Hello. I’ve been doing under eye fillers and temple fillers all winter until my doctor around end of March suggested to use threads to “fill” the areas (not to lift) as they were going to be more permanent. I’ve been struggling the last 3 months with threads puckering as they’re are clearly visibile unless I fill the gaps with fillers. They look like little snakes under my skin and unless the gaps between them are filled I feel very insecure. What type of filler do you suggest here?
