Will Fraxel Make Your Skin Thicker with Collagen Than the C02 Resurfacing Because the Pixels Go Deeper?

I know co2 gives the best erasing of age spots and fine wrinkles but if my skin is actually all over very thin I was wondering if the fraxel pixels actually go deeper than the co2 could do safely and thereby stimulating more collogen at a deeper level resulting in thicker more youthful skin (at least from the thickness aspect)
