Fractional CO2 Ablative Laser or SMARTSKIN CO2 Front of legs from the knees to the top of thighs?

I had my procedure on 9/14/16. I still have the discoloration from the procedure and also my skin is like sandpaper and I have more wrinkles especially around my knees, actually creases now! How long before they go back to normal, even if this procedure does not work, will the skin on my legs at least go back to the way they were: no discoloration and way less dryness and wrinkled skin??? That's all I'm hoping for at this point. (I am a caucasion female 56 years old.) Thank you
