5 Questions to Ask Before Getting Lip Fillers
Lip filler treatments — the injection of hyaluronic acid to add volume or definition to the lips — are among the most popular aesthetic procedures in the UK. They are also among the treatments most associated with poor outcomes when performed by unqualified practitioners. The lips are a vascular area with significant aesthetic complexity; even small errors in technique can result in asymmetry, migration of product, or in rare but serious cases, vascular complications.
Asking the right questions before you book is the single most effective thing you can do to protect your safety and achieve a result you are happy with. Here are five questions that every patient should ask.
1. What Are Your Qualifications and Regulatory Registration?
This is the most important question. Under the Health and Care Act 2022, administering dermal fillers in England is restricted to registered healthcare professionals. That means your practitioner must hold a registration with a recognised professional regulatory body — such as the General Dental Council (GDC), the General Medical Council (GMC), or the Nursing and Midwifery Council (NMC).
You can verify registrations independently:
- GDC: olr.gdc-uk.org
- GMC: gmc-uk.org
- NMC: nmc.org.uk
Beyond core registration, ask about specific aesthetics training. Dentists who perform lip fillers should have completed recognised postgraduate training in facial aesthetics — not merely a one-day course. Membership of the British Academy of Cosmetic Dentistry (BACD) or listing on the Save Face accreditation register indicates a commitment to professional standards beyond minimum requirements.
Why dentists are often an excellent choice for lip fillers: their training in perioral anatomy — the area around the mouth and lips — is directly relevant. Dentists understand the vermilion border, Cupid's bow, the philtrum, and how the lips relate to the dental arches and smile aesthetics. This anatomical knowledge is not incidental; it is central to achieving natural-looking results.
2. Do You Have Hyaluronidase on Site?
Hyaluronidase is the enzyme used to dissolve hyaluronic acid fillers — for more on filler safety and what to check, see our article Is it safe to get dermal fillers from a dentist? It is the antidote to HA lip fillers and is essential for managing vascular occlusion — a serious complication that occurs when filler accidentally enters a blood vessel, restricting blood flow. While vascular occlusion is rare, it is a recognised risk of lip filler treatment given the vascularity of the perioral region.
Any competent practitioner administering lip fillers must have hyaluronidase immediately available. If a provider cannot confirm this, do not proceed with treatment there. This is non-negotiable.
Also ask: what is your protocol if I develop a complication after I leave the clinic? You should receive clear aftercare instructions, an emergency contact number, and a clear pathway to medical support if needed.
3. What Product Will You Use and Is It Licenced in the UK?
Not all dermal fillers are equal. Ask specifically which product will be used for your lip treatment and confirm it is a CE-marked or UKCA-marked medical device from a reputable manufacturer. Established HA filler brands licensed for use in the UK include Juvederm (AbbVie), Restylane (Galderma), Belotero (Merz), and Teosyal (Teoxane).
Be wary of practitioners who cannot or will not tell you which product they use, or who use unfamiliar brands at unusually low prices. Unlicensed or counterfeit filler products have been identified in the UK market and are associated with granuloma formation, infection, and other serious complications.
Also ask whether the product is specifically designed for lip augmentation. Lip tissue requires a softer, more pliable filler than areas such as the cheeks or jawline. Using an inappropriately stiff product in the lips can result in an unnatural appearance or discomfort.
4. What Results Are Realistic for Me?
A good practitioner will manage your expectations honestly. This discussion forms a key part of your initial consultation — see our guide on what to expect at your first facial aesthetics consultation. Lip fillers can enhance lip volume, improve definition, correct mild asymmetry, and restore volume lost to ageing. What they cannot do is fundamentally restructure the shape of your lips or replicate another person's anatomy.
During the consultation, your practitioner should assess your existing lip anatomy and discuss what is achievable based on your individual starting point. They should explain how much product they recommend for your first treatment — conservative initial treatment is generally considered best practice, particularly for new patients.
Note that under ASA/CAP advertising guidelines, practitioners are restricted in how they can display outcome images for filler treatments in promotional contexts. A clinical discussion of expected outcomes during your consultation is appropriate and does not fall under these restrictions.
5. What Is the Follow-Up Process?
Ask what happens after your treatment. A reputable provider will:
- Provide written aftercare instructions
- Schedule a review appointment two to four weeks post-treatment
- Be reachable if you experience unexpected swelling, pain, or skin colour changes after leaving the clinic
Significant swelling and bruising in the first 24–72 hours is common and expected. However, unusual pain, blanching (skin turning white), or mottled discolouration are warning signs of vascular compromise and require immediate contact with your practitioner.
A provider who does not offer a follow-up appointment or provide emergency contact details is not meeting the standard of care you should expect.

Frequently Asked Questions
Are lip fillers legal for beauty therapists to administer in the UK?
No. Under the Health and Care Act 2022, administering dermal fillers (including lip fillers) in England is restricted to registered healthcare professionals such as doctors, dentists, and nurses. Beauty therapists without healthcare registration cannot legally administer lip fillers in England.
Why is hyaluronidase so important for lip filler treatment?
Hyaluronidase is the antidote to hyaluronic acid fillers. It can dissolve filler in the event of a vascular occlusion — where filler enters a blood vessel — which is a rare but serious complication. Any practitioner offering lip fillers must have hyaluronidase immediately available on site.
How long do lip fillers last?
Hyaluronic acid lip fillers typically last between 6 and 12 months, though this varies between individuals based on metabolism, lifestyle, and the specific product used. Your practitioner will advise on timing for any top-up treatment.
Are dentists good practitioners for lip fillers?
Dentists have in-depth training in perioral anatomy — the area around the mouth and lips. This expertise is directly relevant to lip filler treatment, as it encompasses the vermilion border, philtrum, Cupid's bow, and the relationship between the lips and dental structures. Many patients specifically choose dentists for lip treatments for this reason.
What should I do if I experience a complication after lip fillers?
Minor bruising and swelling are normal in the first few days. If you experience unusual pain, blanching or white patches on the skin, mottled discolouration, or vision changes, contact your practitioner immediately — these can be signs of vascular occlusion requiring urgent treatment with hyaluronidase.
