Will Botox Above my Upper Lip Stop It from Excessive Sweating?

I have injected botox in the upper lip, and even the nose for excessive sweating. I agree that you need to use a very small amount (3-5 units total depending on your lip size, spread out in .5 unit injections). It probably will affect the muscles of the upper lip, and you may notice that your lip feels "clumsy". By this, I mean that you may have difficulty with drinking from straws and puckering. However, I think it could be worth it to try. The effects will wear off, so if you really dislike the feeling, it will get better. The other interesting option would be to consider treatment with Ulthera. It would be off-label, but there are good studies showing that this ultrasonic device works well to decrease sweating in the armpits. I would recommend going to someone with lots of experience for an in-person consult. Good luck.

Your experience with Botox and underarm sweat and for your hair line is to be expected - Many happy patients are surprised at how effective and liberating a reduction in their sweat to these areas can be. On the upper lip, Botox will reduce the sweating but unfortunately this will also reduce your lip movement. Very small dosing could achieve an an acceptable balance of improvement but this would likely only last a short period of time. Microneedling RF treatments done at the correct depth could reduce the sweat gland activity without the risks of reducing movement. You could also try OTC antiperspirant every other day on this area :)

Be careful! Botox can reduce the sweating but may cause difficulty with smiling, eating and speaking. It could be difficult to brush your upper teeth because the upper lip could droop over the teeth and you might have to hold up the lip with one hand while brushing the teeth with the other. The very few units that could be injected without altering the lip muscle adversely may be too little to reduce the sweating satisfactorily. If a droop occurs, you might have to wait for as much as three to four months for the muscle to regain activity.
