Pimple Facts

Cause I heard that certain places where acne develops could be other causes. Like when acne is on the nose it could be hormonal imbalance. So I was wonder what does it mean when you develop acne like at the corner of the nose but its in the mouthstache area.

I have a minor acne problem on my chin and the corner of mouth. I recently went to the dermatologist to find out how to get rid of it. She prescribed oral medication that treats acne. My question is how does the oral medicine know where the acne is and how does it clear it up? I guess I’m just really skeptical about this whole thing. Thanks!
