The full effects of Botox does take at least two weeks to manifest, so yes you may see more drooping but it will start getting better in a month or so in most cases. Full return to normal may take three to four months.
Thank you for your question. Unfortunately the full effects of botox can take up to 2 weeks so yes the drop may get worse. If the drop is from the forehead being injected you will just need to wait for it to bounce back. It could take 1 month. I would let the injector know to prevent this from happening again.Good luck
