These creams have some chemical that blocks the UV with some capacity, say a factor of 50. Why can’t I apply two layers of this cream to now get a 100 factor equivalent protection?
I asked the chemist at the store and they said it’s not how it works and that the highest protection factor they have is 75 (which was super expensive).
What gives?
Edit: Thank you for those super informative answers.
No way! So like I’d be be paying exponentially more for an additional 0.6% if I brought the SPF75!
Damn.
Yeah but any power gamer loves this math because that 0.6% is still a nearly 30 percent damage reduction compared to the lower grade sun armor so you’ll be stomping those pubs that don’t persue it.
Does higher SPF cost more where you live? I just bought both 50 and 100 and they were the same price
Australia? Cause it seems that there SPF is just a marketing tactic.

Everyone knows that Societ sunscreen was the pinnacle of effectiveness and issued according to need.
