What Should You Tell Your Practitioner Before Anti-Wrinkle Injections?

If you are considering anti-wrinkle injections for the first time — or even returning for a repeat appointment — you may wonder what information your practitioner actually needs to know before treatment begins. This is a very common question, and a genuinely important one.

Anti-wrinkle injections, often associated with botulinum toxin treatments, are one of the most widely performed non-surgical aesthetic procedures in the United Kingdom. They are used to address dynamic facial lines — the kind caused by repeated muscle movement, such as frown lines, forehead lines, and crow's feet. As with any medical procedure, patient safety begins long before the treatment itself.

Understanding what to tell your practitioner before anti-wrinkle injections helps ensure your appointment is thorough, safe, and appropriate to your individual circumstances. Many patients research this online because they want to feel prepared and confident ahead of their consultation.

This article outlines the key medical, lifestyle, and personal information you should be ready to discuss — and explains why each element matters to the practitioner assessing your suitability.

Before anti-wrinkle injections, you should tell your practitioner about your full medical history, current medications and supplements, previous aesthetic treatments, any allergies, pregnancy or breastfeeding status, and relevant lifestyle factors such as smoking. Sharing this information helps your practitioner assess your suitability safely and plan your treatment appropriately.

The consultation before anti-wrinkle injections is not simply a formality — it is a clinically important step that informs whether treatment is appropriate for you at all, and if so, how it should be approached.

A thorough consultation allows your practitioner to:

• Understand your concerns and aesthetic goals
• Review your medical history in detail
• Identify any contraindications or risk factors
• Discuss realistic outcomes and limitations
• Answer your questions and address concerns
• Obtain your informed consent

Botulinum toxin is a prescription-only medicine. It may only be supplied and administered following an individual clinical assessment and prescription by an appropriately qualified prescriber. The consultation must also support informed consent and discussion of reasonable alternatives, risks, and expected outcomes.

This article provides factual educational information only. It does not advertise or recommend a prescription-only medicine, and it does not imply that any product or treatment will be prescribed. Any decision can be made only after an individual clinical assessment.

It is worth remembering that treatment suitability depends entirely on individual assessment. What is appropriate for one person may not be appropriate for another. A thorough consultation protects you and helps ensure any treatment undertaken is in your best interest.

One of the most important aspects of any pre-treatment consultation is your medical history. Even if you consider yourself generally healthy, certain conditions are directly relevant to anti-wrinkle injections.

Conditions you should always mention include:

• Neuromuscular disorders such as myasthenia gravis, Lambert-Eaton syndrome, or motor neurone disease. These conditions affect how muscles respond and may make botulinum toxin treatments unsuitable.
• Autoimmune conditions, particularly those affecting muscles or nerves.
• Bleeding disorders or conditions that affect how your blood clots.
• Facial nerve conditions, including Bell's palsy or facial asymmetry, which require careful assessment.
• Skin conditions in or near the treatment area, such as active infection, rosacea, or severe eczema.
• History of keloid scarring or unusual wound healing.
• Epilepsy or seizure history.
• Cardiovascular conditions that may be relevant to any medical procedure.

Even if you are unsure whether a condition is relevant, mention it. Your practitioner is trained to determine clinical relevance — you do not need to filter information in advance.

Certain medications and supplements can interact with botulinum toxin or increase the risk of bruising, swelling, or other complications. Your practitioner needs a full and honest picture of everything you are currently taking.

Medications to discuss include:

• Blood thinners and anticoagulants, such as warfarin, rivaroxaban, apixaban, or aspirin (when used for blood-thinning purposes). These increase bruising risk.
• Aminoglycoside antibiotics (such as gentamicin), which may potentiate the effects of botulinum toxin.
• Muscle relaxants and certain anaesthetic agents.
• Anti-seizure medications or treatments for neurological conditions.
• Immunosuppressant drugs, which may affect healing and infection risk.

Supplements to mention include:

• Fish oil and omega-3 supplements
• Vitamin E in high doses
• Garlic supplements
• Ginkgo biloba
• St John's Wort

These are commonly taken without much thought, but they can thin the blood and increase bruising. Your practitioner may advise pausing some supplements ahead of treatment, though this should only be done with appropriate guidance — never stop prescribed medications without consulting the prescribing doctor.

If you have had previous aesthetic treatments — at the same clinic or elsewhere — this information is highly relevant. Your practitioner will want to know:

• Previous botulinum toxin treatments: When, where, and by whom. What product was used, if known? Did you experience any side effects or unusual responses?
• Previous dermal filler treatments: Where fillers were placed, approximate timings, and the products used. This is important because fillers and anti-wrinkle injections are sometimes used in the same treatment plan, and knowledge of existing filler placement helps avoid complications.
• Any previous adverse reactions to injectable treatments.
• Surgical procedures in the face or head and neck area, which may affect anatomy and treatment planning.

