How safe sunscreen really is?

[Jack.77]

So I had a bad sun burn the other week and i’ve since been regularly using factor 50 but despite the two brands being the more expensive types I seem to be getting a few spots since using them
I’m not convinced most of the market leading brands are that safe .reading online The usual argument is that any risk is greatly outweighed by the risk of potentially developing skin cancer but I’ve been wondering if this risk is potentially higher than people think .and why the formula hasn’t just been altered to be more natural with less chemicals
it’s already mentioned on the breast cancer .org website it can interfere with hormones causing cancer.
‘’While chemicals can protect us from the sun's harmful ultraviolet rays, research strongly suggests that at certain exposure levels, some of the chemicals in some sunscreen products may cause cancer in people’’

You need to make a choice. Sunscreen might have some chemicals in it that could cause cancer, 1 in 2 of us will get cancer at some point, how would you know the suncreen caused it?

The best solution is to avoid the sun altogether. Stay in shade where you can and keep covered when you can't.

All I know is out of all cancers, malignant melanoma is one of the nastiest. It'll spread to your brain and lymphatic system in no time and is directly linked to UV exposure.

Yes it would probably be difficult to proof if a cancer was caused by using it .saying that It’s not impossible to make the direct link .With my work at the moment I’m in direct sun a lot so am caked in the stuff again today -

I burn easily on my bald head...but I apply SPF30 every morning and it lasts all day...you don't need to go mad with the stuff like some people do, or keep re-applying every hour. I do think some people overdo it.
I use the Nivia stuff which is the best IMO.
Obviously, that's just my experience. This is not medical advice.

Does it not just come off with sweat .today I applied it 3 times in total as it just seems to come off .
That was Nivea f50 .started burning on neck prior to 3rd go
