Is the pain from the ball nucleus very severe?

How severe is the pain?

Since it is a procedure on the face, this is what I am most concerned about... whether it will be too hot, or if it is bearable.

I am also curious if there are many reviews saying that the procedure is painful.

And how long do the effects last? Since it is not a cheap procedure, I am also curious about how long the results last after just one session.!!

How many months,

I wonder if maintaining it about once a year is sufficient.

I would also like to know if there is a big difference from person to person.
