Could use of a medical tens unit forehead device migrate Botox or break down Juvederm in the frown lines or forehead? (Photo)

I am a migraine sufferer who uses a medical tens unit for head device to control my migraines. The device is called Cefaly and targets the trigeminal nerves. I recently got cosmetic Botox + Juvederm fillers in my frown lines. My device is worn over the exact area I got cosmetic treatments. I'm worried about Botox migration or breaking down the fillers from the Cefaly's nerve stimulation. I contacted Cefaly and got no answers. How long should I wait to use the device after cosmetic? Thank you!
