Be patient.

It takes time to slowly accumulate enough throughout your body to start to show up at all. If you try to rush things you may make yourself sick with side effects and get discouraged.
I have Type 1-Type2 skin and I didn't see anything worth mentioning until I'd had at least 50-60mg done. I did 10mg once a day [using 30mg insulin needles to squirt bac water into vial X 7 squirts = 30X7 = 210mg].
My second time around is taking less time to see a change but it still takes time.
Here (I think, if I post the link correctly) is my log if you're curious what I did:
