I think it’s helped me. I’m the only one in my family without skin cancer, and I’ve worn sunscreen.
I don’t go out in the sun as much as they did, but I was also more diligent about sunscreen.
Unfortunately for me, I got overexposed multiple times as a child. I wear sunscreen and stay out of the sun as much as possible now, but they claim that early exposure will eventually haunt you.
Fortunately nothing so far.
