Common side effects of preventative Botox include temporary injection site reactions like bruising, swelling, and tenderness. Most patients in Thailand experience mild symptoms such as headaches or a heavy sensation in the brow. These typically resolve within 24 to 48 hours without medical intervention.
- Injection site reactions: Tiny bumps, stinging, or bruising occur at the needle entry points.
- Headache: Temporary tension or aching is common during the first two days.
- Facial asymmetry: Improper placement can cause slightly uneven results or droopy eyelids.
- Frozen expression: Over-treatment or high doses can restrict natural facial movement and expressions.
Bookimed Expert Insight: Thai clinics like Plenary Wellness and Wansiri Hospital frequently use Aestox. This premium Korean brand is known for providing natural-looking results. High-volume centres in Bangkok serve over 1,000 patients annually. They use conservative dosing to avoid the heavy, frozen look sometimes linked to preventative treatments. Focusing on smaller, 50-unit sessions rather than large doses significantly reduces the risk of brow drooping.
Patient Consensus: Patients in Thailand recommend planning for minor bruising or swelling that settles quickly. Starting with lower doses helps prevent a frozen appearance. Patients also suggest emphasising subtle, natural outcomes during consultations.
