Potenza is a microneedling treatment that uses radiofrequency energy, and while it is generally safe for most people, there can be some individual variations in how the skin responds. It's possible that Potenza could lead to some degree of scar tissue formation, but this is relatively uncommon and usually occurs in cases of excessive healing or sensitivity. The treatment primarily works to stimulate collagen production, but in rare cases, if healing doesn't go as expected, there could be concerns about the formation of fibrous tissue. As for facial fat grafting, your surgeon's concern about potential complications due to scar tissue is understandable. If significant scar tissue or fibrosis develops in the treatment area, it could impact the grafting procedure, as the fat may not integrate properly into the treated areas. However, this doesn’t necessarily mean that Potenza treatments will always prevent successful fat grafting, as it depends on the extent of the scar tissue and the specific areas treated. If you are considering a fat graft in the future, it’s essential to have an open discussion with your surgeon about the effects of previous treatments, including Potenza. They can evaluate the condition of your skin and help determine if any healing adjustments are needed before proceeding with a graft. I hope this helps clarify things!
