Some people have these in their P0.
Personally, I would recommend somewhere with thinner skin where light will show up better, Like the back of the hand P1 - P4
Remember, once you install it, you’ll still need to wait 4-6 weeks (maybe a little longer) before you can see decent results, “everyone” is impatient and I think it should be working, they think they are all healed, and they, I can’t understand why they can’t see it, we see this time and time again!
It doesn’t help but generally after the initial install, it can be seen. But that’s before the body has started healing.
Just trust us…
