Review title is Adult acne sufferer is super pleased!!! [SEP] The active ingredient in this set is the Benzoyl Peroxide at 4.25%. Which, if I am not mistaken is a pretty good amount. The packaging on this product says &quot;Step 2&quot; treatment. I am not entirely sure what that means unless it means there is a clearer to use first? I have also used the the cleanser made by this company and it really helps get rid of oiliness. I was super happy with that product so it seemed logic for me to jump all over this spot treatment product when I was provided the opportunity to purchase it at a discount in exchange for my honest review. So, I use the cleanser morning and night, pat dry and then apply this spot treatment to the breakout areas (usually my chin) and the fast acting treatment dries out the acne. I was able to tell a marked difference in how the acne dried out after the very first night. Also, it did not appear to dry out the skin around the breakout like some other harsher products have. As a longtime sufferer of adult acne, I think I have finally found a one, two punch to help knock out my acne problems once and for all!
