I don't remember having a problem like this before. I went snorkeling a week after getting the Botox for my forehad and today, after 20 hours, I still have a mark across my forehead. It isn't as bad as it was at first, but a mark for this long worries me. Is there anything I can do at this point? Do I have to wait & wait for it to go away? The mask wasn't abnormally tight, just regular. Sorry, I am on vacation & don't have a way to do a photo here.
