What is the downside of Botox?
Botox is a widely used cosmetic treatment with a strong safety profile, but like any injectable, it can cause temporary and occasionally more uncommon side effects. Most are mild and short-lived, especially when treatment is carried out by an experienced professional.
Common and temporary side effects
These usually settle within hours or a couple of days:
- Redness, swelling or slight bruising at the injection point
- Mild discomfort or sensitivity
- Headache
- Flu-like feeling for a short period
Aesthetic considerations
These effects are uncommon and can vary depending on individual muscle strength, sensitivity, and how your face responds to treatment:
- A temporary “heavy” feeling or reduced movement in the treated area
- Mild eyelid or brow drooping in rare cases if the product affects nearby muscles
We always start conservatively for first-time patients so we can understand your unique muscle pattern and adjust your dose over time to ensure the most natural result.
Rare or less common side effects
Rare but possible:
- Allergic reaction
- Nausea or general unwell feeling
- Difficulty swallowing or speaking (very rare)
- Infection at the injection site
How to minimise risks
Botox is extremely safe when performed correctly. To reduce the likelihood of side effects:
- Choose a medically qualified, experienced injector
- Avoid rubbing the area for 24 hours
- Follow all aftercare guidance
- Discuss your medical history at consultation
