Soap & Glory 'One Heck Of A Blot' Powder, £12.00 from Boots
I've had this blotting powder from Soap & Glory for quite a while now, and although at £12.00 its quite pricey for a high street brand it really is worth buying if you have oily skin (I'd just recommend buying it when Boots are doing their 3 for 2 offer so you get the most for your money).
The powder is a very pale white with a slightly yellow tint in the pan, but applies translucent, and most importantly, keeps skin oil free for a good few hours. I think darker skin tones might find this applies a little ashy, so it might be better to steer clear altogether. It's always in my handbag for reapplications and I take it with me everywhere I go for touch ups. The best thing about this is that it doesn't make my skin look cakey, like so many other powder products do.
There's not really much more I can say about this! It's well worth the money and much cheaper than high end blotting powders, I can definitely recommend it!
