Botulinum Toxin
Injections
Botulinum toxin injections are prescription treatments that use carefully measured doses of a purified neurotoxin to temporarily reduce activity in selected muscles. By softening specific muscle movements, these treatments may help reduce the appearance of certain dynamic expression lines. They are medical procedures and require assessment and prescribing by an appropriately qualified practitioner.
Safety & Aftercare
Common effects and downtime
Important precautions
After treatment, it is common to notice: mild redness, swelling or tenderness at injection sites; small bruises; a feeling of tightness or heaviness in treated areas; temporary headache. These effects are usually mild and settle over a few days. You may be advised to avoid strenuous exercise or rubbing the area for a short period.
Botulinum toxin injections are not suitable for everyone, and extra caution or avoidance is needed in people who are pregnant, planning pregnancy or breastfeeding; have an active infection or significant inflammation at the planned injection sites; have certain neuromuscular conditions; are taking specific medicines that may interact with botulinum toxin; or have had previous unusual or allergic-type reactions to botulinum toxin products.
Possible side effects
When to seek urgent medical review
Treatments carry potential risks including more noticeable bruising, temporary asymmetry, or eyelid/brow droop when treating the upper face. Lower face treatments may affect lip movement. Your doctor will discuss specific risks tailored to your plan.
Difficulty breathing, speaking or swallowing; widespread or unusual muscle weakness; severe allergic-type symptoms (such as swelling of the face, lips or tongue, or difficulty breathing); or significant visual changes, severe headache or other worrying neurological symptoms need prompt emergency medical care.
Common Questions
Am I suitable for botulinum toxin injections?
Suitability depends on your facial anatomy, muscle pattern, skin, medical history and current treatments. Botulinum toxin is not appropriate for everyone, and some concerns are better managed with other approaches. A consultation with a qualified doctor is needed to decide whether this treatment is suitable for you.
Do botulinum toxin injections hurt?
Most people describe brief stinging or pressure with each injection. The needles used are very fine, and any discomfort is usually short‑lived. Your doctor will explain what you may feel and how any sensitivity can be managed.
When will I notice results and how long do they last?
Changes usually begin to appear after a few days, with the full effect developing over about 1–2 weeks. The visible effect commonly lasts around 3–4 months before gradually wearing off, but this varies between individuals and treatment areas. No specific result or duration can be guaranteed.
Is there any downtime?
Most people can return to light daily activities soon after treatment. Mild redness, swelling or bruising can occur and may be visible for a few days. You may prefer to avoid important social events until these effects settle. Your individual recovery may differ.
Can botulinum toxin be combined with other treatments?
Botulinum toxin injections may sometimes be combined with other aesthetic treatments, but timing and combinations need to be planned carefully. Your doctor will review your current and past treatments and advise on a safe, personalised plan.

What is botulinum toxin?
Botulinum toxin is a purified protein that acts at the junction between nerves and muscles. When injected in small, targeted amounts, it can temporarily reduce the ability of selected muscles to contract as strongly. In aesthetic practice, this effect is used to soften the appearance of lines that are formed or worsened by repeated facial expressions, such as frowning or squinting.
How does it work on expression lines?
Many facial lines are dynamic, meaning they appear or deepen when we move our muscles to frown, raise our brows or smile. By reducing the activity of specific muscles, botulinum toxin can lessen the movement that contributes to these lines. Over time, this may help treated areas look smoother at rest. The aim is usually to soften lines while keeping natural expression, not to “freeze” the face.
Concerns it may be considered for
Botulinum toxin injections may be discussed as an option for: Frown lines between the eyebrows; Horizontal forehead lines; Crow’s feet around the eyes. In some cases, it may also be considered for other carefully selected areas. Suitability depends on your facial anatomy, muscle pattern, skin quality, medical history and treatment goals. A detailed, face‑to‑face assessment is essential before deciding if this treatment is appropriate for you.
Consultation and preparation
Before treatment, your doctor will: take a full medical history, including any neuromuscular conditions and medications; examine your facial anatomy, muscle movement and skin; discuss your concerns, goals and previous treatments; explain realistic expectations, potential risks and alternatives. You may be advised to avoid alcohol and blood‑thinning medicines, avoid scheduling treatment before important events, and arrive with clean skin.
