Is it possible to use Botox to prevent the smile from turning downwards without affecting upward smile?

As an expert injector, I have used Botox to improve the appearance of downturned mouth corners. If injected carefully by a Botox specialist, the treatment should not affect your ability to smile. However, improper injections can leave unsatisfactory results.

Yes, but you must see a physican that is VERY experienced with this area of the face. Just a small amount in the right muscle group works beautifully to turn that frown upside down.

Botox doesn't usually improve the downward corners of the mouth without wierd looking smile expressions but sometimes does ok. I don't think it is worth the risk. Fillers does a more consistent natural result to upturn the corners of the mouth and works everytime without looking wierd or abnormal. Sincerely,David Hansen,MD

Hi Jessica. Yes, this can be accomplished with Botox and Dysport. The key is not to overinject as to cause relaxation of the surrounding muscles that would control your smile when not at rest. The downside is that when you use a small amount of Dysport (Botox), the effects tend to wear off quickly so you end up having to come in more often than Dysport in other areas. View the pictures below where we used filler and Dysport to accomplish correction for a mouth frown.

botox is not approved for this use, but doctors have injected the muscle that pulls down on the corners of the mouth to help lift this region. It not uncommonly is done along with fillers, especially when the fillers don't improve the fold from the corner of the mouth down along the marionette line satisfactorily.
