Blue makeup might conjure up all kinds of '80s throwback imagery, but trust me, what I'm about to say isn't as bizarrio as it may sound. Blue lip gloss is good. Not bad, but good. Maybe not on its own, agreed — it's not exactly the most flattering hue. But layered over your favourite lipstick or coloured gloss it works wonders. Just as blue mascara makes the whites of your eyes pop and look brighter, blue lip gloss can make teeth look whiter. LOVE. Since it's sheer, it can be layered over any colour for a subtle effect. It'll also tame down any unwanted warmth from your liner or lipstick. And if you get a glittery version, it can help to make your lips look fuller, too. It's like the gift that just keeps on giving. 'Tis one ultra cool hue. Get it? Tee hee.
