What this site is for
It exists for a question that sounds simple and is not: can this be undone? The answer depends almost entirely on what was injected, because only one substance class can be reliably dissolved. Having established that, it depends on how much is dissolved, in how many sessions, and what the face is expected to look like afterwards — which is the face as it is now without the filler, not the face as it was before.
What it deliberately does not do
It does not name brands of drugs, devices or filler products: substances are described by class only. It does not quote prices or dosages, and it does not promise that an area will return to a previous appearance or that all of the material will be removed. It does not publish an emergency telephone number, a room number or a set of opening hours of its own.
The facts kept visible
Three facts are repeated wherever they are relevant. A dissolving agent works on hyaluronic-acid filler only; calcium hydroxylapatite, poly-L-lactic acid and polynucleotides cannot be dissolved. Dissolving has its own risks, and too much of it removes the patient’s own hyaluronic acid as well as the filler. And vascular occlusion remains a time-critical emergency that can cause skin loss and, rarely, vision loss — dissolving is an injection, and the injection is where that risk lives.
