If you look into advice from non-manufacturers (some other groups who are a bit less biased) it's widely recommended to max out at SPF 30, because any higher means sunscreen is harder to re-apply (meaning psychologically you are likely to not re-apply as often as needed) and also because it really doesn't make a difference unless you are ultra sensitive and have some kind of skin condition.

> it's widely recommended to max out at SPF 30,

You're going to have to bring some receipts for a claim like that. I have never seen such a recommendation, ever.

I can't remember where I first heard it but here's a few links.

https://www.ewg.org/sunscreen/report/whats-wrong-with-high-s...

https://www.mdacne.com/article/why-spf-30-is-better-than-spf...

This one (https://www.skincancer.org/blog/ask-the-expert-does-a-high-s...) doesn't directly say its better or worse, but alludes to the idea that when you combine the various factors there's definite cons to SPF 50.

Potentially I slightly overstated, what I intended to say was "there's clear reasons why SPF 30 would be preferable in many/most cases". If you are a pale white person who is hiking through the Sahara with no hat SPF 50 might be the way to go.

		First link is some political organisation. Second link is a company that sells SPF 30 sunscreen. Third link doesn't even say what you're claiming.

Using higher SPF can help cover for thin application
