How long after a mid and lower face PDO thread lift can you resume sexual intercourse? Also, after I had my first PDO thread lift, the results were gone within 2 weeks so I had to have more put in. Is it likely that these new ones will not work too? How easily do these things unhook from the skin because I was extremly careful. How long until they're secure enough that I don't have to worry? Thank you for your time.
