I would like to start laser for a Brazilian preferably on the gentlelase. Can anyone give me advice on spot tests? How long do you wait after a spot test to begin treatment. The place I called said you can do spot test and then the whole treatment on the same day. I was assuming a spot test is to see how your skin reacts later on, no? I appreciate all advice. This is the same place a cousin has traeted her entire body, including Brazilian.
