Claiming to 'act like a magnet' and keep foundation in place for up to 15 hours, it provides a super light finish which is easily absorbed into the skin. It leaves a slightly clammy feeling on the surface, aiding the 'magnetic' action and allowing foundation to really stick in place - I felt the foundation I've been using for many months applied more flawlessly and provided an even finish with little blending. If primers are a new area to you, or you don't want anything too heavy, then Stay Flawless is a great introduction to the concept from Benefit; it's easy to use, is invisible on the skin and is pretty much impossible to apply too much. Although this did aid application and act as a 'magnet' to my base, it didn't prevent the shiny look from creeping up on me throughout the day: in the afternoons I'm still needing to touch up my makeup and apply a dusting of powder to remove the excess oil.
In my opinion, this isn't a primer in the traditional sense. It doesn't create a barrier between makeup and skin, but just aids application and enables your base to sit in the way intended. Although it's a great introduction to those not so familiar with how to use primers (and a great accompanying product to one of my favourite foundations ever,) for me it's not quite strong enough. I like to be able to leave the house confident that 12 hours later my makeup will still be looking great - with this, I know I'm going to need to touch up before hitting the cocktail bar. Although that's not a huge issue, it would stop me using this on days when compromise just isn't enough. What do you think of Benefit's latest launch?
Stay Flawless is available from Benefit counters nationwide, as well as online, for £24.50
