Botox−肉毒注射

The effects generally last about four months, although individual results vary. Botox® Cosmetic should not be administered more frequently than every three months. Your practitioner will recommend follow-up timing based on your response.

The effect develops gradually rather than immediately, and timing can vary between patients and products. Your practitioner will explain when to assess your result and whether a follow-up appointment is appropriate.

The treatment plan is customized according to your facial movement, anatomy and preferred result. Dose and placement can be adjusted to retain an appropriate degree of movement, but outcomes vary and no specific result can be guaranteed.

All three are prescription botulinum toxin type A products, but they have different formulations and their units are not interchangeable. Your practitioner will recommend a product after considering the treatment area, anatomy, previous experience and clinical goals.

Possible reactions include injection-site pain, tenderness, redness, swelling or bruising, headache, eyelid changes and local muscle weakness. Rare but serious symptoms can include difficulty swallowing, speaking or breathing or weakness away from the injection area; seek immediate medical attention if these occur. Tell your practitioner about your medical conditions, medications, pregnancy or nursing status, allergies and any infection near a proposed injection site.
