Are any of these products good for acne and why?

All the St. Ives, Clinique, Neutrogena, Body Shop, Aveeno, and Olay products are excellent, believe me. I happen to know because I have all the products you mentioned from these product lines. Neutrogena and St. Ives are really good for gradually clearing your skin and making it feel really fresh and clean. The Body Shop products are good sometimes, but sometimes they irritate my skin. The others I haven't used enough to recall. Hope this helps :)
