I'm 32 years old with nasolabial folds, I can't decide what to do. Should I go for fillers or PRP and maybe dermarollers? (Photo

I would suggest trying fillers. Restylane or Juvaderm might be good choices, for long term improvement you may want to do fillers with PRP. 

Dear Zeynep,
Thank you for your question. 
You have mild nasolabial folds which would respond significantly to fillers. Dermal fillers are FDA approved and have level 1 evidence for safety and efficacy. This has been repeatedly demonstrated in large randomised controlled trials for more than a decade. 
So my recommendation would be hyaluronic acid fillers.
I hope this helps.

You are a perfect candidate for a filler.   A syringe of Restylane or Juvederm will instantly lift the fold and should improve the crease for up to a year.  Nothing else will work as quickly.
