Normally I'm a bit wary of a powder because it isn't so good on the old crow's feet. Ok, so mine aren't really crow's, they're more like sparrow's feet...but yes, there's some lines coming in there under the eyes (all that time working outdoors on farms me thinks!)...but powder and lines don't mix so well. My solution is to simply avoid the eye area and work the powder into my cheeks and forehead with a kabuki brush. I have a lovely one from The Body Shop which hasn't had a workout for a while so it's good to give it some exercise.
So far I'm finding that this foundation is doing the trick in reducing the shine, and it will last me ages because I'm only using the tiniest bit. Dusty Girls is conscious of using natural ingredients and it also has an SPF15, which is really important in Australia. I got the 'Fair Minerals with Pink Sunrise Tones' and I highly recommend it.
