Can Botox help in preventing the corners of the mouth to turn down? Or can it improve this problem?
Yes – it can if it’s injected into a muscle in the area just lateral to the chin in exactly the right spot. There is a muscle called the depressor anguli ori (DAO) that pulls the corner of the mouth down and, if it is weakened just the right amount, the corner of the mouth will pull up a little.
PLEASE only let doctors/nurses who are experts do this. If it’s done incorrectly you may look like you’ve had a stroke, have a smile that looks really weird or worst case, even drool a little.
The lower facial muscles are very complicated. This is why we can make sooooooo many different expressions with our mouths, including all those funny ones that get Snapchatted, etc.
Hope this helps, Dr. I
