I don't ever see low number tanning cream these days anywhere, in fact. Mostly see only 30, 40 and 100. My 30 year old stash of 8 & 15 is finally running out and I'm going to have to break down and buy some. Thanks!

I wouldn’t bother. You might have not been using sunscreen anyway for the past 27 years.

Is sunscreen from last year still good? When does sunscreen expire?

The U.S. Food and Drug Administration requires that sunscreen remain at its original strength for at least three years. That means you can use leftover sunscreen from one year to the next.

Some sunscreens include an expiration date — the date when they're no longer effective. Throw out sunscreen that is past its expiration date. If you get sunscreen that doesn't have an expiration date, write the date you bought it on the bottle. Throw out the bottle when three years have passed since that date.

I appreciate the importance of using sunscreen. My mother had skin cancer on the end of her nose and had it removed. A friend who has Celtic heritage had skin cancer removed.

I used SPF 15 for a couple of years back when that was the strongest available, but I realized that I was sweating it off quickly and not reapplying. I have been fortunate so far after decades of enjoying outdoor activities and remaining cancer-free.

When we moved here, we brought a bunch with us. It has since expired, and we are being careful just to not be out during the bad times. We still spend about 3 hours on the beach and water daily but early.

Question: Where do you find the most economical low-number tanning cream or sun-block?
