I'm not convinced about sunscreen

Or more specifically the need to reapply frequently/every 2 hours.

I am very careful with my skin, it's very fair and can burn within minutes in strong sun.

However, I find a decent high factor sunscreen, applied thoroughly in the morning protects me all day. For example, I'm just back from a sunny outdoor activity holiday. Out in the sunshine from 9am-6pm for 6 days.

I did my water resistant factor 30 suncream before breakfast every day, whilst getting dressed. Then nothing else all day. The activities involved getting hot and sweaty but not going in water. (I would reapply after swimming).

Anyway, I had a great time and my skin is exactly the same colour as it was before. I don't even have the faintest mark where my watch was.

Suncream is essential, I wouldn't dream of being outside without it in summer, but the need to reappply so frequently is driven by scientific research funded by the industry itself and more in their interests than ours?

I have 2 BCC on my leg that I'm waiting to have removed, most likely from sizzling in the sun in the 80s, nowadays I go out dressed from head to toe in clothes if it's sunny, and apply plenty of cream.

Go under a uv light after a few hours and you will see

That's good. Sunlight plays a potentially useful role in moderating blood pressure so if you get very little then it's important to keep an eye on BP as you do.

TBH everyone over 30 needs to keep an eye on their blood pressure anyway.
