Doctor-led botulinum toxin treatments for facial lines, jaw clenching, neck contouring and excessive sweating at Hazel Clinic, Blackrock, Dublin. by Dr. Susana Fontana

Facial expressions are an important part of how we communicate, but repeated muscle movements can gradually create lines that remain visible even when the face is at rest.

Anti-wrinkle injections can help soften these lines while preserving natural facial expression when the treatment is carefully planned and appropriately administered.

At Hazel Clinic in Blackrock, Dublin, Dr Susana Fontana provides personalised anti-wrinkle treatments using botulinum toxin. Her approach focuses on understanding facial anatomy, assessing individual muscle movement and selecting an appropriate treatment plan for each patient.

The aim is not to change how you look or eliminate every line. It is to soften unwanted wrinkles, maintain facial balance and achieve a refreshed appearance without an unnecessarily restricted or frozen expression.

Botulinum toxin also has established medical applications beyond facial aesthetics. Depending on the clinical indication, it may be used to manage excessive sweating, certain forms of jaw muscle overactivity and selected other muscle-related conditions.

Every treatment at Hazel Clinic begins with an individual medical assessment to determine suitability, discuss realistic expectations and explain the potential benefits and risks.

What Are Anti-Wrinkle Injections?

Anti-wrinkle injections use botulinum toxin, a prescription-only medicine that temporarily reduces the activity of selected muscles.

The medicine acts on the communication between nerves and muscles, reducing the release of acetylcholine and limiting muscle contraction in the treated area.

In aesthetic medicine, this effect can soften dynamic wrinkles: lines that develop through repeated facial expressions such as frowning, raising the eyebrows or smiling.

The treatment does not fill wrinkles or add volume. Instead, it temporarily reduces the muscle activity contributing to their appearance.

Botulinum toxin can also be used for certain medical indications, including primary axillary hyperhidrosis and specific muscle overactivity disorders, when clinically appropriate.

The dose, injection sites and treatment plan depend on the indication, the patient’s anatomy and their medical history.

Anti-Wrinkle Injections at Hazel Clinic, Blackrock, Dublin

Hazel Clinic is a doctor-led dermatology and aesthetic medicine clinic founded and directed by Dr Susana Fontana.

Our approach to anti-wrinkle injections is based on medical assessment, individual treatment planning and attention to natural facial movement.

Rather than automatically treating the same areas in every patient, Dr Fontana assesses how your facial muscles work together, where lines appear and whether treatment is likely to achieve your goals.

Some patients want to soften prominent forehead lines. Others are concerned about frown lines, crow’s feet or the appearance of tension around the eyes.

For other patients, the concern may be functional rather than purely aesthetic, such as jaw clenching or excessive sweating.

The appropriate approach depends on the individual indication and whether treatment is medically suitable.

We prioritise balanced results and avoid unnecessary treatment. If a procedure is unlikely to offer meaningful benefit, this should form part of the discussion before you make a decision.

Meet Dr Susana Fontana

Dr Susana Fontana is the founder and Medical Director of Hazel Clinic in Blackrock, Dublin.

Her medical background includes an MD, GPST and MICGP qualifications, postgraduate training in Aesthetic Medicine and Nutrition, and a Diploma in Dermatology.

Her experience in general practice, dermatology and aesthetic medicine informs a medically grounded approach to injectable treatments.

Understanding facial anatomy, muscle function, skin characteristics and the patient’s medical history is essential when planning botulinum toxin treatment.

This is particularly important when treating areas such as the forehead, where muscle activity can affect eyebrow position, or the lower face and neck, where different muscles contribute to movement and contour.

For medical indications, a careful assessment is equally important to establish whether botulinum toxin is appropriate and whether additional medical evaluation is required.

At Hazel Clinic, the focus is on selecting the right treatment for the individual rather than applying a standardised approach to every face.

What Areas Can Be Treated with Anti-Wrinkle Injections?

The most suitable treatment areas depend on your facial anatomy, muscle activity, medical history and goals.

Forehead Lines

Horizontal forehead lines commonly become more visible when raising the eyebrows.

Carefully planned treatment can soften these lines while preserving appropriate eyebrow movement and facial expression.

The forehead requires particular attention because excessive weakening of certain muscles can affect eyebrow position or create an unwanted heavy sensation.

Dr Fontana assesses forehead movement and surrounding muscles before determining whether treatment is appropriate.

Frown Lines

Frown lines develop between the eyebrows through the activity of muscles involved in drawing the eyebrows together.

These lines can sometimes create an appearance of concentration, tension or anger, even when a person is relaxed.

Botulinum toxin can reduce the muscle activity contributing to these lines, producing a softer appearance.

