I have a good habit of discarding a mascara every 3 months.
I used to put a date on the tube using a sharpie but now just set a reminder on my phone.
While it is a nice hygienic practice, I don't think I could do the same so easily with higher-end ones. Which is why I usually stick with drugstore mascaras.
I think L'Oreal makes nice mascaras, and The classic Voluminous waterproof is my all time favorite. I always stock up on them whenever I spot a good sale.
This doesn't stop me from trying new ones, of course. Who can resist those new mascara ads with CGI and falsies?
I was super excited when L'Oreal brought out the new Voluminous Butterfly Lash Out Mascara but waited patiently until the waterproof version was available.
