That's why I said unless you are tan. I also noted it's ideally for people with light skin. We could draw from both of those statements that unwanted results could occur in people who are darker skinned.
It most certainly does not cause skin discoloration. Unless you are tan. And you are not supposed to be tan to have this done. This works on people with light skin and dark, coarse hair best.
I'm having it done. I had electrolysis done before... it hurt and I had very very very minimal...
