Does sunscreen expire?i hav bottles from last year & da year b4 dat..but ders no expiration d8 or best b4..?

i really dont know but i think that they expire like most of the products for example i use one like 2 weeks ago that i buyed like 3 years before and it cause me a riaction so, yes i think that they expired but i think that your bottles from the last year are ok

yes sunscreen does expire...i bought a bottle that had no date on it...but it was from the year before...and its turning weird already..like all bad..so i threw it away...so yes they do expire...usually after a year..and if its over that...then its not gonna work no matter how much sunscreen you put on you...you are still gonna get sunburned..

Yes sunscreen does breakdown and go bad. I had one that turned from white to light brown. Sometimes after awhile it gets real liquidy. If so then get another bottle.

Sunscreen does expire! I think it's good for about 4 years... make sure you have UVA and UVB protection, avoid pyrimidine dimerization! I have been told that that zinc oxide never goes bad... but never say never.

The expiration is usually on the bottom of the bottle. They do expire, usually in about 1.5 to 2 years from when you purchase.

Sunscreen does not expire, but if it really is that old, then maybe you should put it on more often. It just isn't as potent as a new bottle would be, but it still works. Trust me, if anyone would know, it would be me.
