The Benefit Primer That Outlasts Birchbox Co-Founder Katia’s 15-Hour Day

I have always been a bit skeptical of primers—they tend to have zero effect on my oily skin and my foundation never seems to last through lunch even when I use them. That said, I am really excited about Benefit’s new primer that promises 15 hours of flawless makeup. The stay flawless 15-hour primer is super easy to apply for lazy girls like me and the packaging is simply adorable!

After testing out the product myself, I’ve become a primer convert. The strong-hold formula, which you apply straight from the chubby stick, truly makes my makeup last, even in the humid city weather. I’m now less of an oil slick by the end of the day! Check out the video below to see how it holds up with Birchbox co-founder Katia’s busy 15-hour schedule. (Spoiler alert: it does).

Benefit Stay Flawless 15 Hour Primer

This is a glue stick like primer that has been getting a lot of hype since before it came out. Most reviews rave about how amazing this primer is and that it works wonders, but I have to disagree.

When using this primer, you have to apply it on by sections on your face. So first you apply it to your cheek, rub it in, and immediately apply your foundation to that section. This is how you’re supposed to use it. That itself is more time consuming then rubbing it all over your face and applying all your foundation at once.

Another thing I did not like about this primer is how sticky it is. It literally feels like I’m putting glue on my face. Maybe that’s what helps with the 15 hour staying power but I do not like that sticky feeling it gives to my skin at all.

Although the primer did a good job of keeping me from getting oily in my t-zone, it is not something that I will be purchasing. It’s just too sticky and uncomfortable on my skin.

I’d rather stick to using my Porefessional primer.
