If you choose to go bold with makeup, you walk a fine line between making an impact and being remembered for the wrong reasons. But ill-applied red lipstick isn't the only offender.
So are lurid nails and too much mascara.
Here's why ...
Bold nails: They may still be fashionable but I'm not the only one who thinks black nails look like they've been bashed with a hammer. Bonus bad points if they are chipped. Ditto over-bright blue, yellow and glittery nails (of any colour). In summer, glossy and beautifully applied, black, blue, yellow and sparkly can be gorgeous. In the depths of winter you risk being compared with a child.
Clumpy mascara: Mascara should be thick and noticeable - that's the whole point. But if it's so thick it's sticking your lashes together and falling in flakes on your face, it's too obvious. (Ditto lash extensions in need of re-doing since they tend to stick out at odd angles.)
Smudged lipstick: Bold lipstick really needs to be checked every time you make a pit-stop. If you have an exemplary bladder, invest in a compact - there's no shame in reapplying at your desk.
Foundation marks: Getting the colour of your concealer and foundation right is beauty 101. Remember, too, that even sun-screened faces can change colour in the summer.
Melting eye makeup: Not such a problem in winter, but summer heat can melt shadow and mascara into an inky mess. If you're affected (it tends to happen more if you have oily skin), switch to waterproof formulas, even if you're not going near water.

"My absolute go-to products are my Pure Shade Brightening SPF50+ Sunblock and One Truth 818 Anti-Ageing Serum. Pure Shade is gentle, totally natural but extremely effective and it lightens my sunspots, which is an added bonus. The 818 Serum is amazing for the texture of my skin. I get comments all the time about my skin's luminosity and I put it down to this product. Say no more."
