I'm surprised to see all these really negative reviews. I contacted JustAnswer after trying to make an appointment with a local dermatologist and not finding anyone to get in with for two weeks. My question was pretty simple, and a good photo showed most of what needed to be relayed. My question to the JustAnswer dermatologist was answered professionally and thoroughly, about 1 hour after I asked it. I had a continuing conversation with this dermatologist that lasted over the course of a week, with lots of great advice. I am a nurse practitioner and know that the advice given was sound. Admittedly, they do seem to charge you before your question is answered, so I am not sure about the claim that you only pay once you are satisfied. But I was satisfied, so I am happy to have paid what I did pay. I recommend the service with caution though, because clearly others didn't have the positive experience that I had!
