Foundation application can be tricky. Do you use a sponge? Do you use your fingers? Or is it that you are supposed to use a brush?

I'm sorry to say that I can't answer that question conclusively. But I can say that by and large, most makeup artists I know suggest using a brush. But sometimes figuring out exactly how to use the brush can be tricky. That's why Yves Saint Laurent Beaute developed the Perfect Touch Foundation. The first of its kind, the Perfect Touch is an all-in-one foundation bottle with a built in brush. Simply turn the brush to the 'on' position and the foundation flows out from the bottle. Turn it to the 'off' position and you can gently sweep your foundation on. It's practically fool proof! Of course picking out the right shade of foundation is a problem for another day.
