      Lotion is good for the first coat, but the spray is so much easier to apply when you’re already sweaty and sand is everywhere.

      I used to have that problem. I switched to 30 spf and don’t get burned anymore. I can’t really explain it, but my theory is that 50+ is marketing BS and doesn’t actually do anything. Or it could be that Banana Boat brand just really sucks and Hawaiian is more like lotion so it actually stays on my skin and also moisturizes, which probably helps because dry skin = gonna get burned.

        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.

          I used to think the same thing, but the thing is we don’t care about the energy that goes into the sunscreen, we care about the remaining percent that goes into the skin. If you go from a sunscreen that absorbs 98% of the sun’s energy to one that absorbs 99% you are halving the amount of energy your skin is exposed to.

          If you’re still getting burned with 98% absorption, then increasing that number by 1% would actually make a huge difference. And that’s without even considering things like having a safety margin for improper application.

          Seems like in real world use it makes a difference.

          https://www.sciencedirect.com/science/article/abs/pii/S0190962219327550

          https://pubmed.ncbi.nlm.nih.gov/29291958/

          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.

          what if your skin has a hit point system and that 1% difference is the breaking point of sunburn

          The average person should almost certainly not be using it, but maybe it would make the difference for extremely sun sensitive people.
