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 have 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 am 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 was not 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 is a certain product that it will not work with but after going through all of my routine taking one product out at a time i have determined that this just does not work for me i gave this two stars because while it did not do what i wanted it to it also did not 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
