What is the longest expected time for the Silhouette Instalift thread to last before it dissolves? I have very evident lines.

It’s been just one month since I had Silhouette Instalift threads placed on each side of my face .I have bumps and raising of skin along the sutures that look like lines . I am being told that it is the skin creating those irregularities as opposed to the threads. They are treating the skin with ultrasound but I think they are going after the wrong issue . How long until the threads dissolve ? Will any of the possible collagen reaction form in the same lumpiness as I’m experiencing now ? Thanks
