Should cosmetics be refrigerated?

The answer is X! Cosmetics must be stored and used according to their intended purpose and usage instructions to ensure they are most suitable for your skin and to properly utilize their shelf life. If you look at the back of a cosmetic product, you will see instructions to avoid direct sunlight and store it in a cool place, so many of you might think, "Then wouldn't it be even better to store it in the refrigerator?"... but actually, this is also the wrong method!

​

Since refrigerators maintain temperatures much lower than room temperature, they can cause cosmetics designed for room-temperature storage to spoil more quickly. Additionally, cosmetics that become too cold can irritate the skin, and depending on the ingredients, their absorption rate may decrease.

​

Don't forget the fact that cosmetics are absorbed more effectively the closer their temperature is to your body temperature!! :)
