Botulinum toxin procedures are known to be relatively safe, but there are two crucial points to confirm before treatment. First, the accuracy of the treatment area. If injected into the upper face near the ear, there is a risk of directly affecting facial nerves and causing side effects. Therefore, precise treatment by experienced medical staff is essential. Second, the use of appropriate dosage. Excessive dosage can cause symptoms similar to paralysis, and recently there has been a tendency to increase dosage due to reduced effectiveness, which requires caution. For safe and satisfactory results, be sure to confirm these two points.
