Crepey inner thigh skin. Fraxel? Thermitight? Ultherapy? Microneedling?

There is not one answer as to which treatment is best for your crepey thighs. Everything depends on your skin quality and the degree of laxity you currently have. I'm assuming you noticed the crepeiness after you lost weight from your exercise routine. You would need to be evaluated in person to determine which therapy is best for you, or if a combination treatment is most appropriate. Be sure to consult a board-certified dermatologist who can offer you a choice between Fraxel, ThermiTight, Ultherapy, Microneedling or a combination of two or more of these to make the improvement you desire.

I recommend a combination approach for this area.  Sometimes a procedure like Thermi and VASER lipo can do give improvement to the thighs followed by RF tightening like exilis.  Sometimes a combination of in office procedures like profound, venus legacy, vanquish, coolsculpting and thermage can give improvement. I recommend getting a formal consultation with an expert.  Best, Dr. Emer.
