Introduction
If you are considering lip fillers, you may have spent time researching the procedure online — reading about techniques, results, recovery, and what to expect. One question that is often overlooked, however, is equally important: what should you tell your practitioner before the treatment begins?
Before lip filler treatment, sharing accurate and complete information during your consultation is one of the most important steps in the process. A thorough pre-treatment discussion helps your practitioner assess whether the procedure is appropriate for you, identify any potential risks, and tailor the approach to your individual anatomy and goals.
Lip fillers — most commonly formulated with hyaluronic acid — are among the most frequently requested aesthetic treatments in the UK. While they are generally well tolerated, they are not without risk, and outcomes vary considerably between individuals. Understanding what to disclose before having lip fillers can meaningfully contribute to a safer experience and more informed decision-making.
This article outlines the key information patients are typically asked to share before a lip filler consultation, and why each element matters.
What Should You Tell Your Practitioner Before Having Lip Fillers?
Before having lip fillers, you should inform your practitioner about your full medical history, current medications, allergies, any previous filler treatments, lifestyle factors such as smoking, and your aesthetic goals. Sharing this information before lip filler treatment enables your practitioner to assess suitability, manage potential risks, and personalise your care appropriately.
Your Medical History: Why It Matters More Than You Might Think
When preparing for a lip filler consultation, your medical history is one of the most critical pieces of information your practitioner will need. This goes well beyond simply mentioning any major illnesses. You should be prepared to discuss:
- Autoimmune conditions such as lupus, rheumatoid arthritis, or Sjögren's syndrome, as these may influence healing and treatment suitability
- Blood clotting disorders or a tendency to bruise or bleed easily
- Skin conditions affecting the lips or surrounding area, including cold sores (herpes simplex virus), as filler treatment can trigger an outbreak
- A history of keloid scarring or hypertrophic scarring
- Dental work or planned dental procedures, which may influence the timing of treatment
- Any ongoing or recent infections, particularly in or around the mouth
- Immunosuppression, whether due to a medical condition or medication
None of this information is shared to exclude you from treatment automatically. Rather, it allows your practitioner to make an informed clinical decision about timing, technique, and appropriate precautions. Concealing relevant medical history can increase your risk unnecessarily, so open communication is always encouraged.

Medications, Supplements, and Herbal Remedies
Many patients are surprised to learn that certain everyday medications and supplements can increase the risk of bruising and swelling following lip filler treatment. Before your appointment, you should inform your practitioner of:
- Prescription medications, including anticoagulants (blood thinners) such as warfarin or newer anticoagulants (DOACs), antidepressants, and hormone treatments
- Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or aspirin, which can impair platelet function and increase bleeding risk
- Herbal supplements including fish oil, vitamin E, evening primrose oil, ginkgo biloba, and garlic supplements — all of which can have blood-thinning effects
- Any recent or planned vaccinations, as some practitioners prefer to allow a gap between vaccines and filler treatment
- Antiviral medications, which may be relevant if you have a history of cold sores
Your practitioner may advise you to pause certain supplements ahead of treatment where it is safe to do so, but you should never stop prescribed medication without first consulting your prescribing doctor.
Previous Aesthetic Treatments and Filler History
If you have previously had lip fillers or any other facial aesthetic treatments, this information is essential for your practitioner to know. Prior treatment history can affect:
- How much product remains in the lips from previous sessions (hyaluronic acid fillers break down over time but residual product can remain)
- The technique used, as a practitioner will adapt their approach based on existing anatomy and previous work
- Potential complications from prior treatments, including any asymmetry, lumps, migration of product, or vascular events
You should also inform your practitioner if you have previously had permanent or semi-permanent fillers, as these carry different management considerations compared to hyaluronic acid-based products. If you have experienced any adverse reactions to fillers in the past — including pain, prolonged swelling, skin changes, or signs of vascular compromise — these must be disclosed before proceeding. Understanding lip filler migration, prevention, and treatment can also help you describe any changes you have noticed since an earlier procedure.
Honest disclosure of your aesthetic treatment history is not a source of judgement. It is foundational to planning treatment safely.
Allergies and Sensitivities
Allergy disclosure is a standard and essential part of any pre-treatment health assessment. Before having lip fillers, inform your practitioner of:
- Known allergies to any medications, including local anaesthetics such as lidocaine (which is commonly incorporated into hyaluronic acid filler formulations)
- Allergies to any skincare products or topical preparations
- Previous allergic reactions to aesthetic or cosmetic treatments
- Any food allergies, particularly if severe, as some individuals with multiple sensitivities may benefit from additional allergy assessment prior to treatment
Although true allergic reactions to modern hyaluronic acid fillers are uncommon, they can occur, and knowing your allergy history allows your practitioner to prepare appropriately and select the most suitable product for your needs.