The treatment plan is tailored to the strength and pattern of muscle movement rather than relying on the same dose for everyone.

Crow’s Feet

Crow’s feet are the fine lines that appear at the outer corners of the eyes when smiling or squinting.

Botulinum toxin can soften these dynamic lines by reducing activity in the muscles around the eyes.

The goal is to preserve natural expression while reducing the prominence of unwanted lines. The appropriate treatment depends on the patient’s anatomy and the degree of movement in the area.

Bunny Lines

Bunny lines are small wrinkles that appear along the sides of the nose when certain facial expressions are made.

In selected patients, carefully targeted treatment may soften these lines. However, the surrounding muscles also contribute to normal facial movement, so treatment requires an individual assessment.

Gummy Smile

A gummy smile occurs when a relatively large amount of gum tissue becomes visible above the upper teeth when smiling.

In selected cases, excessive activity in muscles that elevate the upper lip may contribute to this appearance.

Botulinum toxin may help reduce the elevation of the upper lip in suitable patients. Results depend on the underlying cause and are temporary.

A clinical assessment is necessary to establish whether muscle activity is the main factor and whether treatment is likely to help.

Lip Flip

A lip flip involves carefully placed botulinum toxin injections into selected muscles around the upper lip.

By temporarily reducing activity in these muscles, the treatment may allow the upper lip to appear slightly more turned out when smiling.

It does not add volume in the way dermal fillers do. The result is generally subtle and temporary, and the treatment may not be appropriate for people who rely on strong lip movement for certain activities.

Masseter Treatment for Jaw Clenching and Teeth Grinding

The masseter muscles are located at the sides of the jaw and play an important role in chewing.

In selected patients, botulinum toxin injections into these muscles may help reduce excessive muscle activity associated with jaw clenching or teeth grinding.

Treatment may also reduce the prominence of enlarged masseter muscles, which can contribute to a wider or more square-looking lower face.

For aesthetic purposes, this is sometimes referred to as facial slimming.

However, teeth grinding and jaw pain can have several causes. Botulinum toxin does not correct every cause of bruxism and does not replace a dental assessment when one is indicated.

Potential benefits, limitations and risks should be discussed before treatment, including possible changes in chewing strength and the effect of repeated treatment on the jaw muscles.

Nefertiti Neck Lift

The Nefertiti neck lift is a non-surgical treatment that uses botulinum toxin in selected areas of the lower face and neck.

It targets specific muscle activity that can contribute to downward pull around the jawline and visible vertical neck bands.

By temporarily reducing the activity of selected muscles, treatment may create a more defined-looking jawline and a smoother appearance of certain neck bands.

The treatment may be suitable for some patients who want a subtle improvement in neck contour and a more elongated-looking profile without surgery.

However, it is important to understand its limitations. The Nefertiti neck lift does not remove excess skin, restore lost skin elasticity or reliably correct significant skin laxity.

The degree of improvement depends on anatomy, muscle activity and the condition of the skin. Dr Fontana will assess whether the treatment is likely to achieve a meaningful result or whether another approach would be more appropriate.

Hyperhidrosis: Excessive Sweating

Hyperhidrosis refers to sweating that is excessive in relation to the body’s normal temperature regulation needs.

It can affect the underarms, palms of the hands and other areas, sometimes interfering with work, social activities and everyday comfort.

Botulinum toxin can help manage certain forms of hyperhidrosis by temporarily blocking the nerve signals that stimulate sweat glands in the treated area.

At Hazel Clinic, treatment may be considered for suitable patients experiencing excessive underarm sweating or sweating of the palms, following an appropriate medical assessment.

The treatment reduces sweating in the targeted area rather than treating every possible cause of excessive sweating.

For palm treatment, temporary weakness of nearby hand muscles is a potential consideration and should be discussed beforehand.

The duration of benefit varies according to the area treated and the individual response.

Other Medical Applications

Botulinum toxin is also used in medicine for certain diagnosed conditions involving excessive muscle activity.

Depending on the diagnosis, formulation and clinical setting, medical applications can include selected movement disorders, spasticity and other specific neuromuscular conditions.

Some patients may ask about treatment for persistent neck or shoulder tension, upper back muscle overactivity or symptoms following spinal surgery.

These presentations require an individual medical assessment. Botulinum toxin is not a general treatment for back pain, postural problems, scoliosis or muscle atrophy, and it is not appropriate for every muscle-related complaint.

Where treatment for a complex neurological or musculoskeletal condition is being considered, the decision should be based on the specific diagnosis, relevant evidence and the appropriate specialist’s assessment.

