What happens at a lip filler consultation?
FDA's framing is blunt: having filler injected should be considered a medical procedure, not a cosmetic treatment.
The agency advises choosing a licensed health care provider who has dermatology or plastic-surgery experience and is trained in filler injection.
The first appointment is mostly questions.
FDA says people should tell the provider about bleeding disorders, severe allergies or anaphylaxis, and allergies to lidocaine, collagen, eggs, animal products or bacteria.
Expect screening on age and medical history too.
FDA states that dermal fillers are approved for adults aged 22 or older, with each product's label setting the exact age, and that filler safety is unknown during pregnancy, while breastfeeding, in people under 22 and in people prone to keloid or hypertrophic scarring.
This is also the appointment to describe the look you want and hear what the provider would use.
For the products themselves and how long each lasts, our lip filler guide covers the treatment as a whole.
How should you prepare for a lip filler appointment?
Book around your calendar first.
Cleveland Clinic advises scheduling the procedure at least two weeks ahead of a big event.
Check your lips in the days before, too: FDA says filler treatment should be delayed if the skin is inflamed or infected.
If you get cold sores, say so when you book.
The Restylane Kysse instructions warn that injections into patients with a history of previous herpetic eruption may be associated with reactivation of the herpes.
For anything else — supplements, medication, a workout that morning — ask the office what they want you to change.
Every instruction below is about the hours after treatment, not before.
The lip filler procedure, step by step
On the day, the treatment comes down to a series of small injections into and around the lip.
The steps below follow the product labels and the trial data rather than any one clinic's routine.
Lip reactions after initial treatment
Share of subjects reporting each reaction

- The injectionAllergan says Juvéderm filler is injected into the treatment area by a licensed specialist using a needle or a cannula. The gel is hyaluronic acid — a sugar FDA describes as naturally present in skin and cartilage, made for filler from bacteria or rooster combs and often crosslinked to last longer.
- What you will feelTenderness is expected, not a surprise. In the Restylane Kysse pivotal trial, 87.4% of subjects reported tenderness, 90.2% swelling and 85.8% bruising after the initial treatment; most reactions were tolerable and lasted less than 2 weeks.
- The first lookAllergan says Juvéderm results are visible immediately after treatment. Day one in the mirror is swollen day one, though — the swelling is part of what you are seeing.
- Before you leaveAsk for the aftercare instructions in writing and confirm the follow-up. Cleveland Clinic says a follow-up visit is typically scheduled about two weeks later to review the final result.
Lip filler marketing can promise a comfortable, effortless treatment. The Restylane Kysse trial data do not back that: 87.4% of subjects reported tenderness and 90.2% swelling after their initial treatment, most lasting under 2 weeks. Expect a few tender, puffy days, and treat a clinic that promises none of them with caution.

What to expect right after lip filler
The first days are about swelling, tenderness and bruising.
Cleveland Clinic says lip filler swelling usually goes away after 24 to 48 hours but may take up to a week, and that injection pain should fade after 12 to 24 hours.
The Kysse trial numbers sit on the same timeline: most injection-site reactions were tolerable and lasted less than 2 weeks.
- No makeup on the treated area for 12 hours (Juvéderm labeling)
- Minimize strenuous exercise, extensive sun or heat, and alcohol for the first 24 hours (Juvéderm labeling)
- Ice for up to 10 minutes (Cleveland Clinic)
- No lipstick, lip balm or other lip products for at least 24 hours (Cleveland Clinic)
- No touching or puckering the lips — including kissing and straws (Cleveland Clinic)
- No exercise, alcohol, smoking or straws for at least 24 hours (Cleveland Clinic)
- Minimize excessive sun, UV lamps and extreme cold until initial swelling and redness resolve (Restylane Kysse instructions)
These rules come from two product labels and one hospital's patient page, and they do not add up to a single standard.
Your own provider's written instructions are the ones to follow, and a visit about two weeks later is when Cleveland Clinic says the final result gets reviewed.
FDA calls unintentional injection into a blood vessel the most concerning filler risk: rare, but able to cause tissue death, vision problems including blindness, and stroke, with damage that may be permanent. FDA says to seek immediate medical attention for unusual pain, vision changes, white, gray or blue skin near the injection site, or signs of a stroke, during or shortly after a filler injection.
What should you ask before you book?
A first consultation is also your chance to interview the office.
Four questions map directly onto what FDA and the published evidence say:
- Who will do the injecting, and what is their filler training? FDA advises a licensed health care provider with dermatology or plastic-surgery experience who is trained in filler injection.
- Which product, and is it approved for lips? Lip approval is product-specific: Restylane Kysse, for example, is approved for lip augmentation and correction of upper perioral lines in patients over 21, while Juvéderm Ultra Plus XC has no lip indication at all.
- What do you keep on hand for emergencies? Expert reviews of filler complications call prompt recognition and immediate treatment with hyaluronidase the mainstay of managing hyaluronic acid filler occlusion, and recommend an in-office action protocol with the agents readily available.
- How much filler are you planning? No label we checked sets a standard amount for lips; Cleveland Clinic says about 1 mL is injected into the lips on average. In the Kysse trial, the median volume for initial plus touch-up treatment was 0.90 mL in the upper lip and 0.80 mL in the lower lip, and a provider should be able to explain the amount they have in mind.
Published lip filler volumes (not a recommended dose)
| Figure | Volume | Source |
|---|---|---|
| Upper lip, initial plus touch-up (median) | 0.90 mL | Restylane Kysse trial |
| Lower lip, initial plus touch-up (median) | 0.80 mL | Restylane Kysse trial |
| Retreatment, all areas (median) | 1.30 mL | Restylane Kysse trial |

Frequently asked questions
How old do you have to be to get lip filler?
FDA describes dermal fillers as approved for adults aged 22 or older — over the age of 21, in the agency's wording — with each product's label setting the exact age.
FDA also says filler safety is unknown in people under 22, during pregnancy and while breastfeeding.
A consultation is where a provider checks your history against this.
Will I see results from lip filler right away?
Allergan says Juvéderm results are visible immediately after treatment.
Day one is not the settled result, though: in the Restylane Kysse trial, 90.2% of subjects reported swelling and 87.4% tenderness after the initial treatment, and Cleveland Clinic says swelling usually goes away after 24 to 48 hours but may take up to a week.
Cleveland Clinic says a follow-up to review the final result is typically scheduled about two weeks later.
How much filler do you need for lips the first time?
No label we checked sets a standard amount for lips.
Cleveland Clinic says about 1 mL of filler is injected into the lips on average.
The other concrete figures are trial medians: in the Restylane Kysse pivotal trial, the median volume for initial plus touch-up treatment was 0.90 mL in the upper lip and 0.80 mL in the lower lip, and the median at retreatment was 1.30 mL — medians from a trial, not a recommended amount for any individual.
Ask a provider to explain the amount they plan for you.
