It's still hot out there folks.

And since we're not used to a spell of hot weather like this... ever, there are a few beauty summer hacks we never even knew existed. Little did we know, but beauty experts swear by putting certain cosmetics in the fridge during the summer months to stop them from going rancid in the heat. Yep, this is a thing. New York City-based board-certified dermatologist, Dr Kenneth Mark spoke to Hello Giggles about the benefits of using this trick. Mark revealed that the most important products to refrigerate are the ones formulated without preservatives; these can easily become rancid and contaminated when exposed to the summer heat.

Here are some products he advises to chill ASAP!

Eye creams and serums

Surprisingly, this is one you should be chilling all year round. Applying these products chilled can actually help reduce swelling and puffiness. As well as providing you with a cooling effect when applying. A necessity.

Lipstick and lipgloss

Did you know you actually should NEVER store one of these products in the car? Especially during summer as the condensed heat can actually cause them to change consistency and separate. This, in turn, makes them of a poorer quality and who wants to pay €20 for a MAC lipstick if you're not getting value for money?

Face mask

Storing face masks in the fridge is actually the only one of these things I do. Be it a sheet mask or a mask tub, these feel x1000 times better when they are cool. Nothing feels nicer than popping this on post stressful work day. Plus, leaving these in hot conditions will once again cause mask tubs to separate and unfortunately, you will end up chucking it away, not good.

Facial oil

According to Hello Giggles, UV light can actually accelerate the breakdown of facial oils. Storing this product in the fridge will help it to remain uncompromised from damaging sunlight exposure.

Teeth whitening products

To keep your pearly whites, white - teeth whitening products should be kept in the fridge and away from the heat as the climate begins to rise. Due to the instability of actives in the formulas, the trick is to keep these chilled. Other notable products include face mists and nail polishes. And if you're like me, and you can't afford to fork out for a full, new selection of beauty products come autumn, do yourself a favour and preserve them now while you can. Y'all can thank me later.
