The main possible problem comes if Botox is injected by an inexperienced injector. If Botox is injected into an incorrect muscle, it can cause issues such as a droopy eyelid. That’s why it’s very important to have Botox injected by an expert in facial anatomy who has extensive experience with Botox, such as Dr. Berardi.
Otherwise, the main issues after Botox injections are slight swelling and redness at the injection sites. These usually resolve themselves in a day.
