Most people spend more time researching a new phone than they do vetting the person who's about to put a needle in their face. That's backwards, considering one of these decisions is reversible in a week and the other genuinely affects your appearance for months.
A proper consultation isn't just a formality before treatment, it's your one real opportunity to figure out whether this practitioner actually knows what they're doing. Here are the nine questions worth asking before you commit to anything, and why each one matters more than it might seem at first.
1. What Are Your Qualifications and Are You Registered?
This is the single most important question on the list, and it's the one people skip most often because it feels awkward to ask directly. In the UK, look for practitioners registered with the GDC, GMC, or NMC, meaning they're a qualified dentist, doctor, or nurse prescriber respectively.
An unregistered injector might still be competent, but you have far less recourse if something goes wrong, and regulatory bodies exist precisely to hold medical professionals to a consistent safety standard. Any practitioner confident in their training will answer this question immediately, without hesitation or vague deflection.
2. How Many Lip Filler Treatments Have You Performed?
Experience matters enormously with lip filler specifically, since lip tissue is more mobile and vascular than most other facial areas, which makes technique genuinely harder to get right. A practitioner who's done hundreds of treatments has developed judgment about proportion and technique that someone newer simply hasn't had time to build yet.
You're not trying to catch anyone out here. You just want a sense of whether this person treats lips regularly as part of their core practice, or occasionally as one of many services they offer.
3. What Product Will You Be Using and Why?
Not all fillers are interchangeable. Different hyaluronic acid formulations are engineered for different tissue depths and purposes, and a good Dermal Lip Filler treatment depends on selecting the right product for your specific lip tissue rather than whatever happens to be available that day.
Ask for the specific brand name, whether it's CE marked, and why that particular product suits your goals. A practitioner who can explain their product choice in plain terms is demonstrating real clinical knowledge, not just following a script.
4. Can I See Before and After Photos of Similar Lip Shapes to Mine?
Portfolio photos matter, but only if they're relevant to your situation. Someone with naturally full lips getting subtle refinement looks nothing like someone with thin lips seeking significant volume, and a practitioner's results with one don't necessarily predict their results with the other.
Ask specifically for examples that match your starting point as closely as possible. This gives you a realistic preview of what this particular injector's work actually looks like on lips similar to yours, rather than a generic highlight reel.
5. What Technique Will You Use, Needle or Cannula?
Both needle and cannula techniques are used in modern lip filler treatment, and each has its place depending on the specific area being treated. Cannula technique, using a blunt tipped instrument, tends to reduce bruising and swelling since it moves around blood vessels rather than through them.
A practitioner who can explain their technique choice and why they're using it for your particular treatment plan is showing thoughtful, individualized care rather than a one size fits all approach.
6. How Much Volume Do You Recommend, and Why That Amount?
This question gets at the heart of avoiding an overfilled result. A skilled practitioner won't just ask how much filler you want, they'll assess your natural lip shape, facial proportions, and goals before recommending a specific volume tailored to you.
Be wary of anyone who agrees immediately to whatever volume you initially suggest without pushing back or asking clarifying questions first. The best injectors sometimes recommend less than what you initially asked for, particularly for a first treatment, and that restraint is usually a good sign rather than a red flag.
7. What Does Aftercare Look Like, and What Should I Watch For?
A thorough practitioner will walk you through expected swelling, bruising timelines, and activity restrictions before you ever leave the clinic. They should also tell you clearly what's considered normal versus what warrants an urgent call back, such as unusual color changes, severe pain, or firmness that doesn't resolve within a reasonable timeframe.
Vague or rushed answers here suggest aftercare isn't being prioritized, which matters more than people realize since most complications become manageable when caught and addressed early.
8. Is a Follow Up Review Appointment Included?
Results need roughly two weeks to fully settle, so a proper review appointment scheduled after that window lets your practitioner check symmetry and address any concerns while there's still time to make adjustments. Ask whether this is included in your treatment cost or billed separately, since policies vary significantly between clinics.
A practitioner who builds in follow up as standard practice, rather than treating it as optional, is generally more invested in your long term results than in just completing the transaction.
9. What Happens if I Want to Explore Other Areas Later?
Lips are often just the starting point for people exploring facial aesthetics. If you're curious about balancing your lower face with additional volume down the line, it's worth asking whether the clinic offers a broader consultation approach covering areas like Dermal Filler Cheeks, Jawline & Chin, since a practitioner who understands your whole face can plan more cohesively than one who only ever looks at the feature in front of them.
This isn't about pressuring yourself into more treatment than you want. It's about understanding whether this practitioner thinks about facial balance holistically or treats each area as a completely separate transaction.
Reading the Room During Your Consultation
Beyond the specific answers you get, pay attention to how the conversation feels overall. Does the practitioner listen to your concerns, or do they seem to be steering you toward a predetermined treatment plan regardless of what you actually said? Do they seem rushed, or do they take genuine time to assess your face and answer questions thoroughly?
A consultation that feels transactional, where you're pushed toward booking before your questions are fully answered, is worth a second thought. The practitioners worth trusting with a needle near your face are usually the ones comfortable slowing down and making sure you feel informed rather than persuaded.
Why This Matters More in a Crowded Market
Aesthetic treatments have become increasingly accessible, which is mostly a good thing, but it also means the range of practitioner skill and qualification varies more widely than ever. Clinics offering established Aesthetic Treatments London patients have researched and trust tend to welcome these questions rather than treating them as an inconvenience, since transparency is generally a sign of genuine confidence in the quality of care being offered.
Asking these nine questions doesn't make you a difficult patient. It makes you an informed one, and any practitioner worth booking will respect that.
The Bottom Line
Filler results depend far more on the skill and judgment of the person holding the needle than on the specific product used. Taking ten extra minutes during your consultation to ask direct questions is a small investment that meaningfully reduces your risk of an outcome you're not happy with.
If you'd like a consultation where these questions get answered clearly and honestly before you commit to anything, book an appointment with Cavendish Clinic. A good practitioner welcomes scrutiny, and you deserve answers before you sit in the chair.
