I am concerned about the asymmetry between my lip fillers and lip corner Botox.. (Progress after re-treatment)

On March 13th, I got lip fillers and lip corner Botox for the first time.

However, starting from the second day after the procedure, asymmetry developed in my lower lip, and the left side (right in the photo) sagged noticeably further down.

Eventually, I revisited the hospital on March 19th for a consultation and received additional Botox injections in the area near the jaw on the opposite side (the side that went down less).

But there has been almost no change even as of today (March 22nd), so I'm really stressed out...

Do I need more time to see the effects after getting the additional Botox? Or is this because the Botox was administered incorrectly? If anyone has had a similar experience, please give me some advice.
