I use Walmart brand sunscreen before going outside on a hot sunny day. For decades I used to get the worst itchy sun rash - but only on my arms during summer, so about 5 or 6 years ago I broke down and tried the sunscreen and  for me it works like a dream.   

You want a sunscreen that doesn’t cause cancer.  It may work great but will it cause skin cancer later on.

Zinc is an important ingredient. 

Check out your sunscreen brand on EWG.org  website.

What ingredients should I be looking for/against?

This summer, my husband didn’t use any on his face and as so much better.   

I had bought him Badger brand.

What?

If you want to make a boomer uncomfortable refuse to put sunscreen on your children. 

 Or tell them if you get cancer you don't want costly treatments like chemo.

Over the years I've seen a conspiracy theory that state that sunscreen is actually bad for you and causes caner. I've never bothered to look into this. Has anyone else heard of this? And does it have any merit or is it just bogus?

There are three types of rays, UV-A, UV-B, and UV-C. Sunscreens didn't used to be "full spectrum" but only blocked one kind of rays, usually UV-A since this allowed tanning without burning. The other type(s) of radiation that did get in was what caused the cancer though it didn't cause the sunburn, so people assumed they were safe. (That's the general problem with interventions that treat symptoms instead of the risk itself.) The manufacturers figured this out and now almost everything is "full spectrum" blockage. Yet the ingredients aren't exactly good for you either.

Another problem is that UV-B absorption is what makes the body produce Vitamin D naturally, and a Vitamin D deficiency itself is linked to many health risks including cancer.

Solution is to get a moderate amount of sun regularly since it's good for both physical health and mood, and to cover up long before there's any chance of sunburn.

Skin cancer trivia: Back in the day when men were men and women were women, skin cancer for men was usually on the left arm and the left side of the face, and skin cancer for women was usually on the right arm and the right side of the face.

Guess why? (Hint: it's the opposite side for Britain and Australia.)

Yeah, this right here is why I believe they're pushing sunscreen like it's going out of style.  Vitamin D shows very powerful activity against cancer and viruses.  They want people to keep getting cancer.  So, far from preventing cancer, sunscreens have almost certainly contributed to the dramatic increases in cancer rates.
