You heard it here first - make-up that glows under UV light is set to be a trend for summer.
This morning one brand showed me a top secret product that glows under UV light (launching end of April), and then at lunchtime I headed to the Stila's summer launch where lo and behold they are launching After Glow Lip Color, £12.
It's a colourful crayon that comes in six chic shades by day, that by night, under UV light, is transformed into glowing neon - ideal for summer festivals and nights out clubbing.
I love the punchy colour (Festive Fuchsia), it lasts really well on my lips and isn't drying.
And here I am demonstrating the UV effect with a torch in the office, but you get the idea...
Impressive - and fun for a party. But what's great is that 99 percent of the time this is just a regular, but pretty awesome, lip crayon.
