I've been using this product for about a month or so to help deal with my giant, constantly sebum-filled pores.  I use it after my cleanser, toner, and a hyaluronic acid serum, then some additional products afterwards.  It definitely helped moisturize to help with minimizing pore size, and since I worked it into my routine, I have noticed my skin getting significantly less oily as the day goes on, with or without makeup on.

I feel like I've used products that are better, but I'm definitely not disappointed with it either.  Unless I find an alternative with a similar price point, I will probably stick with this product for the foreseeable future.
