The difference between SPF 60 and 100 is like 1.1% better UV blocking, anything over SPF 50 is in a practical sense nearly useless.
For instance SPF 30 blocks 97% of UVB rays, is it worth paying more and slathering more potentially harmful (to the environment) compounds on your skin for 98% blocking? I think not.
From another thing I read, people have a tendency to not apply enough sunscreen or apply it correctly. I’m sure if everyone did it perfectly it wouldn’t matter. All I know is anecdotally, when I switched to 100 I stopped getting sunburns, and I have been in situations with people who used their own lower spf, got a little burned still, and I came out of it pale white.
The price might be higher, but a quick look on Amazon and I’m seeing more than spf affecting that. The brand I buy is about 1.80 (usd) per ounce, and i see other brands with less spf for more. I see other brands with the same spf for less, and it seems like it’s between ~1.10 per ounce to ~2.80 per ounce so I’m not really bothered by my price. I don’t know anything about the environmental differences between spf so I won’t comment on that.

Seems like in real world use it makes a difference.

The average person should almost certainly not be using it, but maybe it would make the difference for extremely sun sensitive people.
If someone is that sensitive to sun they should start picking up fashion tips from the Bedouin.
what if your skin has a hit point system and that 1% difference is the breaking point of sunburn
They’ve cracked the code…
