I am curious about the side effects after the procedure.

I am wondering if there are cases where the face looks unnatural after a lifting procedure. In particular, I have heard that thread lifting can cause a feeling of excessive pulling, and I would like to know if this is actually the case.
I am wondering if there are cases where Ulthera or Thermage can also make the cheeks look sunken.
I would also like to know what criteria I should use to choose a hospital to minimize side effects.

I am curious if facial expressions often become awkward after getting Botox.
I would also like to know if it is possible to get a natural-looking result by adjusting the Botox dosage.
