Dear Terry, Thank you for your question. Threads can be divided into absorbable and non absorbable sutures. The trend now is for absorbable sutures, of which we have PDO and PLLA. Threadlift is a minimally invasive treatment, and it appeals to people because of this fact. Removal of a thread is not so straightforward. The tissue trauma, swelling, bruising and pain makes it a rather invasive process so many doctors feel it is much better to give time to allow for the threads to dissolve. After a threadlift procedure, it is best to wait for swelling to settle, which takes up to a month, before doing any further work. After 3 months, neocollagenesis occurs. PDO sutures would have dissolved to a good extent, while for PLLA sutures, there is a core of collagen around the suture, making it extremely traumatic to remove. In general, it is best to not remove absorbable threads unless there is a strong medical reason, for example infection. Skin irregularities will resolve with time so there is no need for thread removal.
