We went boating last weekend with it being around 80 and sunny........is it safe to use sunscreen products from last summer?

I'm no scientist or expert. But, I have not had a problem using sunscreen from the previous year. In fact, I have a backup in my tackle box that is probably several years old. I have used it on my face when fishing and i didn't burn.

They won't hurt you, but they may not work as well or at all.
I remember reading that the manufacturers recomened you replace it each year.
I replace mine every summer, cheap insurance.

HEY NORT, I THINK A NEW BOTTLE MIGHT BE ONLY BE A COUPLE BUCKS! (CHECK EXPIRATION DATE)

Yep, just to back up what iggy said. They do have an expiration date on them, that may cause them to be ineffective.

80 degrees, yeah wish I was concerned less w/ fuel line freeze up and more w/ if I needed fresh sunscreen!!!

Do you even need sunsceen in Calf. ? I didn't know UV rays could get through smog.

Your a funny guy.. The groundhog saw his shadow yesterday, so we only have six more weeks

Nort, are you serious or are you just trying to rub in the fact that it's 25 degrees at LOTO this morning?
Oh yeah, sun tan lotion can go bad and not work. Found that out the hard way.

I can't believe you guys could of possibly taken him seriously I have some property that involves a bridge or two if you are interested

Nort, I think that after it's a year old it's only safe to stick it U#$ your #$# Windy and very cold today not to mention the snow. Enjoy the sunshine and the warmth you are lucky to have the options to go boating this time of year

Thats the great thing about being able to boat at this time of year... who needs sunscreen??? We went out sunday and none was needed!
