How do I avoid these?
Largely by avoiding waterproof or water resistant skincare products such as sunscreen and makeup. Also avoid using nonstick cookware.

I think the key there was "water resistant", suggesting the substance is used in the additives to make it resist getting rinsed off.
It's not a required ingredient for sunscreen to work, it's just to make it more water resistant (it stays on your skin longer) so those chemicals are typically used in sunscreen that's marked for water/sports applications. You can buy PFAS free sunscreen too
Use the ThinkSport brand.
