How long does it take for botox to attach to the nerve?

Thank you for asking. Treatments like Botox and Dysport setup mostly in hours but there may be ongoing effects a bit longer. I advise patients to avoid significant rubbing, massage and similar positional activities for a day or so. The full onset of these products can be seen a week or so out from the treatment. It is quite uncommon to have a dropped position of an eyebrow or eyelid if the product is placed properly and the product did not drift or move outside the treated area. There may be treatment options if an eyelid or brow is dropped. Talk with your doctor about possible options. Best wishes

it can take a full week to get effect of Botox. It can migrate if massaged or you work out which is why I recommend no work out for 24 hours. Talk to your plastic surgeon if you're experiencing eyelid droop.
