This powder is such an essential in my beauty bag. I often get oily around my eyelids and forehead and Rimmel Stay Matte Pressed Powder in Transparent works well to mattify my oily areas without added colour - which is exactly what I want to achieve. I'm not one on spending tonnes of money on transparent powders and Stay Matte does the job and does it well (and is super cheap - I get mine from ASOS!). The pricing in New Zealand, though a bit steep, is still better than other powders which are overly priced yet achieves the same thing. Again, I suggest getting yours from ASOS.com who hold a variety of the shades and sell if for around $8 (plus is always on sale). The powder is very effective and doesn't look like powder when applied on the skin. In fact, it blends effortlessly and disappears completely - only leaving a matte effect on the required parts of my face.
I find that my makeup also stays put (and matte!) throughout the day with very little required touch ups (if ever!). This will depend on how oily your face gets as this will vary among different people.
Overall: love LOVE this powder! I use it every day and endlessly hit pan!
Absolutely love this powder! You will ALWAYS be able to find it in my makeup bag or out on my vanity. It sets my makeup perfectly without making me look caked, covered in powder, it doesn't make my skin appear dry just a nice matte, and since it is transparent it doesn't cause my skin to look overly orange which is great! If you haven't tried this before the next time you see it grab it and give it a shot! I'm sure you won't regret it.
