How long after Sciton profractional laser procedure can I have the fraxel dual laser?

I just had Sciton profractional laser done 2 weeks ago and I realize I like the results from fraxel dual laser much better. Is it safe to get fraxel dual afterwards? And when is it safe to do so. I did Mlp 10 micron depth, followed by profractional 150 micron depth. My acne scars and hyper pigmentation is still there. And the Sciton laser added more rolling scars.
