I'm not sure but if it helps, I used to use this as well as my mom and several of our friends. She has aging skin, I have acne prone skin that tends to be too oily or too dry (no in between), and our friends had normal skin, oily skin or dry skin. It helped us all. It did make my skin a little red immediately after using it but I have sensitive skin also. We used the entire line including the warming scrub/mask which I loved and miss since we've stopped using this.
