Even if that was true (it's not, long term exposure to UV rays from the sun causes skin cancer), sun damage is still a thing. I live in a super sunny country, I don't want my skin to look like worn out leather by the time I'm 50. I'm putting on sunscreen every morning. SPF50.

Also the Andrew Huberman guy, basically a "science based" Joe Rogan knockoff, advised against putting on sunscreen because he thinks that the chemicals in it are more harmful than the damage caused by the sun. For some reason health and fitness gurus are going hard against sunscreen at the moment. I have no idea why they are doing this. One of the easiest ways to stay looking younger is to use sunscreen every day lol. Probably the easiest health and beauty "biohack" that exists. 30 seconds of work a day which consists of applying a cheap cream to your face and exposed skin, so you look 15-20 years younger when you're 60. You'd think health and fitness gurus would promote the hell out of this.
