Here's a quick look to show off Smashbox's O-Glow blusher and O-Gloss (gloss), two seminal products from the Los Angeles brand. Both of them go on clear but react once on the skin to create a pink flush. The brand blurb says they react with the moisture in your skin to create a shade that's spot-on for your particular cheeks or lips.
O-Glow was originally released by Smashbox a few years back and it created a buzz thanks to its unusual colour-changing action. It's a smooth, silicone-rich gel (think Smashbox primers) that comes in a squeezy tube with a screw cap. A small dot on each cheek is plenty to create a natural colour effect on my fair skin, and it blends hyper-smoothly thanks to its texture. However, despite its adaptive powers, I've heard that it doesn't pack much punch on darker skin tones (your experiences with this are very welcome). You get 15ml in a full-size tube, which is quite generous when you compare it to your typical 5-10 gramme pan of blush.
The O-Gloss was released as a flanker to O-Glow following the blush's popularity. I think I actually like this even more than the blush. It's got a very balm-like texture and manages to be quite thick and moisturising without feeling sticky or tacky. It creates an extremely wearable pink tint that makes me feel a slight bit more presentable in the mornings, and I find it does the job of lip-balm. The squeezy tube has a slanted applicator, making it very easy to put on. You get 10ml in a tube - about standard for a gloss.
Smashbox O-Glow costs £21 and O-Gloss costs £16. You can buy both online at Boots
