Following a PDO thread procedure (3+ wks ago) one thread (temple area) is slightly protruding. It appears to be moving anteriorly, as though being pushed out by the skin. RF treatment to accelerate dissolving the thread has been proposed, however I read a paper by Li, Xang, et al (2022) which found that PDO+RF actually amplifies inflammatory response, fat necrosis and nodules (granulomas?). How much of a risk is this? Can a thread keep moving outward? Is RF really recommended? Thanks
