Do you believe them? I don't. Some research says the nanoparticles can penetrate the outer "dead" layer, some says they can't. They definitely can when there's broken skin, even if it's just a tiny bit you wouldn't even notice.
|Ok..so the sunscreen isn't causing cancer, but rather people think they are safe from risk (since they aren't getting burned) and get overexposed and thus develop melanoma. Do I have that right?
Unfortunately, no. Look up nanoparticles. They've never undergone any sort of official safety testing. They accumulate in the environment. Some of them kill plants, animals and bacteria. And we have some evidence they can cause
skin cancer through the formation of free radicals, which damage DNA. Most sunscreens nowadays contain nanoparticles. If you are going to put on sunscreen, you need to find one that protects against both UVA and
UVB and that does not contain nanoparticles
. Otherwise, you're either not preventing cancer because you aren't protecting against UVA and UVB, or you're using an unproven product that might cause the exact problems you're hoping to avoid.
Oh, and aside from all of that, there is also evidence that applying sunscreen all the time increases the risk of cellular damage the times you forget. Basically, it's good to get a little sun now and then - it can prevent
