Worried after first SMP session

[Rg1911]

I had my first session a couple of weeks ago and go back in a few days. I have followed all of the aftercare instruction but about 7 days after I noticed a good amount of fading, and it got worse. I contacted my technician and she told me it wasn’t normal to have that much fading but would address it in the second session. However she also said that if my body rejects the process she will refund me. Is it possible that SMP can not work for some people ??
