Can Microneedling RF cause loss of facial fat and/or scar tissue?

Thank you for this great question. The point of RF microneedling is to cause a thermal injury to the skin that causes not only collagen buildup from repair but also causes some constriction of the skin for tightening. But you are wise to bring up the question of fat loss as fat tissue is prone to thermal injury as well. There are devices on the market that are specifically used to dissolve fat with thermal injury. The answer is in the depth of the treatment needle. If the depth of the needle and the thermal spread of the needle passes out of the skin and into the fat tissue underneath, then there is a possibility of damaging fat cells. Same goes for the facelift question, although I would be less worried about this with facelift surgery as the amount of scar tissue created and the depth of the treatment is likely more superficial than the level of surgical dissection.All this being said, if you are concerned about aging changes and considering at some point in the future you might need a facelift, my question to you is: Why not now? Why spend time and money on minimal procedures that are not going to create the outcome you really want? Save your money and save up for a surgical procedure that will deliver the results you really want and that will last you 10-15 years!Hope this helps!Dallas R. Buchanan, MD, FACS

With the proper use of appropriate energy and depth microneedling with RF is a safe and effective treatment which provides excellent results for skin tightening and remodeling with minimal risk of scar/unplanned volume loss.  Which is why is so important to have your treatment performed by a board certified plastic surgeon with appropriate understanding and experience of this device. kh

In the context fo RF, namely Lutronic Genius the depth of needles can be up to 3.5 mm deep. In theory with long long PD and high energy settings with repeated pulses, fat loss can occur. This applies to many other devices if use inappropriately. In the context of your second question, RF is unlikely to cause idiosyncratic scars. Dr Davin S. Lim. Brisbane. AU
