Over 80% of sunscreen performed below their labelled efficacy (2020)

What I find personally works is to build up a base tan. I probably did a little sunscreen application back in May but just spend a lot of time outdoors so by the time it got really sunny I had enough tan that I didn't need sunblock to not get burnt.

Even my wife who is very light and "can't tan" - I saw a picture of her when she was a lifeguard in highschool - she's bronze and probably wouldn't need sunblock either.

Obviously people make money when you buy sunscreen so the message that you don't need it doesn't get a lot of amplification.

As always, the issue is that people want things to be simple, when the reality is in nuances.

_the poison is in the dose_.

People spending hours everyday under direct sunlight are at risk.

And so does people putting sunscreen everyday, even when they don't go outside but they seat next to a window.

The amount of sunscreen you need depends on your genetics, your history with sun exposure, the place you live and the amount of time you spend under direct sunlight. There is no "sunscreen is a scam" and "life is not sustainable without sunscreen".

1. people are mad about the original topic - false claims of effacicy, when sun exposure can be very damaging and cause cancer.

2. alternatives to these sunscreens, including mechanical like hats and clothing; questions about mineral alternatives

3. wild theories like this one, where a base tan or early season burn somehow protects you. These are wrong and should be called out.
