How about using semi-permanent thread lifts that provide long-lasting effects?

I'm interested because I've heard that thread lifting is effective for sagging facial flesh.
PDO thread lifting, which many people use, usually requires a touch-up about once a year to maintain the effect.

I found out that there are also semi-permanent, long-lasting thread lifts.
Are there any side effects from using semi-permanent ink that does not dissolve well in the skin?

I'm curious if there are any people who have experienced semi-permanent thread lifting procedures.
