I found two old sunblocks (Banana Boat) in my room that I've never used. I bought them five years ago and I'm sure they've been in the heat many times during summer.

Would they still be effective after five years even after it's been in the heat? Should I throw them out? How long can a sunblock last?

Sunblock expires one year after you open it, I think. There should be an expiration date on the bottle.

Usually sunblock is only effective for use after one year of opening it.
I would suggest throwing your five year old ones out because they won't really protect you

Definitely throw it out. I think most sunblocks have a one-year shelf life.

Why even bother with it? Just buy some new ones~ They don't cost that much
and they usually have expiry dates on em.

Plus, your skin can also get an allergic reaction to that old of a sunblock.
At least, my dad broke out into a bad rash after using one that was 2 years old.

the answer is: no

the effectiveness decreases every year. it would be better just to buy a new one instead of risking sun damage~
