Fractional Laser + PRP Results?

What kind of results can I expect if I do one session of Fractional Laser Treatment (the one where the skin peels and becomes red and all), followed by three-four sessions of PRP (Platelet Rich Plasma)? Info on me: Age: 30 Skin condition: No acne, there are dark circles and some shallow smile lines. Also I feel that my skin is not as tight as it used to be. What can I expect from these sessions and how fast will the results be visible?
