Query: Didn't work for my teenage son, and he gave it awhile before giving up

My son doesn't have terrible acne, he just has a lot of smaller breakouts on his forehead. I thought for sure this would work since the reviews are so great and his acne is pretty mild. Well, he used it for months and nothing's really changed. We're moving on to something else now. Maybe this isn't great for oily, hormonal, teenage skin
