Very mild Fraxel Dual - did I waste my time and money?

I had a Fraxel Dual treatment & have almost no side effects. I contacted the derm & requested the protocol used: Fraxel restore 1550nm only, energy: 65mj x4passes, depth: 1332u, treatment level: 11, total coverage: 32%, coverage/pass: 52mtz/cm2. From the literature I've read, both modalities are used, 6 - 8 passes standard. My concerns are fine lines,wrinkles, sun damage, collagen loss. I would appreciate a professional view as it was expensive & I worry I wasted my $. TIA :)
