This article leaves me with a lot of questions. As I understand it, SPF labels in the US have to apply to both UVA and UVB. They tried labels specific to each but decided that they were too confusing. Next, you don't need more than about SPF 35 to get appropriate protection from skin cancer. SPF rating higher than that offer only marginally more protection. Lastly, how are these "chemical" sun screens blocking UV. If it's not physically blocking the light, are they somehow changing the spectrum of the light so that it is not harmful? So, other than this guy who has spent $18B to try to sell his product in the US gunning for it, what is the advantage of the newer "chemical"? Do they last longer, cost less, have other functions for health and beauty? Are they generally easier to use?
Here is just one of the many videos I could find describing the difference between physical and chemical sunscreens. In short, both, to an extent the physical kind included, absorb and transform it into heat. Consumers can get chemical kinds that don't leave a white cast, offer varying levels of protection, dry fairly quickly, and are easy to apply under makeup if that's a concern. I know because I've used a couple brands with these things in mind and have loved them for years.
