9. Storing your makeup products in the bathroom.
Why it’s wrong: It sounds strange, but a lot of our beauty products contain natural oils and waxes in them that fluctuating temperatures in the summertime (or after a hot shower) could ruin, Strozzi says. While a lot of products are tested to hold up at room temperatures, the consistencies of some natural products, eye creams, perfumes, nail polish, facial masks, and eyeliners fare much better in cooler conditions.
Quick Fix: Move over, milk! Stick your products containing natural or organic ingredients in the fridge to prolong the shelf life and protect your makeup from being exposed to harmful temperatures. Plus, Strozzi adds that cool eye cream will help seal up your pores and feel that much more amazing on your skin when it’s hot out. Never mind the confused looks you’ll most likely get from your husband and kids—it’s all in the name of beauty!
