btw...not all of their products use s.a., and the reason they r giving u products with s.a. is because is FAR less harmful for dry skin than benzoyle peroxide. many products do use these because they work and are low cost on the consumer. you cant really complain much if you didnt even try the product in the first place. s.a. is considered the less damaging of these two products. also, due to the various different combinations there are, numerically, there is no way that you could have tried every one within a reasonable amount of time. using just stress and sweat, there are eighty different combinations. there are far more portions to the test, as well. as for the sales rep...it was a sales rep...they will do anything to ensure that you keep the product...thats what they are paid to do. also, that particular rep was obviously not very knowledgeable on the product and really should be fired for that fact alone, because most of my products do not contain s.a. at all.
