"Failing to prepare is preparing to fail"
My biggest skin worry was, admittedly, quite shallow - I worries as to how it looked to other people. As much as I loved make-up and spent all that time working on it, my skin would let me down. I was afraid people would think - Who is she to talk about make-up when she can't get her skin sorted out.
The most important steps in make-up application are the steps before you even open your make-up bag. You need to prepare your skin. Prep - to many people this may mean putting on a primer before your foundation, but I'm talking even before that.
