Permanent Ptosis Following Botox? (photo)

Hi Anon.  Botox does not cause permanent ptosis because the effects of Botox are not permanent.  It does appear that you have some heaviness in the left lid, but if this area looks like this all the time, it is just part of who you are.  Botox can make it better or worse, but it cannot permanently change your look.  

If the condition came on suddently, then you may want to check with a neurologist.  Otherwise, we would actually suggest using a Botox browlift to help with the issue.  

My guess is that you have natural asymmetry of your brow position. As you age, this may become more obvious. For patients with any hint of brow ptosis, I tpically treat the 'brow depressor' muscles with Botox (glabella and lateral orbicularis muscles) and leave the frontalis muscles alone (brow elevators).
