What IPL Settings Should Be Used for Light Freckles?

Here is the response to the reply to my original post. The Fitzpatrick 17 was a type-o. I have dark hair, white skin, brown freckles, and dark eyes. I tan well, but not easily. I'm not treating myself, but I wish I was. It's ridiculous to keep spending money on trial and error and treatments that don't work. Unfortunately, there are a lot of unskilled professionals and it's hard for me to find the medical books and technical specs of medical equipment as a patient to minimize risk.
