At what laser depth do you expect significant results without having to go back for multiple treatments?

I recently underwent Profractional Laser treatment with a Sciton laser around 150 to no more then 200 µm (the nurse didn't specify, just said she "bumped it up" after seeing how well I tolerated the treatment) along with a microlaser peel that was preformed before the profactional treatment. My main concerns were (but not limited to) large pores, redness, and fine lines. I am wondering realistically what to expect from one treatment and if I should've opted for a more intense procedure.
