Botox in depressor Septi for drooping nose, 1 day post, should I be worried about my mouth going weird? (photos)

It is likely that you will not have too much too worry about as it appears to have elevated the tip of your nose. Even if some botox does head to the upper lip region, it is a small quantity and any side effects will be short lived.

I have been using Botox for lifting drooping tips for nearly twenty years. In general it takes only a few units to achieve the lift and most often, as you correctly noted, it is achieved by injection centrally only. That being said, injection in the side locations that you indicated in the photo are not likely to lead to any real untoward reaction, given the relatively small doses you indicated that were used. Over the past fifteen years or so, I have combined the use of centrally injected Botox with the use of a filler with good lift, such as Restylane Lyft (which is my go-to for this in my NY office) and Hyabell Deep, which is my first choice in my Israel satellite facility, where a far greater number of regulatory agency approved fillers and volumizing fillers are available. Botox combined with filler in my experience tends to yield a synergistic effect that prolongs the four to six month Botox effect and the six to eight month filler effect to a year long effect when the two agents are used. Filler, like Botox is best injected centrally under the columella. Given what you have written, you would do well to be patient and wait two weeks before assessing the effects of your current treatment. Make sure that you are consulting with a board certified aesthetic physician. Best of luck.  

It can take up to 2 weeks for final results with Botox. I would wait a full 2 weeks before assessing results. However, try not to worry, it is unlikely to cause drooping based on your photos. Hope this helps.
