Is Alpha less painful or hot than the existing Density?

I saw reviews saying that the procedure for Density Alpha is a bit easier than the original Density, so I was curious to see what it was actually like. .

For those who have received both the original Dencerty and Alpha, did you definitely experience less pain or a burning sensation during the procedure? ?

Did the sensation vary greatly depending on the treatment area or the number of shots? , I am also curious how you determine the maintenance interval. .
