Hi I am 26, after losing a lot of weight due a disease my jawline and under neck are a bit flabby, I got 4 PDO barbed threads lift last month. They have not work at all in one side and only a tiny bit on the other side. I definitely don't want a necklift. My disease is cured now. I want to try Ultherapy.. how long should i wait untill to have it done, as i had the threads inserted last month? As well i want to know if i can have microneedling over the threads? Thanks and Best Regards
