I've decided to get laser hair removal, and had a test done to three areas of my body today and they seem fine - i will wait a couple of days to ensure I have no complications. The machine used is a Gentlelase, and I have read that there is a higher risk of hyper pigmentation or burning for type 4 skin. My question is, what is a safe setting that will be effective and kill the hair, but not burn my skin? The tech that did my test said she will start with "7" and go up to "9" max.
