Before anyone puts a needle in your face, you should get clear answers to six things: who is holding the syringe and what license they hold, which product they’ve chosen and why that one, how much they plan to use and over how many visits, whether the office keeps the enzyme that dissolves hyaluronic acid filler on site, what happens if you hate the result, and what they’d refuse to do for you. An injector who answers all six without getting defensive is the one to book. An injector who deflects on any of them has told you something useful. Filler is a medical procedure with medical risks, and the consult is where you find out what kind of practice you’ve walked into.
This isn’t an argument against filler. Plenty of people get it, love it, and never have a problem. But the industry spent a decade selling it as a lunch-break beauty service, and the consult is the part that got optimized away.
Who is holding the syringe
Who’s legally allowed to inject varies by state: physicians, PAs, nurse practitioners, and registered nurses under supervision all do it, and in some states dentists. A license says very little about skill with a needle near your eye.
If they say board certified, ask in what. Dermatology, plastic surgery, facial plastic surgery, and oculoplastics are the certifications that bear on facial injectables, and you can check the board against the American Board of Medical Specialties list. If a nurse or PA is injecting, ask who supervises them and whether that person is in the building during your treatment.
Then ask about experience with your treatment, not injecting in general — lips every day is not the same skill as tear troughs. Ask for before-and-afters of their own patients, including a set taken a year out rather than the glossy day-of photo. Last: what’s your complication protocol? A confident injector walks you through it unprompted.
Which product, and why that one
Filler is a category, not a substance. The common ones are hyaluronic acid gels — Juvederm, Restylane, RHA, Belotero — and their defining feature is that an enzyme can break them down if things go sideways. Others don’t. Poly-L-lactic acid and calcium hydroxylapatite are biostimulators that prompt your own collagen over months, and no enzyme dissolves them. Permanent microsphere products stay by design.
That matters more than the brand name. If you’re new to this, start with something reversible, so a bad outcome stays a correctable one. Ask which category they picked and why — “it’s what we use” isn’t a reason.
Ask to see the box and the sealed syringe opened in front of you: an FDA-cleared product with a lot number, not something decanted, unlabeled, or bought overseas because it was cheaper. Fillers are cleared for specific areas, and using one elsewhere is common and legal but should be said out loud. If you’re still weighing filler against a neuromodulator, which does a completely different job, we compared them in Botox vs. filler.
How much, and over how many visits
A syringe is typically one milliliter, roughly a fifth of a teaspoon. It sounds like nothing. In a face, it isn’t.
Ask how many syringes are planned today, then ask what the plan looks like over a year — the second question is the one that shapes your face. Filler is far easier to add than to remove, so a staged approach earns its extra visit: a conservative amount now, a look in the mirror two to four weeks later once swelling has resolved, then a decision about more. The overfilled look almost never comes from one visit. It comes from twelve, each reasonable on its own. Be skeptical of prepaid packages.
What dissolving can and can’t undo
Hyaluronidase, the enzyme that breaks down hyaluronic acid filler, gives people a false sense of a reset button. It’s a useful tool, and messier than the marketing suggests.
It works on hyaluronic acid only — biostimulators and permanent products don’t respond, so correcting those narrows to steroid injections, time, or surgery. And it isn’t precise: the enzyme spreads through tissue and can take down more than the deposit you targeted, including some of your skin’s own hyaluronic acid in that area. That part is temporary, but the weeks in between can look worse than where you started. It often takes more than one session.
Skin stretched by product for years doesn’t always snap back, either. It usually settles more than people fear, but reversible and erasable aren’t the same word. Ask what dissolving would involve in your case, then ask the question that says the most about a practice: is hyaluronidase kept on site, in date, in a quantity that would matter in an emergency? Our piece on what filler migration looks like covers the signs you might need it.
The risks worth saying out loud
Bruising, swelling, tenderness, and small lumps that resolve are common. The ones to understand before you consent are rarer.
