Two weeks ago tomorrow I had subdermal renuvion in my throat/neck. I developed these deep ridges/bands immediately after the surgery. My doctor is not concerned and says it's just post-surgical lumps and they will go but they're so deep and rigid and don't seem to be fading very much. PS he used vasolipo to go in but did not remove any fat at all. I can't find any other references to this result anywhere online.
