Being a fan of maybelline products - I decided to try this product out of curiosity. Usually with primers I look for ones that make my make up last longer, apply better and make my face base flawless and unfortunately this did not meet my criteria.
Upon application of this primer, I found that it didn't fill in my pores (it just awkwardly sat on top) and did not make application easier, my skin was not smoother after application at all.
In terms of longevity - this product doesn't claim to prolong make up - but managed to do the opposite for me. Halfway through the morning I found that my make up was slipping and sliding off my face - my T-zone was oily and the makeup looked like it separated on my face (note that I use powder foundation so it shouldn't matter whether my primer is silicone or water based). Overall, I wouldn't recommend this to oily faced people.
I love this primer! For a drugstore primer it works amazing on the skin. It is a siliconey type consistency but apply's really easily to the skin. It is soft and makes your skin feel velvety. I don't have any major issues with pores on my face but I did find it was the perfect base for foundation as it smoothed out my skin and made it a lot easier to buff in my foundation. This product is quite pricey in NZ supermarkets so I definitely recommend ordering it online.
