I have acne scarring, which it seemed was the reason that he was so helpful. But even if this is not true of you, you should still press your doctor to give you something for your skin, as the prevention of it getting to a stage of scarring, or just spreading, will no doubt benefit you immensely. Basically, as I'm sure you well know, stopping it early is by far the best thing to do.
As you can probably tell from this, I regret not going to my doctor earlier, and I feel that had I have done, I could be sitting here with clear/er skin.
One of my friends, whose skin isn't as bad as mine, went to the doctors, and he was given an antibacterial wash, which has made vast improvements to his acne. I don't know, but this may be the case for you.
