Microneedling with RF, is it different?

Yes, in one stated way. With radiofrequency microneedling, the needles also deliver heat, so ask which version you are being offered.

Research papers abbreviate radiofrequency microneedling as RFMN.

What each source says

Cleveland Clinic says microneedling stimulates the growth of collagen and elastin in your skin. NCBI PMC adds a detail for the radiofrequency version: in RFMN treatment, microneedles deliver thermal energy into the dermis.

Plain microneedling is described by what it prompts in the skin. The radiofrequency version is described by the energy the needles carry. Neither sentence ranks one version above the other, so do not treat "different" as "better".

Other non-surgical options in the literature

Other non-surgical options appear in the literature too. See an NCBI PMC paper on micro-focused ultrasound for skin tightening of the mid and lower face and UCLA Health's page on non-invasive facial rejuvenation. Microneedling is also studied outside skin care, as in a PMC comparison of PRP with PRP microneedling in androgenetic alopecia.

Confirming which device is planned

Ask your provider whether the device they plan to use is plain microneedling or radiofrequency microneedling. Write the answer down so you can compare quotes on the same footing.
