Dermapen or Picosure for mild acne scarring? (photos)

I am a 30 year old male with mild acne scarring and enlarged pores on my cheeks, plus one small dent from a mole removed by radiolaise that was a mistake by the dr... I have had dermapen twice and tca applied to the small dent twice. I haven't seen great results so far and am thinking of trying picosure now however it's hard to find strong cases studies. Which treatment would give the best results or another treatment all together? I am unable to do a treatment with a long down time..