Medical applications at Hazel Clinic are considered only where appropriate to the clinical indication and the services provided.

What to Expect During Your Appointment

Your appointment begins with a consultation and assessment to understand your concerns and determine whether botulinum toxin is suitable.

1. Medical and Facial Assessment

Dr Fontana will discuss your treatment goals, medical history, current medication and any previous experience with anti-wrinkle injections.

For facial treatments, she will assess muscle movement, the location of dynamic lines and the relationship between different areas of the face.

For medical indications, the assessment will focus on the relevant symptoms, the likely cause and whether further investigation or another form of treatment is needed.

2. Personalised Treatment Planning

Once suitability has been established, Dr Fontana will explain the proposed treatment, expected results, limitations and potential risks.

The areas treated and the amount of medicine used depend on the clinical assessment. Not everyone requires treatment in multiple areas, and additional injections are not automatically necessary for a good result.

You will have an opportunity to ask questions before deciding whether to proceed.

3. Treatment

The skin is prepared, and small amounts of botulinum toxin are injected into selected muscles using a fine needle.

The procedure usually takes around 20 minutes, depending on the number of areas being treated.

Discomfort is generally mild and brief. Numbing cream is not usually necessary for standard facial treatment, although comfort measures can be discussed where appropriate.

4. Aftercare and Review

Most patients can return to their normal daily activities shortly after treatment.

Small injection marks or temporary raised bumps may be visible immediately after the procedure and usually settle relatively quickly. Minor redness, swelling or bruising can also occur.

Dr Fontana will provide individual aftercare instructions and advise you when to expect the result to develop.

For new aesthetic patients, a review may be arranged around two weeks after treatment, when the effect can be assessed. Any adjustment is based on the clinical findings and must be appropriate to the medicine and treatment performed.

When Will You See Results?

Botulinum toxin does not usually produce its full effect immediately.

Initial changes may become noticeable within three to seven days, with the result generally developing further over approximately two weeks.

The timing varies according to the area treated, the formulation used and individual factors.

For aesthetic treatments, the aim is to soften dynamic lines while preserving an appropriate degree of natural movement.

For medical treatments, the response depends on the condition being treated and may require a different review schedule.

A follow-up assessment can help determine how well the treatment has worked and whether any further management is appropriate.

How Long Do Anti-Wrinkle Injections Last?

For many aesthetic treatments, the effects of botulinum toxin last approximately three to four months, although some patients experience shorter or longer periods of benefit.

Duration depends on the area treated, the dose, muscle strength, the formulation used and individual response.

Medical treatments for excessive sweating or other indications can have different durations of effect.

Treatment should not be repeated automatically at fixed intervals without considering the clinical response, the medicine’s prescribing information and the patient’s individual needs.

Dr Fontana can advise on appropriate review and retreatment timing.

Who Is Suitable for Anti-Wrinkle Injections?

Botulinum toxin is not suitable for everyone.

A medical assessment is important before treatment, particularly for patients with underlying health conditions or those taking medication that may affect neuromuscular function.

Treatment is generally avoided during pregnancy and breastfeeding because of insufficient safety data.

It should not be administered to patients with an active infection at the proposed injection site. Certain neurological or neuromuscular conditions, previous allergic reactions to the medicine or its ingredients, and some medications may also make treatment unsuitable or require particular caution.

If you are feeling unwell or have recently experienced an acute illness, your appointment may need to be postponed.

You should disclose all relevant medical conditions, allergies, medications and supplements during your consultation.

The final decision about suitability is made by the prescribing medical practitioner after considering the individual circumstances.

Aftercare: What Should You Expect?

Recovery after standard facial anti-wrinkle injections is generally minimal.

You may notice small raised areas at the injection sites immediately after treatment. These usually settle within a short period, although bruising, redness, tenderness or swelling can occur.

You should follow the aftercare instructions provided by your medical practitioner. These may include avoiding rubbing or massaging the treated areas for the period advised and following guidance about strenuous exercise or other activities immediately after treatment.

There is generally no need for significant social downtime, although this cannot be guaranteed.

If you experience unexpected or concerning symptoms after treatment, contact your treating clinician. Difficulty swallowing, speaking or breathing, or generalised weakness requires urgent medical assessment.

Why Choose Hazel Clinic for Anti-Wrinkle Injections in Dublin?

Choosing a medical practitioner for injectable treatment is important because botulinum toxin affects muscle function and must be prescribed and administered appropriately.

At Hazel Clinic, treatment is provided within a doctor-led clinical setting in Blackrock, Dublin.

Dr Susana Fontana combines medical training with postgraduate qualifications in aesthetic medicine and dermatology. Her approach emphasises individual assessment, appropriate dosing and an understanding of how different facial muscles interact.