Patients sometimes hesitate to mention previous treatments from other providers, perhaps feeling embarrassed or worried about judgement. There is no need for concern — this information is shared purely to inform safe, appropriate treatment planning. A guide to combining Profhilo with anti-wrinkle injections illustrates why comprehensive facial aesthetic planning matters.

Always tell your practitioner about any known allergies, including:

• Medication allergies, particularly to any previous injectable treatments or anaesthetics
• Latex allergy (relevant to the products and equipment used in clinic)
• Food allergies, particularly egg allergy, as some formulations use human albumin derived from blood products (your practitioner will clarify product-specific considerations)
• Skin sensitivities or reactions to topical products

If you have experienced anaphylaxis or a severe allergic reaction to anything in the past, this is especially important to disclose. Your practitioner should have appropriate emergency protocols in place, and knowing your allergy history helps them prepare accordingly.

Even if you do not think your allergy is relevant, mention it. Practitioners are trained to determine clinical significance — your role is simply to share what you know.

Anti-wrinkle injections using botulinum toxin are not considered appropriate during pregnancy or breastfeeding. This is a standard contraindication observed across UK aesthetic practice, in line with manufacturer guidance and clinical caution.

If there is any possibility that you could be pregnant, tell your practitioner before any aesthetic treatment begins. You will not be judged — this information simply ensures your safety and that of any developing pregnancy.

If you are trying to conceive, it is also worth mentioning, as your practitioner can factor this into their advice and timing recommendations. Family planning status helps inform longer-term treatment planning in a supportive and practical way.

To understand why anti-wrinkle injections are used and why patient information is so important to safe treatment, it helps to understand the underlying science.

The face contains dozens of muscles responsible for expressions — smiling, frowning, squinting, and concentrating. Over time, repeated contraction of these muscles causes the overlying skin to crease. Initially, these creases disappear when the face is at rest. Over years, however, the skin loses elasticity and collagen — the structural protein that keeps skin firm and resilient — making those lines more permanent.

Anti-wrinkle injections work on facial expression lines by temporarily interrupting the nerve signal that tells specific muscles to contract. When the targeted muscle cannot contract as strongly, the overlying skin has the opportunity to relax and smooth. This does not affect sensation, only muscle movement, and the effect is temporary — typically lasting several months before the nerve signal gradually recovers.

Because the toxin acts directly on the neuromuscular junction, understanding a patient's neuromuscular health is essential before treatment. This is why conditions affecting nerve-to-muscle communication, or medications that influence muscle function, are so clinically relevant to disclose.

Beyond medical history and medications, several lifestyle factors can influence treatment outcomes, recovery, and suitability. Be open about:

• Alcohol consumption: Heavy regular alcohol use affects skin health and bruising risk. Avoiding alcohol in the days immediately before treatment is often recommended.
• Smoking: Smoking impairs circulation and skin healing. It does not necessarily preclude treatment, but your practitioner may factor this into their assessment and advice.
• Sun exposure and skin condition: Significant sun damage or very thin, delicate skin may affect how treatment is planned.
• Exercise habits: High-intensity exercise immediately before or after treatment is generally advised against, as it can increase bruising and may theoretically affect early toxin distribution.
• Stress levels and sleep: These affect overall skin health and recovery capacity.
• Recent illness: If you are unwell with infection at the time of your appointment, most practitioners will recommend postponing treatment until you have recovered.

None of these factors are grounds for embarrassment or hesitation. Practitioners ask these questions in a professional, non-judgemental context to help deliver the safest and most appropriate care.

If you are experiencing visible facial lines or changes in your skin that concern you, a professional consultation can be a helpful starting point for understanding your options. You do not need to have already decided on a treatment to attend.

A consultation may be particularly useful if you:

• Have noticed dynamic lines appearing more prominently, such as frown lines or crow's feet
• Are uncertain whether anti-wrinkle injections would be appropriate for your skin concerns
• Have a complex medical history and want professional guidance on whether treatment is suitable for you
• Have had previous treatments and want a reassessment of your treatment plan
• Are interested in understanding the full range of options available, including non-injectable approaches

A consultation is an educational and exploratory process. It does not commit you to any treatment. A qualified practitioner can assess your individual anatomy, skin condition, and health history to discuss what — if anything — may be appropriate for you. You can find out more about the consultation process at Pantaleo Clinic to understand what to expect.

Understanding what anti-wrinkle injections can and cannot achieve is an essential part of informed consent and patient satisfaction.

Potential benefits, when treatment is deemed suitable, may include: A visible softening of dynamic facial lines A more rested or refreshed appearance A temporary effect that, for many patients, can be maintained with repeat treatment

Realistic limitations to understand: Results vary considerably between individuals. Factors including skin thickness, muscle strength, sun damage, and lifestyle all affect outcomes. Anti-wrinkle injections address dynamic lines caused by muscle movement. They do not address static lines (those present at rest in more mature skin) in the same way, and deeper structural concerns may require different approaches. The effect is temporary, typically lasting between three and six months, though this varies individually. There is no guarantee of a specific result. Practitioners can aim for a natural, softened outcome, but predicting exactly how an individual will respond is not possible. Some patients do not respond as strongly to botulinum toxin as others, and dosing adjustments may be needed over time.

