I was in love with this product, then after a few months it wasn't helping anymore. I bought the zap kit a few months ago, and I instantly fell in love. My acne started clearing up right away. I didn't use it everyday as I found it really dried out my face. But with using it about 3 times a week before bed, I was really happy with the results. I have hormonal acne, especially around my chin ad jaw line (to give context). While using this product I still had a few bumps around my time of the moth, but other then that my skin was pretty clear. After a few months went by, I found that my acne started coming back. I think my skin just got used to the product, so it wasn't having the same interactions it did when I first started using it. So now I'm disappointed with the zap kit, as it is not a long term solution for me. I use the zap roller pretty consistently to help dry out acne. But it isn't a preventative measure. I the rest of the kit once in a while now, mostly because I have it.
