Skincare products are susceptible to changes in temperature, making a hot and humid bathroom a less than ideal spot to keep your serums and moisturisers.

“When you shower, your bathroom heats up significantly and this can spell disaster for your skincare products. The rapid heating and cooling that takes place can fundamentally change the texture of a product and make it more watery – ultimately diluting its effectiveness,” Hulme explains.

“To make sure you are getting the most out of your skincare, you should really look to store it outside the bathroom and move products before each use. While it might seem like a lot more effort, storing your skincare in a more stable environment can help to prevent your products from showing signs of expiry well before they should.”
