Cetaphil is known to be a good cleanser, but I think it can be a little mild for that age group -- youngsters with lots of oil. Cetaphil is better for older skin.
There are many good face cleansers -- try Almay or Neutrogena. But I wouldn't get the kind with the acne medication at this point -- that can be a little harsh and actually activate the oil glands to produce more.
