Anti-wrinkle injections 2.5 weeks ago, one brow now sits slightly higher — wait it out or go back?

First time having anti-wrinkle injections (forehead + frown lines), done about two and a half weeks ago at a proper clinic with a nurse prescriber, patch test, consultation, the whole thing done by the book.

Results are honestly 90% great, forehead is smooth, frown line basically gone. BUT my right eyebrow now sits noticeably higher than the left when my face is relaxed. Not full on Spock but definitely visible in photos, my sister clocked it immediately which is how I know it's not in my head.

The clinic said at my appointment that they do a free 2-3 week review and to come back if anything needs adjusting. My worry is: if they add more product to even it out, does that mean more product wearing off unevenly later? And is 2.5 weeks still early enough that it might settle on its own, or is what I see now what I've got for the next 3 months?

Anyone had the uneven brow thing first time round? Did the top-up fix it properly or just create a different problem? Trying to decide whether to book the review or just fringe it out until November lol

Also side question, is it normal that the clinic asks for photos before booking the review slot?
