Can Botox Lift Slightly Hooded Eyes?

I have used it for this purpose but it is very subtle and it works by throwing off the opposing muscle tensions around the eye,.Technically the eyebrows/eyelid are lifted by the forehead (frontalis) muscle but pulled down by the outer crow's feet muscles (orbicularis oculi). By weakening the latter, you allow the forehead to take over and exert an unopposed lifting effect on the eyebrow/eyelid

Botox, as well as other neuromodulators (Dysport, Xeomin), when injected into the crow's feet area, the tail of the eyebrow, and the glabella region softens the downward pull of the muscles in these regions, thereby granting a competitive advantage to the forehead muscles (the frontalis) to pull the brow upward slightly.

If appropriate, a small amount of filler material injected carefully under the eyebrows may further supplement the lift. My favorites for this purpose are Belotero Balance and Restylane L. 

Without a photograph, or better still the benefit of an actual examination, it is hard to actually say, but it is possible in this particular case that what I have called "The Ten Minute Eyelift" may be helpful for reducing the hooding should neuromodulators prove ineffective or only marginally so.

The Ten Minute Eyelift is a  minimally invasive procedure, performed under local anesthetic. With this technique thermal energy is delivered linearly along the junction of the lid and the brow. This results in immediate tightening and later to contraction of the skin upon healing, which in turn results in shrinkage of the hooded skin and better exposure of the upper lid.

Botox can temporarily lift the lateral portion (tail) of the brow by inhibiting one of the brow depressor muscles; this works well for patients with slight brow ptosis (droop).  However, if a patient has a significant amount of extra upper eyelid skin, the benefit offered by Botox in this region is less significant.
