and then suctioned out through the same pinhole.
Core Value: Removing the Root Cause
The value of this technology is simple: It removes the primary cause of inflammation. Once most of the foreign material triggering the reaction has been removed, the recurring immune response usually decreases as well.
Comparison: Drug Therapy vs. Minimally Invasive Extraction
| Feature | Steroid/5-FU Injections | Ultrasound-Guided Extraction |
|---|---|---|
| Mechanism | Inhibits inflammation, shrinks fibrosis | Physically removes the foreign body |
| Sessions | Requires multiple repeated injections | Depends on the extent of the lesion; may need staged sessions |
| Pain Level | 5-FU is extremely painful | Substantially reduced discomfort under local anesthesia plus gentle pain-relief anesthesia |
| Recurrence | High (foreign body remains) | Usually reduced once most of the foreign material is removed |
| Recovery | Swelling for days after each shot | Swelling and bruising subside in about 2-3 weeks; about 3 months overall |
| Side Effects | Risk of dents, ulcers | Tiny pinhole (heals in about 2 weeks, fades over about 2 months); some risk of scarring and tissue injury remains |
Frequently Asked Questions (FAQ)
Q1: Can collagen stimulator lumps be dissolved with drugs?
A1: Unlike Hyaluronic Acid, collagen stimulators (Ellansé, AestheFill, Sculptra) cannot be dissolved with an enzyme (Hyaluronidase). Drug therapy only temporarily shrinks the surrounding fibrous tissue but cannot eliminate the filler itself. If repeated injections fail, extraction should be considered.
Q2: Will the extraction surgery leave a noticeable scar?
A2: The minimally invasive pinhole technique used at Liusmed Clinic involves a wound usually smaller than 2mm. The pinhole heals in about two weeks and fades over about two months, though how it scars still depends on your skin. In contrast, the skin damage from living with the lumps for a long time or from repeated injections is often more noticeable.
Q3: Can all collagen stimulator lumps be removed?
A3: Most can be removed through a pinhole, but usually not all at once. The first session typically removes about 30-50%, and for most fillers about 80-90% can be removed over two to three sessions. We cannot promise that every last bit will come out, and sessions are spaced about 3 months apart. If the filler is deeply fibrosed and fused with tissue, extremely widespread, or located in high-risk zones (like inside the orbit), individual assessment is required.
Q4: Will my cheek look sunken after removal?
A4: The goal of removal is a balanced overall contour. Not everything has to come out: we remove only the parts that stick out and smooth what remains so it sits flat and even. There may be a slight depression initially (due to the removal of the foreign body volume), which usually improves gradually as the tissue heals; it takes about 3 months to see the final result, and this varies from person to person. If filling is needed, we decide at a follow-up visit after about 3 months.
Q5: What is the recovery time?
A5:
Day of Surgery: Avoid strenuous exercise.
1-3 Days: Swelling; ice packs recommended.
About 2-3 Weeks: Swelling and bruising subside; the final result takes about 3 months and varies from person to person.
Conclusion: Don’t Let the Wrong Treatment Prolong Your Pain
Returning to that patient—after the ultrasound-guided extraction, we removed white granular matter mixed with fibrous tissue from deep within her cheek.
One month later, at her follow-up visit, she told me:
"Doctor, I finally don’t have to worry about catching a cold anymore. The fear that my face might swell up at any moment is finally gone." (Individual case; results vary.)
If you are suffering from Ellansé lumps, AestheFill nodules, or recurring facial swelling, please stop enduring treatments that are painful and not working. "Extraction" may sound intimidating, but under ultrasound guidance, it deals with the source of the problem, which is a different approach from repeated drug injections.
