Has anyone come across this new suncreen? there website states " 37% of the sun’s rays are damaging to the skin. Current sun screens that you know and buy, only protect against UV-A and UV-B. That means they only protect you against 7% of those rays. By protecting against Infrared-A as well, Ladival offers protection against four times more of the sun’s damaging rays."

Ive searched the website but theres no information on how this sunscreen actually works and offers 4 times more protection against IFRARED.

 

Have we missing out by using our European sunscreens?!?

You can find papers that show undesirable changes in skin cells from in vitro experiments where isolated cells are exposed to roughly ten times the level of IR that you would get from the sun at high noon on a clear day.  The question I would ask is how relevant is such an experiment to living skin getting real-world levels of exposure?   Another question I'd want to ask would be: "Does their IR filter in fact filter out the IR as it claims?"  Has there been any testing of this product in humans, and is their any measurable change in human skin from the use of this sunscreen?  My guess is that it's more of a marketing ploy than anything else, but I could be swayed by evidence of utility.

Thank you for a great reply. Was being to panic :P clever marketing though!

I use it, there was a discount on boots online.
It's quite good subjectively, it makes your face look white, and is easy to apply. Makes your skin a bit shiny though (especially after a while, or is it sweat?), maybe more than other sunscreens I have tried.
