Review title is so it can get pretty hot down here [SEP] I live in the South, so it can get pretty hot down here. I also have some skin problems (mild to moderate acne, redness, dry flakes), so I like to wear base makeup whenever I go out. I bought this because I was hoping that combined with a primer and fixing spray, the skin prep pro would help my makeup stay put and not get swept away by the flood of sweat that comes crashing in every summer. The primer and fixing spray I use work well for me (or at least are the best I've tried so far) and sweat is still an issue for me. When this came in, I had high hopes, but unfortunately this is not a miracle product. It did make my face feel tight, so I applied a small amount of moisturizer over it after letting it set but before applying my makeup. I'm a college student, so I walk to class all the time, and after a few classes I could tell that my face was fading and melting as usual. It wasn't a pretty sight. So the next day, to see if it was due to the moisturizer, I just applied the skin prep pro before my makeup. Sadly, I got the same results. I break it out every now and again to see if it's a certain product that it won't work with, but after going through all of my routine taking one product out at a time, I've determined that this just doesn't work for me. I gave this two stars because while it didn't do what I wanted it to, it also didn't make any of my skin problems worse. I also want to give it the benefit of the doubt in case it is helping, just not significantly enough.
