I had botox 3 days ago in my forehead and frownlines and during the same day I noticed the skin under my eyebrows looked like it had swelled and drooped downwards covering most of my eyelids. It feels and looks odd. I can't apply make up and eyeshadows like I used to. I contacted the doctor after only 1 day and he said it couldn't be the botox as it takes a few days to kick in and it must be fluid swelling or a slight allergic reaction but there's no improvement. How long do these effect last?
