Sweaty skin, cakey cheeks, smudgy under-eyes: we all know the pains of trying to apply make-up in hot weather. You'll leave the house looking perfectly glam, and after an hour of travelling and standing in the sun, find your face resembles a half-melted wax figure from Madame Tussauds.
If you can relate, it's likely you're making a few common make-up mishaps. Don't feel bad, we were too – at least until we spoke to Saffron Hughes, professional MUA at FalseEyelashes.co.uk.
Hughes set us straight by highlighting the six biggest errors people make when it comes to heatwave make-up, and her top tips on how to avoid them. From piling on the powder to skipping setting spray, here are the mistakes to avoid if you want to stay looking hot in the heat.
Using the wrong type of primer
Primers are one of the least understood make-up products, and many people think wearing any – regardless of skin type and formula – is good enough. But, as Hughes points out, some primers are actually detrimental to make-up's staying power when it's warm outside.
'Oil-based primers can make your make-up feel like it's sliding off by lunchtime,' Hughes says. 'They're often too rich for warm weather, and can actually leave your skin looking shinier than intended.'
'I always recommend a silicone-based primer in the summer. It grips your make-up better and gives a smoother, more matte finish – especially when sweaty skin is producing more oil anyway. If you know your skin suits oil-based primers, opt for a lightweight formula that won't make your face look greasier.'
Overlooking waterproof formulas
We know it seems extra to have a 'summer' and 'winter' foundation, but the truth is it's worth investing in a longer-lasting waterproof formula that works harder when it's hot.
'Regular foundation might look fine in the morning, but once the heat kicks in, it can start to break down fast,' Hughes says. 'You really want to look for long-wear or waterproof on the label.
'These formulas are built to last through sweat, humidity, and the works. It sounds obvious, but a lot of people skip this step and end up wondering why their base has disappeared by midday.'
It's not just your foundation that needs a change-up. 'The same goes for investing in waterproof eye products,' Hughes advises. 'If you're going to be out for hours, especially in the sun, your make-up needs to hold up without constant touch-ups.'
Applying your base in one layer
We're all guilty of slathering foundation on with our hands, usually when we're running late for work and can't locate a clean brush. But according to Hughes, it's one of the simplest reasons your make-up has zero staying power.
'Piling on product rarely works well in warm weather,' Hughes explains. 'It's much better to apply your foundation in thin layers and build gradually, using a damp beauty sponge. Let each layer set before adding more. That way, you avoid caking and help your make-up last without separating or settling.'
'This approach also allows your skin to breathe, which is key to avoiding that heavy, 'melted' look later in the day.'
Overdoing it with powder
'A bit of translucent or setting powder is essential in summer,' Hughes says, 'as it helps absorb oil and keeps your make-up in place.'
But use too much product and it can quickly backfire. 'Powder tends to cling to sweat or settle into fine lines,' Hughes says, 'especially in the sun, which can leave your skin looking cakey or textured.'
So how can you remedy that weird cakey look that comes with too much powder? Hughes recommends using a light hand and focusing on the T-zone. 'Apply with a small fluffy brush rather than a puff or sponge,' she says, 'and only where you actually need it.'
Skipping setting spray
Lots of us imagine setting spray is an unnecessary cost – after all, if we've already spent extra on waterproof formulas, what's the need? But ask any good MUA like Hughes, and they'll tell you in the summer months, it's one of the most important products in your make-up bag.
'A good setting spray works like a veil,' Hughes says, 'helping to keep products in place even when your skin starts to warm up. Some formulas even help to cool and refresh the skin, which can make a huge difference on a hot day.'
'Look for sprays that specifically mention staying power or sweat-resistance, and let it dry naturally after spritzing.'
Sticking to your usual mascara and eyeliner
We know it's expensive to seasonally swap out your make-up items. But according to Hughes: 'Non-waterproof mascara and eyeliner just don't hold up in summer, especially if you're sweating or spending time outside. They're far more likely to smudge or transfer, which can undo your whole eye look.'
She suggests switching to waterproof formulas during warmer months and, for added staying power, layering products. 'I often recommend applying false lashes using a strong lash adhesive for extra definition. It gives a cleaner finish and holds much better in the heat.'
