Cosmetic medicine may be the only medical field where most patient education happens on social media before it happens in a clinic. Some of what circulates is accurate; much is folklore. Here are the seven myths we hear most often — and what the evidence actually says.
Myth 1: "Filler will stretch my skin, and it will sag when it dissolves"
Fact: Appropriately dosed filler does not stretch skin. Hyaluronic-acid fillers integrate with tissue and biodegrade gradually — the skin returns towards its baseline, not worse than baseline. What creates that fear are cases of significant overfilling; the problem there is the dose, not the medicine.
Myth 2: "Everyone will know I had something done"
Fact: The filler people notice is the filler that was overdone. Well-planned treatment restores what your face had — people register "rested" or "well", not "treated". The most common comment our patients report hearing is a compliment with no question attached.
Myth 3: "Filler is permanent"
Fact: The fillers used in evidence-based practice are biodegradable and temporary — typically lasting months to about a year and a half, depending on product and area. Permanent fillers exist historically but are avoided in modern academic practice precisely because faces change and permanent materials don't.
Myth 4: "If I don't like it, I'm stuck with it"
Fact: Hyaluronic-acid filler is the one aesthetic treatment with an eraser: the enzyme hyaluronidase can dissolve it, partially or completely, when medically indicated. This reversibility is a genuine safety feature — and one reason HA is the default choice for many areas.
Myth 5: "Once you start, you can't stop"
Fact: There is no dependency mechanism. If you stop, the filler simply biodegrades and your face continues aging at its natural pace — the same pace as if you had never been treated. Patients continue because they like the result, not because stopping harms them.
Myth 6: "Anyone with a certificate can inject — it's just a syringe"
Fact: The syringe is the least important part. Safe injection is applied anatomy: knowing where facial vessels run, recognising a vascular complication in minutes, and having the training and medications to manage it. This is why regulations place injectables in licensed medical hands — and why "who is injecting" matters more than "which brand".
Myth 7: "More product = better result"
Fact: The best results usually come from restraint — the right millilitres in the right plane, sometimes across more than one session. A conservative first session with review at two weeks beats an aggressive single session every time.
- Modern fillers are temporary, biodegradable — and HA fillers are reversible.
- Natural-looking results are a dosing and planning decision, not luck.
- Stopping treatment returns you to your natural baseline; there is no rebound.
- Injector qualification is the single most important safety factor.
A closing thought
Good aesthetic medicine is quiet. It doesn't announce itself, it doesn't trend, and it starts with a doctor who will sometimes tell you no. If an answer you find online sounds too dramatic to be true — in either direction — it usually is.
