The following would suggest you need a browlift: if there is "hooding" of the upper lid that extends past the end of the eye towards the crow’s feet; if when you pull up on the eyebrow to the height you think looks right your eye lid has no more hooding or bulging fat; if your brow has lost its arch; if your brow is within your eye socket. But if your eyebrow has a nice arch or is at the height that you want it to be, then an upper blepharoplasty may be what you need. But these distinctions are often subtle and it is hard for a patient to know for sure without seeing a plastic surgeon…and even plastic surgeons will have different opinions about which procedure might look the best on a particular patient.
