Wondering about that mini fridge you spotted on top of your friend’s vanity? No, it isn’t for storing snacks for those late-night food cravings – it’s for beauty products. With so many influencers showing off chic mini fridges on Instagram lately, you might be wondering whether you should partake in the trend. Aside from being a pleasing addition to your bedroom or bathroom, beauty fridges – as well as just regular kitchen fridges – keep your products cool and away from sunlight, which can aid their longevity and effectiveness. There are also a number of short-term benefits of applying cold products to your skin, especially in the mornings. But not all beauty products should be kept in the fridge, as cool temperatures can be detrimental to some formulations and ingredients. Here are five types of products that you can keep in the fridge, and one that you shouldn’t. Eye creams and moisturisers If you’re familiar with the cold-spoon technique – depuffing eyes by pressing cold spoons on them – you’ll also enjoy using fridge-cold eye cream in the mornings. Putting on cold cream in the eye area can constrict blood vessels and therefore minimise puffiness and any swelling that occurred while you were asleep. The same goes for regular moisturisers, for which the cold temperature can enhance firming and reduce inflammation. Sheet masks Similarly, face masks can benefit from being stored in the fridge, as the resulting cooling effect can help soothe your skin, reduce redness and calm any irritation in the short-term. Plus, the chilly sensation also makes the masking experience particularly refreshing – perfect for the morning or after a long day. Clean formulas Many all-natural, clean beauty products tend to forego preservatives in their formulations, but that means their shelf life may not be as long as those with chemical ingredients like parabens . Storing clean formulas in the fridge can extend their longevity, as they won’t be as perishable if stored under consistent, cool temperatures. Retinol and vitamin C products Make sure to leave some space in your fridge for your retinol and vitamin C skincare, as these antioxidants can degrade much quicker and become unstable when exposed to heat and sunlight. Storing these products in the fridge keeps the formulas stable and helps with preservation. Facial rollers and other tools While jade and rose quartz facial rollers and gua sha tools stay naturally cold, it doesn’t hurt to keep them in the fridge. Using these tools promotes lymphatic drainage, which guides the fluids in your face and can result in tighter-looking skin. Acne medication Since acne medications have specific chemical make-up, some benefit from being stored in the fridge. “Certain prescription medications, such as compound medication that we as dermatologists use all the time for our patients, need to be kept in the fridge in order to be stable,” dermatologist Dr Martha Viera told the Byrdie website. “Also, some products that can help with certain conditions such as rosacea, itching or sensitive skin can benefit from being used cold since it creates an anti-inflammatory and vasoconstrictive effect.” Do your skincare products contain ‘good’ or ‘bad’ alcohol? Experts explain Don’t refrigerate: Make-up While you certainly can stick a melting lipstick in the fridge to resolidify its formula and bullet shape, make sure not to leave it – and other make-up products – in the fridge. Oils and balms, which are present in many make-up formulas, can either separate or become too solid in the fridge, so storing them there won’t help with application or longevity.
