i just seen this commercial on tv. it looks amazing i always wanted an airbrush set. but i am a little nervous on purchasing this product. my skin is pretty fair i do not really have many blemishes but what i do have is very light sun damage. i just have some questions if someone can please help me out!

when you apply the make up does it look cakey?
how long does the make up last you before you have to buy more?
is the machine easy to clean?
can i use a powder blush of my own?

please help me thanks girls!
