If you haven't heard of the real techniques brushes, where have you been? These are huge in the beauty world at the moment.
I was bought the expert face brush for my birthday and have literally forgotten my previous foundation brush. I absolutely love the way it glides my make up onto my face. They are a reasonable price, particularly if you pick up a pack. Keep an eye out for an offer in boots or superdrug!
I'm on the look out to buy some more, I've heard so many good things about these, it's worth the investment.
