Best Infini RF settings for neck laxity/crepey neck skin? (Photo)

I would like to have RF microneedling done but I understand that there are a lot of things to consider when it comes to the operator and them having full knowledge about what settings to use on my neck. If I have this done, what settings would be the most appropriate for Infini RF microneedling on the neck skin if it has lost laxity and has some crepeypness on the front? I would like to know the best settings for the depth, the energy, and the duration?
