The Hidden Dangers of Sunscreen?

For years we have been told to "slip, slop, slap" in an effort to reduce our chances of getting skin cancer.

Except apparently that's no longer as safe as everyone would have you believe:

Apparently sunscreen now contains nano particles. This helps prevents a white layer being left on your skin after applying sunscreen. To be honest, I never gave the disappearance of this white layer a second thought. I was just happy that it was gone, and that I could protect myself against the sun's rays without this white layer being left behind.

Except however, this could be causing us damage without us even realising it: apparently the nano particles of zinc oxide and titanium dioxide create free radicals that have the power to destroy painted surfaces and DNA.

Except all this talk of nano particles and free radicals brings to my mind grey mist clouds roaming the land and ravaging everything it touches and leaving behind anarchists in their wake.

Not exactly something that I would associate with sunscreen that is supposed to protect us from the sun's damaging rays.

Apparently there might be some truth to the world ending this year, after all; it seems that everything we or don't do will get us killed. And usually a pretty slow and painful way.

No matter what we do, something unpleasant is going to get us.
