How Are Biopolymers Removed? A Guide to Understanding the Procedure

What they are and why the body doesn't expel them

Biopolymers are synthetic substances—industrial liquid silicone, mineral oils, methacrylate—that were injected for aesthetic purposes by individuals without medical training. Unlike an approved filler, they are not absorbed. The body recognizes them as a foreign body and responds by encapsulating them: it forms fibrous tissue around them, and over time the material migrates due to gravity and through muscular planes to areas different from where it was injected. This explains why the problem rarely stays in one place. A patient injected in the buttocks may develop discomfort years later in the thighs or lumbar region.

Why there is no "complete extraction"

It's important to be clear: no serious surgeon promises to remove 100%. The material is not contained in a bag that can be entirely removed; it is infiltrated between tissues, mixed with fat and fibrosis. The actual goal of treatment is different and more honest: to remove as much material and compromised tissue as possible, stop the inflammatory process, and restore functionality and shape. Be wary of anyone who guarantees a total clean-up.

How the case is studied before surgery

Before any surgical decision, it's necessary to know where the material is, how much there is, and what tissues it has compromised. This is done with magnetic resonance imaging, which is the study that best differentiates biopolymer from fat and muscle. The patient's general health status is also evaluated, as many patients arrive with years of chronic inflammation. With this information, it is determined whether the case will be resolved in one surgical stage or several.

What the surgery involves

The procedure is performed in the operating room, under anesthesia, and consists of resecting the affected tissue block: the material is removed along with the surrounding fibrosis. Depending on the area and extent, it may require subsequent reconstruction to restore contour, either during the same procedure or in a second stage. Each case is planned individually. The extent of infiltration, the area, and the condition of the tissue determine the technique.

What to expect from recovery

The first few weeks involve relative rest, the use of a compression garment or binder, drains in some cases, and frequent medical check-ups. Full recovery takes months, not days, and is usually accompanied by a process of progressive improvement of inflammatory symptoms.

When to consult

If you have a history of non-medical aesthetic injections and experience hardening, pain, skin discoloration, progressive deformity, or general symptoms without a clear cause, evaluation by a certified plastic surgeon is the first step.
