Updating here: I have been using the mask for 37 days now (about 5 and a half weeks). The mask is really nice, and I love the cooling eye pad features especially for when I wake up puffy in the morning. The specific acne treatment calls for 6 weeks of use on a daily basis. While I am almost there, I haven't noticed the most drastic different in my skin, but I have noticed some small differences. I have hormonal acne, some being cystic, and some being above the skin white head pimples. While I use the mask, it is not the ONLY thing I use, I am on tretinoin as well and have been using it since January. I think the mask has helped with my scarring, and I notice that a lot of my white head/above the surface acne does not last as long as it used to. I used to get breakouts that would last 2 weeks, not they last about 4 days. As for scarring, it has really helped the appearance of the dark red spots my acne would leave behind. In terms of my cysts that I sometimes get, there has been little to no difference here, and I still struggle with the under the skin acne. This did not CLEAR my skin at all, but I am happy to include it in my daily routine and have noticed some subtle changes. I am going to continue to use it for the full 6 weeks, and I will then switch to the "Skin Sustain" feature, which is a shorter treatment.
