I can't make up my mind....?

I am wondering if i should see a doctor fot my acne. Sometimess my face appears fine and sometimes not. I went to facial, but i find that it didn't really helped me much. I think my acne is considered from mild to moderate(a bit worse, but not that worse). Do you know what i mean?? So, i'm thinking of asking my parents to bring me to a doctor. Should i do that?? Mine main problem is the blackhead, and it can't go alway.And my blackheads is really really a lot! If i were to ask my parents, what and how to say it to them???
