Can ultherapy lift brows straight up or only up towards the sides?

It's a little curious that Botox did not work for you. If you can purposefully raise your brows and lower them, you "should" be able to get some lift from Botox or one of the other neuromodulators Xeomin or Dysport. It is not possible to assess a possible reason without actually seeing your facial muscles in action.Ultherapy will tighten the tissue somewhat but it may not deliver what you hope for unless there is some treatable level of laxity in your skin. You might want to investigate the "tox" option a little further.

Ultherapy's protocol had been designed to treat the outer forehead but I have been able to use the ultherapy as an off-label indication by treating the middle of the forehead, taking care not to irritate the sensory nerves over the middle of the eyebrow. This has helped provide extra lift compared to only treating the outer eyebrow areas.

When you do ultherapy in the forehead, the best lift will be over the lateral portion of the brow which is where it is most mobile.  As you move more centrally in the forehead, there will be less lifting.  To get up the whole brow you would need to do some sort of surgical lift.      

Ultherapy does a wonderful job in lifting the brows and the energy lines are directed mid brow and outward, laterally, causing the outer brows to lift and open the eyes a bit. It will give you a very natural look.Read the Ultherapy ebook provided on the link below.

Ultherapy works quite well as a non-surgical brow lift by lifting both up and out for a very natural result.