We aim for results that look considered rather than obvious.

That means taking account of your natural expression, explaining what treatment can realistically achieve and avoiding unnecessary injections.

We also recognise that not every concern requires an injectable procedure. Depending on the presentation, another treatment or no treatment at all may be the more appropriate recommendation.

For medical indications, a clear understanding of the underlying problem is equally important. Treatment should be based on a suitable clinical indication rather than the assumption that botulinum toxin can resolve every muscle-related concern.

Frequently Asked Questions About Anti-Wrinkle Injections

Are anti-wrinkle injections safe when administered by a doctor?

Botulinum toxin has established medical uses, but, like any prescription medicine, it carries potential risks and is not suitable for everyone.

At Hazel Clinic, treatment is prescribed and administered by Dr Susana Fontana following an individual assessment. The consultation considers your medical history, treatment goals, suitability and the potential benefits and risks.

Correct assessment and administration help manage risk, but they cannot eliminate every possible complication.

How much do anti-wrinkle injections cost in Dublin?

At Hazel Clinic in Blackrock, Dublin, aesthetic anti-wrinkle injections start from €275 for one area, €300 for two areas and €375 for three areas. Additional areas start from €50 each. Specific treatments, including masseter injections, the Nefertiti neck lift and hyperhidrosis treatment, have separate starting prices.

The final cost depends on the treatment required and your clinical assessment.

Will I look frozen or unnatural?

The aim at Hazel Clinic is to soften unwanted lines while preserving natural facial expression.

Treatment is planned according to your facial anatomy and muscle movement, rather than applying the same dose to everyone.

However, the result depends on individual factors, and excessive muscle weakness can occur. Dr Fontana will discuss the intended outcome and relevant risks before proceeding.

How long do anti-wrinkle injections last?

For many aesthetic indications, the effect lasts approximately three to four months. The duration varies between individuals and treatment areas. Some medical applications have different durations of benefit.

When will I see results?

Initial changes often appear within three to seven days, with the result developing further over approximately two weeks. Your doctor can advise when the outcome should be assessed for your particular treatment.

Can anti-wrinkle injections prevent wrinkles?

Reducing repeated muscle contraction may help limit the development or deepening of certain dynamic lines. However, injections cannot prevent all wrinkles or stop the natural ageing process.

Sun exposure, skin quality, genetics and other factors also influence how lines develop over time.

What is the difference between Botox and anti-wrinkle injections?

Botox is a well-known brand of botulinum toxin. Anti-wrinkle injections is a broader term used to describe treatments that temporarily reduce selected muscle activity to soften dynamic facial lines.

Different botulinum toxin products have their own prescribing information and dosing requirements and should not be treated as interchangeable on a unit-for-unit basis.

Can botulinum toxin help with teeth grinding and jaw clenching?

In selected patients, injections into the masseter muscles may reduce muscle activity associated with clenching or grinding.

However, bruxism can have several contributing factors, and treatment does not replace dental assessment or other appropriate management. Potential effects on chewing strength and the jaw muscles should be discussed before treatment.

What is a Nefertiti neck lift?

A Nefertiti neck lift uses botulinum toxin in selected muscles around the lower face and neck.

It may help soften certain neck bands and reduce the downward pull of specific muscles, producing a more defined-looking jawline in suitable patients.

It does not remove excess skin or correct significant skin laxity. The degree of improvement depends on anatomy and muscle activity.

Can Botox treat excessive sweating?

Botulinum toxin can help manage certain forms of hyperhidrosis by reducing nerve signals that stimulate sweat glands.

Treatment may be considered for excessive underarm sweating and, in selected patients, sweating of the palms. The suitability, expected duration and potential side effects depend on the area treated and the individual.

Can botulinum toxin treat neck, shoulder or back muscle problems?

Botulinum toxin has medical applications for certain diagnosed conditions involving excessive muscle activity. However, neck, shoulder and back symptoms can have many causes.

It is not a general treatment for muscle pain, scoliosis, poor posture or muscle atrophy. A medical assessment is needed to establish the diagnosis and determine whether treatment is appropriate.

Can I have anti-wrinkle injections if I am pregnant or breastfeeding?

Treatment is generally avoided during pregnancy and breastfeeding because adequate safety data are not available. Discuss your circumstances with your medical practitioner before considering treatment.

Is there any downtime after anti-wrinkle injections?

Most patients return to normal daily activities shortly after treatment. Small injection marks, redness or swelling may occur, and bruising is possible.

Your clinician will provide aftercare advice and explain when to seek medical attention if unexpected symptoms develop.
