This is a NY Times "Skin Deep" article about (b)acne in young women, for the most part. It's kind of "fluffy" but there is some useful information. For instance: "Clearasil Ultra On-the-Go Rapid Action wipes ($4.49) with 2 percent salicylic acid" are inexpensive and probably as good a products that cost many times more.
