NuFace after Masseter Botox - will it ruin my result?

I had my first time masseter botox for teeth grinding and trying to narrow the square face I got from my masseter. I have the Nuface but I am not sure if I should still use it on my jawline or it would work my muscles for the square face. Should I avoid the jawline now? I aim for a more narrow, V face. I had botox 2 weeks ago. Thank you!
