When applying bronzer, there's a very fine line between looking perfectly glowing and looking overcooked. That's where the MAC Lustre Drops (£18) come in handy. The creamy, semiopaque, nonglittery formula is part bronzer/part highlighter for a natural-looking finish. A mix of pink, gold, and copper tones, this complexion enhancer blends beautifully into any skin tone. Just dab a bit under your brows, down the nose, on the cheekbones, and along your Cupid's bow. That's all it takes to achieve that just-off-the-beach luminosity — even if you're trapped in city smog.
