Botox for Tear Trough?

The tear trough area is the region under the eyes that can appear hollow and look like "bags or dark circles" under the eyes. A filler such as Juvederm or Restylane can be helpful at temporarily fillling in the depression and restoring a youthful look to the area, this can be done in the office. Botox weakens muscles, and has no role in the treatment of the tear trough area.

Botox is unlikely to help the tear trough area. Botox relaxes muscles, it does not fill in hollows. It could worsen ihollowness at the eye-cheek junction by relaxing the orbicularis muscle, causing further descent of the cheekpad.
Botox may be helpful for the procerus (rabbit's lines) next to the nasal bridge, but that doesn't seem to be your problem.
Usually, this area is addressed by a cheeklift procedure, possiblly with carefully, conservatively placed grafts. It is important not to treat this area agggressively, in my opionion, since it is so unforgiving. Often, fillers such as Prevelle or Restylane help greatly.

Many thanks for your question. 
The tear trough is a hollow area between the lower eyelid and where it meets the upper cheek. This gives the appearance of dark circles, under eye shadows or bags. The tear troughs can be treated by injecting dermal fillers into the area with immediate results. Botox is a muscle relaxant and will not improve the tear trough area. 
Please see a qualified medical practitioner with plenty of experience and you should be able to achieve excellent results very quickly. Good luck.
