After my dermatologist removed a mole from my leg this past February, she reminded me that sunscreen should be replaced every year. Being the quasi-frugal girl that I am, I've always ignored this tip. I've been known to cut squeeze bottles of lotion, sunscreen and makeup open just to scrape the last little bit out. I've rarely managed to use a entire tube of sunscreen a summer, so I typically save them.
But now that I've had a dysplastic mole (and the scar to match - goodbye, shorts), I'm changing my tune. On my last trip to Target, I got new sunscreen and I tossed my old stash when I got home. To help me remember to toss this bottle later, I've written "2010" on it with a Sharpie. Come summer of 2011, this bottle will be going in the trash. Sometimes, it's better to be safe that to save a few bucks!
