Not really sure what I would recommend to you. Its difficult to pick so what I end up doing is starting cheap and trying out a few different ones.This is a good review website at http://www.brandsmakeup.com visit and see what everyone recommends.
Use a primer and lightly dust with a good loose powder.





PRIMERS





Rimmel Makeup Primer


Sephora Skin Smoothing Makeup Base (said to really make a difference)


Smashbox Photofinish Foundation Primer
try to dab it gently but make sure you put enough on the brush , don't overcoat put an even amount this way you won't use a lot!!
use a primer or moisturiser first :)