Lifestyle Factors That May Affect Your Treatment
Certain lifestyle habits can influence both the safety and outcomes of lip filler treatment. Your practitioner may ask about:
- Smoking, which can impair circulation, slow healing, and may affect how the skin and soft tissues respond to treatment
- Alcohol consumption, including whether you have consumed alcohol recently, as this can increase bruising risk
- Sun exposure history and current skincare habits, which provide useful context for your overall skin health
- Exercise habits, as high-intensity physical activity shortly before or after treatment may exacerbate swelling and bruising
- Diet and hydration, as these can influence tissue health and recovery
You should also mention if you are pregnant or breastfeeding, as lip filler treatment is not considered appropriate during these periods and qualified practitioners will not proceed without this information being clarified.
Lifestyle disclosures are not about passing judgement on personal choices. They are about understanding the individual context in which treatment is being considered, so that your practitioner can advise you accordingly.
Your Aesthetic Goals and Expectations
One of the most important — yet sometimes underemphasised — aspects of a pre-treatment consultation is the open discussion of what you are hoping to achieve. Before having lip fillers, be prepared to share:
- What specifically you would like to address — for example, increased volume, improved symmetry, enhanced definition of the lip border, or subtle reshaping
- Your aesthetic preferences, including whether you are looking for a natural enhancement or a more noticeable change
- Reference images, if helpful, while being mindful that anatomical differences mean results will vary between individuals
- Any concerns about asymmetry that you have noticed
- Your timeline, including any upcoming events or commitments that may influence treatment scheduling
A skilled practitioner will use this information to have an honest discussion with you about what is realistically achievable based on your individual lip anatomy, skin quality, and facial proportions. Exploring lip filler options at Pantaleo with a qualified practitioner can help you understand how treatment can be tailored to your specific anatomy and goals.
It is equally important to discuss any concerns or apprehensions you have about the procedure. A reputable practitioner will welcome these questions and ensure you feel comfortable before proceeding.
Understanding the Science Behind Lip Fillers
To appreciate why your pre-treatment disclosure matters so much, it helps to understand how lip fillers work at a biological level.
Most lip fillers used in the UK are formulated with hyaluronic acid (HA) — a naturally occurring polysaccharide found throughout the body, including in connective tissue, skin, and joint fluid. HA has a remarkable capacity to attract and retain water molecules, giving it volume-creating and hydrating properties. When injected into the lips or surrounding tissue, it temporarily adds structure, definition, and fullness.
As we age, the body's natural production of hyaluronic acid declines. This contributes to volume loss, reduced skin hydration, and the development of fine lines around the mouth — sometimes referred to as perioral lines. The lips themselves can become thinner, with less defined borders and reduced projection over time.
Hyaluronic acid fillers are gradually broken down by the body's own enzyme hyaluronidase over a period of months. One of the clinical advantages of HA-based fillers is that this process can be accelerated by injecting additional hyaluronidase in the event of an adverse outcome or where reversal is desired — making them a safer option compared to permanent alternatives.
Because filler is introduced into a highly vascularised area of the face, understanding a patient's circulatory health, medication use, and anatomical history is directly relevant to minimising risk.

Mental Health and Psychological Wellbeing
Responsible aesthetic practice includes consideration of a patient's emotional wellbeing and motivations for seeking treatment. Your practitioner may gently explore:
- Your reasons for considering treatment and whether they align with realistic expectations
- Whether you are in a good psychological place to make an informed decision
- Whether external pressures — such as social media, peer influence, or relationship dynamics — are playing a significant role in your decision
This is not intended to be intrusive. Rather, it reflects the ethical duty of care that qualified practitioners hold. Reputable practitioners will not proceed with treatment if they have concerns about a patient's psychological readiness or if the treatment goals appear to be driven by unrealistic expectations or distress.
If you are experiencing concerns about your appearance that are significantly affecting your daily life or mental wellbeing, speaking with your GP or a mental health professional may be a more appropriate first step before considering aesthetic treatment.
Who May Benefit from a Professional Consultation?
A pre-treatment consultation for lip fillers is appropriate for anyone who is curious about the procedure, even if they are not yet certain whether they wish to proceed. You may find a professional consultation particularly helpful if:
- You have specific concerns about the appearance or symmetry of your lips
- You have experienced volume loss in the lips associated with the natural ageing process
- You have questions about how lip fillers might interact with previous treatments you have had
- You are unsure whether lip fillers or an alternative approach — such as anti-wrinkle injections for perioral lines — may better address your concerns
- You would like to understand the risks and realistic outcomes before making a decision
A consultation is an opportunity to ask questions and gather information — not a commitment to proceed. Patients are always encouraged to take time to consider their options and return for treatment only when they feel confident and well informed.
Realistic Benefits, Limitations, and Expectations
It is important to approach lip filler treatment with balanced expectations. Understanding both the potential benefits and the limitations of the procedure is an essential part of informed consent.
Potential benefits may include: Enhanced lip volume and fullness Improved definition of the lip border (vermillion border) Improved symmetry in some cases Softening of fine lines immediately around the mouth
Realistic limitations to be aware of: Results are temporary and typically last between six and twelve months, depending on the product used, the volume injected, individual metabolism, and lifestyle factors Results vary significantly between individuals due to differences in anatomy, skin quality, and technique Swelling and bruising following lip filler treatment are common and may temporarily make results appear different from the final outcome Achieving a desired result may require more than one treatment session
Individual variation is significant. Factors such as age, skin condition, lip anatomy, lifestyle habits, and previous filler history all influence the outcome. No two patients will achieve identical results, and no practitioner can guarantee a specific appearance.

