This product is quite pricey but a little goes a long way and the tube lasts for ages. It made my skin glow beautifully under my makeup and definitely smooths out my skin and makes my makeup last for ages. You have to make sure not to rub it in but pat it on, and then apply your foundation over it as quickly as possible. I usually wait for a couple of minutes after that to apply powder and blush.

I've also tried mixing a tiny bit of foundation with a small blob of it and making a sort of tinted moisturiser with it. Works beautifully.
