Smile is ruined from Botox! What went wrong? (photos)

It appears that your asymmetric smile may be due to having Botox placed in the depressor anguli oris, or possibly the depressor labii inferioris, muscle on one side but not the other.This muscle pulls down on the lower lip. By temporarily paralyzing this muscle with Botox, the lower lip on the affected side will no longer move down.If you wish to improve your smile to a  more symmetric one, you may have Botox placed on the non-affected side's depressor anguli oris/depressor labii inferioris.The other option of course is to wait until the Botox wears off over the next 2-3 months. Thanks for sharing. 

Botox injections can be used around the mouth to lift the corners of the mouth, decrease chin dimpling and expression, reduce gummy smiles and to halt vertical lip lines.  However, it is best done by an expert injector because injections of too high a dosage or wrong location can lead to negative results such as you are experiencing.  The injections have effected your depressor labii inferioris muscle which lowers and everts the bottom lip.   Thankfully, it will fade more quickly than other areas of the face; however, you could consider treating the opposite side to create symmetry for the time being.  Make sure to seek out an expert in facial injectables if you want this corrected and for all treatments in the future.

I'm sorry you are unhappy with your Botox treatment. Unfortunately the placement of the Botox is responsible for the result. The effect is temporary and will gradually improve over the next three to four months as the product wears off.

Thank you for your question.
In my opinion, the asymmetry you are having is from right lower chin injection. Based on your picture, you have weakness of the muscle of the right lower lip called depressor labii inferioris. Its function is to lower the lip. When inhibited by Botox, the lip on the affected side won't move down with smiling which results in asymmetric smile. It usually takes around 3 months for your symptoms to improve.
I hope this helps. Best wishes.

Injecting around the mouth is for advanced injectors because this is what can happen. I'm sorry this has happened. The chin injection hit the DLI on the right so you can't pull it down when smiling. The gummy smile injection prevents the upper lip from lifting. Some people like this injection, many don't. There's nothing to do at this point but wait it out. 

Dear mrc3121:Thanks for sharing your photos! You do have a gorgeous smile so I am sorry for your concern. The good thing is it will revert in 2 to 3 months. While injecting your chin, the Botox "spread" just enough on the right to weaken the depressor labii inferioris (DPI) muscle causing the round orbicularis muscle of the lips to lift that side. You may also regain symmetry with a couple of units of Botox in the DPI  on the other side. Discuss this with your injectors as an option. Don't frown! You have a beautiful smile! All the best!

If you were getting good results from your previous doctor why did you change. what you have now can be adjusted with Botox but I would go back to the original doctor you had to "fix" it as it sounds like he knows your face and needs better

It's unfortunate that this has happened to you. In general Botox use in the lower face is associated with a higher complication rate, hence the requirement of special expertise. There are many small muscles around the mouth which control your smile and by the looks of it the muscle which supplies the lower lip (depressor) muscle was injected or Botox has seeped from the neighbouring injection into the wrong muscle. Your lower lip should improve in time, less than 3 months. Much of it is also how the lip feels to you. Be patient and it should resolve. Hope this is helpful.

Botox in the lower face is an advanced technique. What appears to have happened is that not only was Mentalis (chin dimpling muscle) affected by the Botox, but also its neighbor muscle, Depressor Labii Inferioris. The DLI is a no fly zone-- Botox there causes an uneven smile. 

Unfortunately, the best option would be to wait it out. It wasn't the Botox that was injected for the gummy smile but rather the Botox that was injected near the chin which caused this problem, anatomically related to the depressor anguli oris ...BestDr Karamanoukian#RealSelf100 Member
