Eon or Sculpsure for back and flanks?

Is it true the non-invasive, fat-reducing procedures for back and flanks can prove to be more difficult to see any noticeable results? I have a bmi of 25 and considering Eon or Sculpsure to treat my back/love handles. However, I also have tattoos covering some of my back/flank area and some practitioners said they cannot use Eon over tattoos. Any suggestions or providers who use both, and have experience with tattoos would be helpful. Seeking treatment.
