One session lasts twelve to eighteen months. It fills and lifts the moment it goes in, and the final shape settles over four to six weeks, because the supporting and lifting threads each bed in and the surroundings take time to adapt. Collagen remains after the threads dissolve.

It is done under local anaesthetic. Downtime of five to ten days is needed, and because two thread types go in together there is somewhat more swelling than with one alone. Since the irritation stacks, allow extra recovery time, and skip saunas and hard exercise for two weeks.

The volume thread supports from beneath while the lifting thread pulls, so at first you feel both a lift from below and a pull. It becomes natural once the two bed in. The combination and number of threads differ by clinic, so it is worth confirming in advance how they are combined.
