How effective is Pico Toning?

Is Pico Toning effective? I'm looking into it because I'm really bothered by the blemishes and dullness on my face. I've heard that it definitely lightens melasma and freckles, so I'm wondering if my skin tone actually brightens after just one session. I've also heard that Pico Toning improves pores and fine lines; does it only target pigmentation, or does it also have the effect of smoothing out the overall skin texture? I'm curious if the pain is just a stinging sensation, if anesthesia is required, and if I can apply makeup immediately after the procedure since I work. Do the results usually last after about 3 to 5 sessions, or do I need to get them consistently? Please share your honest experiences regarding before and after changes and the duration of the results.
