acne treatment

I have real smooth face.I am just one of those few people that do not have problems with acne.So lucky I was born to have healthy skin aside from having scars of course. I never had a single big pimple,if there was any,it was just so small that was not obvious.Thanks goodness. My classmate in highschool was the exact opposite of me.She just had acne all over her face including her neck and back,I do not know why that was. I told her to buy acne treatment so it will get atleast a little better.She did not listen.
