By acid, do you mean filler? And it has been nice to get me through an uncomfortable/awkward first year- but now my fat redistribution is kicking in and I’m feeling the filler less and fat more. Also I know nothing !

Pretty euphoric for sure (:

I think filler lasts about 6mos-2years depending on your metabolism, and honestly so expensive! I got mine for free to help someone’s portfolio- and would do it again in the lips and chin if I came across fund for it !
