Were there no attempts to cover the moles with red ink prior to being lased? Did a physician evaluate the moles before treatment?
Sounds like they crusted over, but my understanding is, you don’t want to erase moles,with laser because there is no way you can then observe for funky changes in the future if they are not benign. I hope poster “sslhr” is still with us as he can give more detail about this. Or you can ask your doctor.
