I am not someone who can be bothered with primers on most days. Part of it is laziness, but mainly it's because I feel like so many primers are gimmicky and ineffective. For my combination/oily skin, I tried many products out there before concluding that there's not a miracle product out there that would make a big difference to the longevity of my makeup.
Then I received a sample size of Hourglass Veil Mineral Primer with a Sephora purchase and used it without really thinking anything of it. My first impression was wow, that IS really smoothing. Applying makeup was a dream, my brush just glided along effortlessly. The real test came around midday at work. While I wasn't completely matte, the shine showing through was minimal but I was really impressed at how fresh my foundation looked! Since using that small sample size, I purchased the smallest bottle of the primer available.
This is some serious heavy duty stuff--I've not found a primer that comes close to keeping my makeup on for so long or making a noticeable difference to where I would go out and buy the full size. Again, I don't use this everyday because I don't feel like I need my makeup to be picture perfect all the time. But for special occasions or photo shoots, I know I can trust this product to keep me looking my best.
This has that silicone feel that a lot of primers tend to have--it feels slippery when applied. It does leave a white cast if you apply too much but it does disappear in a few mins. Just a thin layer is all you need, though. I like how it hides my pores and fills in lines so that my foundation has a nice smooth surface to adhere to. I thought maybe it would clog my pores but I've had no skin issues with it so far. It also has the added benefit of sunscreen. It could be a negative--sunscreen sometimes caused flashback in photos but I haven't had a problem with this one--so definitely check before using this on a big day with flash photography.
