I'm curious about reviews regarding Botox for the corners of the mouth.

I am considering Botox because I am often misunderstood as looking sullen or depressed due to the drooping corners of my mouth. The asymmetry is particularly severe, with one corner of my mouth lifting less than the other when I speak or take photos, so it bothers me a lot every time I look in the mirror.

I found reviews online stating that receiving a smile Botox injection to tighten the depressor muscles of the corners of the mouth causes the corners to lift slightly even when at rest, making the overall impression much softer. Since the procedure involves the mouth area, I am concerned about potential side effects that may interfere with daily life, such as difficulty eating or drooling. I would appreciate it if those who have received Botox to correct lip asymmetry or sagging facial features could share their honest before-and-after satisfaction results and approximate cost information.