The big one is vascular occlusion. If filler ends up inside a blood vessel, or presses hard enough on one, blood stops reaching the tissue that vessel feeds. Skin can turn white, then mottled and dusky, then break down and scar. Near vessels connected to the eye, vision loss is possible — very rare, and devastating. The warning signs are pain out of proportion to the injection, sudden blanching, a blotchy purple pattern in the hours after, or any change in vision, and each one is an immediate phone call rather than a wait-and-see.
Delayed inflammatory nodules can appear months after an uneventful treatment, sometimes after an illness or a vaccine, and infection is possible any time skin is punctured. Tell your injector about autoimmune conditions, blood thinners, active cold sores, and anything you’re being treated for, and expect filler to be deferred during pregnancy and nursing.
None of this is something a blog can assess for your face. That’s a conversation with a licensed medical provider who has examined you, knows your history, and is reachable at nine on a Saturday night.
Why you shouldn’t decide the same day
A consult that ends with a syringe in your face forty minutes later wasn’t a consult. It was a sales appointment with a procedure attached.
Book the conversation and the treatment as two visits, even when the office offers to do both. The gap gives you time to look up the product they wrote down, check credentials, and see whether the impulse survives the week. Ask for the plan in writing — product, areas, volume. Watch for pressure: discounts that expire today, “we already have product open,” treatment at a party or a pop-up. And don’t schedule within a few weeks of a wedding or photos, because bruising resolves on its own timeline.
What a good injector will refuse to do
The refusals are the credential. An injector who has never turned a paying patient away isn’t in the habit of saying no.
A good one declines to treat what filler can’t fix — loose skin, crepey texture, under-eye darkness that’s pigment rather than hollowness, jowls that need lifting rather than volume — and says what would help instead, including nothing. They won’t stack product on top of filler that hasn’t settled or looks like it has drifted. They’ll stop you when they think you’ve had enough, even though it costs them the sale. And they won’t promise: an exact outcome, a set duration, or zero bruising is marketing, not medicine.
If I Were You
If this is your first time, split the consult and the appointment into two visits and start with one reversible hyaluronic acid syringe in one area. You can add next month. You can’t un-inject a face.
If your concern is under-eye hollows, be pickier here than anywhere else. The tear trough is thin-skinned, close to important vessels, and unforgiving — see someone who treats it constantly, or wait.
If you’re weighing lip filler against something subtler, a flip and a syringe give different results with different downsides, which we broke down in lip filler vs. lip flip.
If you already have filler from another injector, bring the records — product names, dates, volumes. If you can’t get them, say so plainly instead of guessing; it changes what a new injector can safely do.
If price is making the decision for you, wait and save. Cheap filler usually means less product, less experienced hands, or no emergency plan.

Frequently Asked Questions
What should I ask an injector first?
What license and board certification they hold, who supervises them if they’re a nurse or PA, whether that person is on site, and how often they do the treatment you want. Then: what happens if a vessel gets blocked, and is hyaluronidase kept in the building?
Is it rude to ask to see the product box?
No, and a good injector expects it. You’re confirming the filler is an FDA-cleared product with a lot number, opened in front of you rather than decanted from something unlabeled.
Can all filler be dissolved?
No. Hyaluronidase breaks down hyaluronic acid fillers only. Biostimulators and permanent products don’t respond, so correcting those means steroids, time, or surgery. Even with hyaluronic acid, dissolving can take several sessions and isn’t precise — a repair, not an undo button.
What are the warning signs I should call about immediately?
Pain that’s severe or increasing rather than fading, skin that turns white during or after injection, a blotchy purple or dusky pattern, spreading redness with fever, or any change in vision. Call the office right away and go to an emergency room if you can’t reach anyone.
The bottom line
Filler done by someone qualified, in a conservative amount, with a written plan and an emergency protocol, is a reasonable thing to choose. Filler done fast and cheap by whoever had an opening is where the horror stories come from — and the difference is visible at the consult. Ask the six questions, take the plan home, and let a licensed provider who has examined your face make the medical call. More read-it-before-you-book coverage lives in the skin section.
