What is a beauty fridge? It's a tiny refrigerator in which to store your skincare products. The purpose of a beauty fridge is to keep skincare formulas at a chilled and stable temperature, ensuring that the formulas remain stable for the duration of their shelf life. Because beauty fridges are quite compact, they can be easily tucked away in your bathroom or near your makeup station. The concept is a lovely one. Of course, if your beauty shelf is in a temperature-controlled space, there's not much reason to purchase an item like this. On the other hand, if your space has severe fluctuations in temperature, then this could be a nifty way to keep your skincare products in a temperature-controlled space.
