I have a pricey Lancôme mascara coming in the mail today but have to be gone til late and wondering if the cold ( below freezing) temperature will ruin my mascara out in the mailbox? TIA for any advice

I wouldn't think extreme cold would adversely affect a mascara.  My problem is the opposite.  I have to avoid having beauty products come in the summer because they'll "cook" in my mailbox for 5-6 hours before I get home!

Neither extreme cold or heat is good for cosmetics. But heat is far worse because it can cause chemicals to change, react within a container with other things or promote microbial growth. Freezing, otoh, will slow these things down but in the process may cause some chemicals to precipitate and become inhomogenous (clumpy).

@cactusjack I'd wait until it's room temperature before using it.
