More serious symptoms associated with Botox injections–such as eyelid droop–are rare. More common side effects may include temporary bruising, swelling, or tenderness in the injected area. These injection site reactions should subside within a few days of treatment. Each patient is assessed for their specific risk depending on their treatment plan.  Consulting with a qualified, experienced practitioner significantly decreases the risk of such complications.   Dr. Yamasaki takes special care to ensure a safe and effective procedure for all her patients.  She provides instructions before and after each procedure.
