How long will it take for my lip flip to wear off

I've recently had a lip flip which I hate so much. My filthrum has lengthened and my bottom lip sucks up into the top lip...its a horrible look. I'm wondering does this treatment wear off sooner than other areas as its a smaller amount of botox used. Is there any truth to using your muscles in that area to try and wear the product off sooner...I just want my normal mouth back I feel like a Simpsons character. Thanks
