it's that time of year again! just realised the full 3 bottles of sunscreen lotion (all different SPF's) that I bought last summer "expired" a couple of months ago. Are they still effective (a lot, somewhat, or not at all)? :confused:

This came from Cosmo:
Q Will my leftover sunscreen from last year still be effective?
A Check to see if your bottle of sunscreen is stamped with an expiration date. If you don't see a date, the rule of thumb is that the active ingredients in sunscreen (like zinc, titanium dioxide and Parsol 1789) should remain stable and effective for about three years, according to David Leffell, M.D., professor of dermatology at Yale School of Medicine. But if it smells funny, feels lumpy or has a bizarro color, dump it. To keep your sunscreen as close to new as possible, store it in a dry spot at room temperature with the lid tightly fastened

Don't really know, but I'd say "somewhat". BTW, way did you buy three bottles before using up the first one? :D
