The Beauty Of Storing Products In The Fridge
Cristina Samuels, co-founder and co-creator of MODE cosmetics, said the best thing you can do for your lipsticks is keep them cold — and the colder the better. "Freezing your lipstick locks in all its freshness and helps prevent the beneficial and delicate natural oils and extracts from going rancid, helping extend its shelf life," she said.
"Remember, heat is lipstick's enemy. I have advised women for years to store their extra lipsticks in the freezer and just pop one out the night before or a couple hours before you plan on using it, [allow] it to come to room temperature and your lipstick is ready!" she explained.
