Can ultherapy done only on undereye melt the fat of the cheeks and sag it?

I have five years of experience with Ultherapy and I have never seen fat loss as a result of treatment. It sounds like you have been treated not with MFUS but a HIFU or RF device that heats a wide area under the skin and depending on the device can cause fat loss. Certain devices advertise that they break down fat.
I hope this helps.

Hello and thank you for the inquiry. Correction application of Ultherapy technology should not cause fat loss or further exacerbate the quality of the skin. I recommend an in-person evaluation with your performing practitioner to asses your treatment results. When you are exploring the options of facial procedures, make sure that you also explore the right type of cosmetic doctor to perform your procedure. Clear communication with your practitioner is your best tool in getting the appropriate procedure that's suited to the goals you're looking to achieve.
