How deep does the effect of RF microneedling penetrate to tighten skin on lower face?

Hi, there's a lot of talk about RF microneedling with all of them saying they're the best. From what I've read, seems Morpheus8's needles penetrate the deepest, but that may not necessarily mean the affect penetrates the deepest. I'm wondering if anyone can clarify if the depth of needle penetrate= depth of affect and what needle depth/RF device Tends to have the best outcome for lower face skin tightening. 50 yo male, 175#, non smoker, exercise 1hr 4x/wk.
