You should consider reaching out to Dermatologists in your area. Ask your parents for your insurance information/provider, use their website's Service Provider Search feature/thing to look up Dermatologists in your area, and make some calls to ask - respectfully - if they would be interested in answering some questions. You'll probably find someone eventually with 10-30 minutes free sometime to talk and answer your questions about their industry.
Truly, the more I put myself out there and make an effort to meet people, the more that I realize how much people enjoy talking about themselves and their work and their education. Just be honest and polite and eager and respectful of their time.
