Benefit Stay Flawless 15 Hour Primer Review

Hello Beauties!

Today’s post is about a makeup primer that I had been looking forward to trying for weeks before its release. This is Benefit’s Stay Flawless 15-Hour Primer – a long-wear primer that keeps makeup on all day while controlling shine and enhancing the look of foundation and your complexion.

Benefit Stay Flawless 15 Hour Primer Review

Claims: Benefit promises that this twist-up stick primer will lock on to your foundation like a magnet and keep it fresh for up to 15 hours with a natural finish. Pretty ambitious, I know.

Speaking of pretty, let me just get this out of the way. Look at this packaging!! One thing I must credit Benefit with is that they always come up with possibly the cutest packaging possible for their products. Who can really resist Polka Dots? This Stay Flawless primer is unique because it comes in a solid tube form that is applied directly on the skin (like deodorant…hehe).

The color of the stick is a soft peachy color but it is transparent on the skin. See the ‘swatch’ below. The primer was applied between the two black lines. To use on the face, the instructions state to apply in small areas and immediately brush or rub on the foundation so that the two can blend together before the primer dries.

Now lets get down to business. First, there are some things to consider about this review.

What You Need to Know About Me:

  • I have oily skin (especially in the T-Zone)
  • I live in pretty hot and sometimes humid climate right now (75-100 degrees Fahrenheit)
  • I apply my foundation with a dense synthetic brush
  • I have used this primer with the following foundations:
    • Clinique Stay Matte
    • Lancome Teint Idole Ultra 24H 
    • MAC Pro Longwear
    • Revlon Colorstay
    • Revlon Colorstay Whipped
    • Revlon Nearly Naked  

 Review Time:

I have heard so many good things about this primer, but to be honest, I am pretty disappointed. Overall, I really did not notice thaaaaat much of a difference between using this as a primer and not wearing one at all. After about 2 or 3 hours my nose was as its usual grease-ball self and after about 4 hours, my entire T-Zone was ablaze with shine. Bear in mind, when I say my face can naturally get oily, I’m not joking! I can get OILY! So, maybe this particular primer just doesn’t have the muscle to deal with that.

I honestly never expected my “Flawless” to last for a whole 15 hours like it claimed, but I didn’t think 4 or 5 was unreasonable.

Another issue I had with this product, despite the lasting power, was the potential it had to make my foundation a bit cakey. Of course, I was careful with this during application but the problem arose when blotting my face throughout the day. After a gentle blot to get rid of the shine, I noticed blotchy patches between the primer and foundation that looked a bit sticky and required rubbing in to look ‘normal’.

To make sure the problem wasn’t with the foundation I used, I tried a variety of formulations and the results were basically the same.

The best lasting power I had was with MAC Pro Longwear and the worst was surprisingly with Clinique Stay Matte.Go Figure. I didn’t have as much of a blotch problem with the Revlon Nearly Naked.

Although I really like the outside of the container, my inner germa-phobe is just a wee bit concerned about rubbing the same stick on my face every time. Granted, I always use it on a clean face, there’s still a little irking I get when I think about the potential for reapplying bacteria. Is that just me? I guess it goes without saying (sort of) that sharing is pretty much out of the question. Ha!

So now you’re whining saying “But Christaaaaaaaal, isn’t there anything good about this primer?”. Don’t worry, I hear you.

The Benefit Stay Flawless Primer does have some good traits.

  • The packaging is obviously so adorable that you could probably eat it! (please don’t)
  • Its really travel-friendly
  • It applies easily to the skin and blends with foundation as long as its done before the primer starts drying
  • The packaging is cute! (Oh wait….did I say that already?)

So, there.

Please note that this was just my experience. Based on all the reviews out there, this product must work well for SOMEONE!! That someone just wasn’t really me. Perhaps if you’re not as big of a grease-monster like me, you’d have better luck.

The Benefit Stay Flawless Primer is sold at Sephora and Ulta for $32.

Overall, I would rate this Primer on the L&P Scale at 2.5 out of 5. The packaging saved it from 2 🙂

So tell me (because clearly I need help), did you try this Primer and have a good experience?