Possible limitations and risks include localised bruising, swelling, headache, and — less commonly — temporary asymmetry or unintended effects in adjacent muscles. These are generally temporary and resolve without treatment, but should be discussed in full during your consultation.

Following anti-wrinkle injections, aftercare guidance from your practitioner should be followed carefully. General advice typically includes:

• Avoiding vigorous exercise after anti-wrinkle injections for 24–48 hours following treatment
• Avoiding lying down flat for several hours after the appointment
• Refraining from massaging or pressing the treated area
• Avoiding saunas, steam rooms, and excessive heat for at least 24–48 hours
• Not consuming alcohol immediately before or after treatment
• Using SPF daily: Sun protection is consistently important for skin health and longevity of results
• Maintaining good skin hydration: Using appropriate moisturisers helps support overall skin condition
• Attending follow-up as advised: Some practitioners offer a review appointment approximately two weeks after treatment to assess the outcome

Beyond specific post-treatment aftercare, maintaining general skin health supports the longevity of aesthetic results. A balanced diet, adequate hydration, quality sleep, and consistent use of SPF are evidence-informed habits that support skin resilience. You may also wish to explore skin rejuvenation treatments that complement anti-wrinkle injections for a more comprehensive approach to skin health.

• Before anti-wrinkle injections, always share your full medical history — including any neuromuscular conditions, bleeding disorders, or autoimmune conditions.
• Medications and supplements matter: Blood thinners, certain antibiotics, and common supplements can affect safety and results.
• Be honest about previous treatments, including fillers and any prior adverse reactions, to help your practitioner plan safely.
• Pregnancy and breastfeeding are contraindications — always disclose these.
• Results are temporary and vary between individuals — realistic expectations are essential to a positive experience.
• A thorough consultation is your safeguard: It is the foundation of safe, appropriate, and informed aesthetic treatment.

How far in advance should I tell my practitioner about my medications?

Ideally, you should disclose all medications and supplements at your initial consultation, which typically takes place before any treatment is administered. If you are booked in directly for treatment and have not had a separate consultation, inform the clinic in advance so that adequate time is allocated for a proper review. Never stop prescribed medications without consulting your prescribing doctor — your aesthetic practitioner can advise on how to proceed safely given your current medication regime.

Can I have anti-wrinkle injections if I take blood thinners?

This depends on the specific medication and your individual medical circumstances. Some people taking blood-thinning medications can proceed with treatment, while others may need medical clearance first. Bruising risk is generally higher with blood-thinning medications. Your practitioner will discuss the implications during your consultation and may liaise with your GP or specialist if necessary. Never adjust or pause prescribed blood-thinning medication without medical guidance.

What happens if I forget to mention something during the consultation?

If you remember something important after your consultation — or between consultations — contact the clinic before your treatment appointment. Your practitioner would always prefer to know relevant information, even at short notice. This might include a new medication, a recent illness, or a change in health status. Open communication protects your safety and allows your practitioner to make the most informed assessment possible.

Does my age affect whether anti-wrinkle injections are suitable for me?

Age is one factor considered during an individual assessment, but it is not the sole determinant of suitability. In the UK, treatment is not appropriate for those under 18 years of age. For adults, the relevance of age relates more to skin condition, degree of skin laxity, and the nature of the concerns being addressed. Anti-wrinkle injections tend to be most effective for dynamic lines, which can affect patients across a wide adult age range. Your practitioner will assess your individual anatomy and skin condition during consultation.

How soon before treatment should I stop drinking alcohol?

Most practitioners advise avoiding alcohol for at least 24–48 hours before anti-wrinkle injections. Alcohol acts as a vasodilator, which can increase the risk of bruising and swelling at injection sites. Following treatment, alcohol should similarly be avoided for at least 24 hours. If you have a social event or occasion coming up, discuss timing with your practitioner so that treatment can be planned appropriately.

What if I have had a previous bad reaction to anti-wrinkle injections elsewhere?

You must disclose this to your practitioner, including as much detail as possible about what occurred, when, which product was used (if known), and how the reaction was managed. Previous adverse reactions are clinically significant and will influence whether, how, and when treatment may be considered appropriate. This information will not be used to judge you — it is simply essential to safe clinical decision-making.

Knowing what to tell your practitioner before anti-wrinkle injections is one of the most important preparations you can make ahead of any aesthetic appointment. The information you share — from your medical history and current medications to your lifestyle habits and previous treatments — directly informs the safety and appropriateness of any treatment undertaken.

A thorough consultation is not a bureaucratic hurdle. It is the cornerstone of ethical, patient-centred aesthetic practice. Practitioners ask detailed questions because they are committed to your wellbeing — not simply to the delivery of a procedure.

If you are considering anti-wrinkle injections and have questions about what your consultation might involve, or what information you should prepare, seeking guidance from a qualified and experienced practitioner is always the right starting point.

Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.
