My right eyebrow is lower than my left eyebrow & it has more eyelid skin. What can be done to fix it? What causes it? (photo)

You do have eyebrow asymmetry which is very common. You also have a droop or ptosis of your right upper eyelid. You should seek a consultation with an eyelid plastic surgeon. Make sure that they recognize that you have an eyelid droop and that they are experienced in ptosis repair. If they are not seek a second or third opinion.

You also have a ptosis of the right upper eyelid.  Some of this may be due to the heaviness in the upper eyelid on this side from the low bro weighing down the lid.  You should see an oculoplastic surgeon to determine if you have a true ptosis or pseudoptosis.  When you are able to afford it, you can have the right brow lifted to make your look more symmetrical.
