Is microneedling treatment safe 3.5 months after revision Rhinoplasty???

Hello. I'm considering a microneedling pen treatment to my face. I had my revision rhinoplasty on February 23, 2016. I'm now 3.5 months Post Op. Is it safe to have the microneedling pen treatment to my entire face, including the top and sides of my nose? Is it safe to microneedle the alar scars under my nostrils at this point? I've read microneedling does wonders for scars. Or is it too soon? Again, I'm 3.5 months post op revision rhinoplasty. Thank you!
