I'm 38, female, and I have a drooping eyebrow on one side of my face only. I lost a ton of weight and lots of volume in my face, but I don't know if the drooping is due to fat loss, muscle laxity, skin laxity or some combo. It seems to be the outer third that's drooping the most. So, will filler fix it if it's volume loss related? Or, do I need a brow lift? And where does Botox fit in to this? Why can Botox lift brows if drooping is caused by laxity?
