If you are looking for a grown-up, brightening powder that gives a dewy glow to the face then By Terry's Brightening CC Serum Powder may be the one for you. It's a high end product costing £52, so a considered purchase, but one that I'm pleased I made.
The powder is very fine and gives a lovely glow to the skin, lasting throughout the day and helping to blur and hide imperfections. It can be used alone or over foundation but does give flashback (white cast face) so not to be used if you are having your photo taken, and it is highly scented with a rose smell (like all By Terry products) so a couple of points to think about. I bought the Apricot Glow which works well on my pale, yellow undertoned skin.
