Benefit Stay Flawless 15 hours primer* is one of the newest additions to the Benefit make up family. The design of the packaging shows that it is a younger sibling of the Hello flawless oxygen wow! foundation and I think that it is great that the Benefit team decided to match-up these products into a one theme.
I love using the primer before I put my foundation. I tried and tested some really good ones and those which came mediocre. But this is now one of my firm favourites! When you open cute polka-dotted cover, you twist a stick and voilá - here's your primer. Then simply glide it onto the skin and immediately apply foundation - blending two together on your face. You need to remember to apply the foundation quickly - it settles really fast - but that's one of the reasons I like it so much. With some primers you need to wait for product to sink in, otherwise you'll be left with patchy skin.
What is really special about it is that it acts like a magnet to lock on your foundation for a whole night (or 15 promised hours). I was lucky to come to the launch in London and as a souvenir in our goody bags we've found two metallic cards - one representing the face and the other the foundation. Alone, they didn't stick together, but when we'll put a magnet-primer in between, everything falls into place.
I tested the primer under a various circumstances - from a clubbing night to a whole day outings and I can honestly say that it is fantastic. It really does keep your make up fresh and delightful all day. Easy to use and with super cute packaging it simply works and gives me perfect smooth and matte finish I always want.
