Unfortunately, on the ingredients list of the Acne Starter Kit for Sensitive Skin product page, Benzoyl Peroxide was not listed under the Acne Gel which is one of the reasons I got it because I am allergic. When the product arrived, i had an allergic reaction and my eyes got extremely puffy and red (I did not place directly near my eyes) and then I went to the Acne Gel product page and saw that Benzoyl Peroxide was listed there as the main ingredient. Had I seen this on the product page of the item I was purchasing, I would not have ordered it. As for the other products, they are nice but I have not seen an improvement in my skin yet.
