Does the expiration date on sunblock cream actually effect performance in blocking UV rays I got a sunblock that's expired in2001it seems to work fine. does titanium dioxide degrade?

Answer 1

Titanium dioxide (T02) can degrade in the long term, but in this instance the titanium oxide should be fine, whereas the other chemicals included should be taken into consideration. I strongly suggest you spend the 5-10 quid on another bottle.
