51 y/o concerned about sagging lower jaw - would Microneedling RF deliver results and what are the risks of hyperpigmentation?

The issue described here is one that any active cosmetic dermatology practice encounters practically every day. The use of a robust HA filler appropriately injected along the jawline and in front of the ear offers a simple, quick and easy approach to defining and straightening the jawline and diminishing the sagging and jowl formation there. Clearly, you have already been disappointed with one of the "bells and whistles" devices out there whose hard science to support their use unfortunately lags well behind the heavy marketing to promote them. So, instead of wasting more money on some faddish, supposedly "next big thing" device, it would be wise to consult with an experienced, board certified cosmetic dermatology injector. Hope this helps. Best of luck.

The sagging of the lower jaw can be dramatically improved with microneedling RF. One of the strongest device for the lower half of the face/neck is the Profound RF. It is the deepest microneedling RF on the market and can only be used on the lower half of the face and not on the upper half. It will tighten the jowls and my clients have seen great results from it.
