Botox has made the ends of my eyebrows high and the start of my eyebrows really low, can this be correct?

Thank you for your question. Botox can definitely affect brow position and we often use this to our advantage to give a lateral brow lift. However, if treated incorrectly you can cause brow ptosis or drooping. It's difficult to determine without before and after photos but it sounds like you may have been treated too high in the central brow causing the medial brow to drop and not enough spaced enough on the side causing a "Spock" deformity. The touch up you received may help this but you need to give it at least 3-5 days to see the effect and I wouldn't recommend another touch up for at least a week. 
Ultimately, the botox will wear off in 3-4 months. If you're not satisfied with your initial treatment I would recommend that you seek out a core specialist (Dermatologist, Plastic or Facial Plastics) trained in injections for a full consultation. 

When brows are higher at the ends, giving a "Spock look" it can be corrected with small touch-ups, but since you just had a recent touch up one day ago, I would wait another 2 weeks before going back for further touch-up, it can take time to be fully active. Best, Dr P