Aftercare and Skin Health Following Lip Fillers
If you proceed with lip filler treatment, your practitioner will provide personalised aftercare guidance. General educational information that is commonly shared includes:
- Avoiding high-intensity exercise for at least 24–48 hours following treatment to minimise swelling and bruising
- Avoiding alcohol for at least 24 hours post-treatment
- Avoiding extreme heat, including saunas, steam rooms, and prolonged sun exposure, in the days following treatment
- Keeping the treated area clean and avoiding unnecessary touching or pressing of the lips
- Applying sun protection to the face as part of a daily skincare routine to support overall skin health and longevity of results
- Staying well hydrated, which supports tissue health generally
- Attending any scheduled follow-up appointments to allow your practitioner to assess the results and address any concerns
If you notice any unusual symptoms following treatment — including severe pain, blanching of the skin, unusual discolouration, or visual changes — you should contact your treating practitioner promptly, as these may be signs of a rare but serious complication requiring urgent attention. Pantaleo's consultation service provides a thorough pre- and post-treatment support framework to help patients feel informed and cared for throughout their journey.
Key Points to Remember
- Sharing complete and accurate medical information before lip filler treatment is essential for patient safety and appropriate treatment planning.
- Medications, supplements, and allergy history should always be disclosed, as they can directly influence treatment safety and outcomes.
- Previous filler treatments and aesthetic history help your practitioner understand your individual starting point and plan accordingly.
- Lifestyle factors, including smoking, alcohol use, and upcoming events, are relevant to both timing and recovery.
- Realistic expectations are best developed through open discussion with a qualified practitioner — individual results vary considerably.
- A consultation is not a commitment to proceed; it is an opportunity to make an informed, unhurried decision.
Frequently Asked Questions
Do I need to stop taking any medications before having lip fillers?
You should never stop prescribed medication without first consulting your prescribing doctor. However, your practitioner may advise pausing certain over-the-counter supplements — such as fish oil, vitamin E, or ibuprofen — in the days leading up to treatment, as these can increase the risk of bruising. Always disclose your full medication and supplement list at your consultation so your practitioner can advise appropriately based on your individual circumstances.
Can I have lip fillers if I have had cold sores in the past?
A history of cold sores (herpes simplex virus) does not necessarily mean you cannot have lip fillers, but it is important information your practitioner needs to know. Filler treatment can sometimes trigger a herpes outbreak in susceptible individuals. Your practitioner may recommend a prophylactic course of antiviral medication to reduce this risk. Suitability will be assessed on an individual basis, and you should never have treatment during an active cold sore episode.
How long before my appointment should I avoid alcohol and certain supplements?
General guidance often suggests avoiding alcohol for at least 24–48 hours before treatment, and pausing blood-thinning supplements where advised by your practitioner for a period of several days beforehand. However, specific recommendations vary depending on your health profile and the products involved. Your practitioner will provide personalised guidance at your consultation, which should always take precedence over general advice.
What happens if I have had permanent fillers in the past?
If you have previously had permanent or long-lasting non-HA fillers, this is particularly important to disclose. Permanent fillers cannot be dissolved in the way that hyaluronic acid fillers can, and their presence may influence the safety and technique of any subsequent treatment. A thorough assessment will be required before your practitioner can advise on whether and how to proceed safely.
Is there anything I should avoid doing on the day of my appointment?
On the day of your appointment, it is generally advisable to arrive with clean skin, free from heavy makeup around the mouth area. You should avoid consuming alcohol beforehand, and inform your practitioner if you feel unwell, as proceeding during illness may not be advisable. Wearing comfortable clothing and allowing enough time for a relaxed consultation can also help ensure a calm and unhurried appointment experience.
How do I know if lip fillers are right for me?
The only way to determine whether lip fillers are appropriate for you is through an individualised consultation with a qualified and experienced practitioner. During this appointment, your practitioner will review your medical history, assess your lip anatomy, discuss your goals, and explain the potential benefits, risks, and alternatives relevant to your specific situation. There is no single treatment that is universally suitable, and a responsible practitioner will only recommend proceeding when it is clinically and ethically appropriate to do so.

Conclusion
Preparing for a lip filler consultation involves more than simply deciding what look you would like to achieve. Sharing comprehensive, accurate information with your practitioner — covering your medical history, medications, allergies, previous treatments, lifestyle, and realistic expectations — is a fundamental part of a safe and well-informed aesthetic journey.
Knowing what to tell your practitioner before having lip fillers enables a more personalised, clinically responsible approach to treatment planning. It supports your practitioner in identifying any factors that may affect safety or outcomes and helps ensure that you receive advice tailored specifically to you.
Aesthetic treatments, including lip fillers, are not one-size-fits-all. Individual anatomy, health status, and personal goals all shape what is possible and appropriate. Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.
If you are considering lip fillers and would like to understand whether the procedure may be appropriate for you, speaking with a qualified aesthetic practitioner is always the recommended first step.
