Clarins relies on titanium dioxide which covers a relatively small section of the UV spectrum - the 'broad spectrum' in that formulation is either chemical or lesser than the Algenist formulation which relies on a high % of zinc oxide. Zinc oxide covers most of the UV spectrum. The U.S. lacks reliable marking for the whole UV spectrum - SPF only refers to UVB rays - on some foreign origin products, you may see a PA rating which refers to UVA rays. A high SPF aptitude a significant PA rating is a good bet. I would not rely on a product using primarily titanium dioxide or a low % of zinc.

I have to disagree with another respondent, who says the Clarins "UV Plus HP Broad Spectrum SPF 40 Sunscreen Multi-Protection" is a sunblock and isn't broad spectrum - it is both sunscreen and broad spectrum, it's right there in the name. I regularly use both the Clarins and Algenist, and they are quite comparable. The Algenist is slightly lighter when going on but they both dry down nicely. The Algenist bottle is smaller, which may lead you to apply less than you should be applying if you aren't careful, and that measurement thingy on the side is pointless since the bottle is opaque (you wouldn't want a clear bottle for something which can be degraded by exposure to light anyway!). All in all, you can't go wrong with either one. Clarins is a better price, especially if you can nab one of those boxes in store that has two untinted bottles for $60, but if you are really going for the most lightweight and high SPF protection possible, don't mind having to buy a new bottle more frequently, and won't skimp on the product application because of the fact it comes in such a small bottle, Algenist is your answer.

I use Clarins and I have very pale skin. It works great for me and doesn't give give me hives (which chemical sunscreen does).
I haven't tried the Clarins but I love this it goes on smooth and I like the SPF factor

The difference is that Clarins sunblock is not broad spectrum: the only active sunblocking ingredient there is titanium dioixide which does not protect against all uva rays, that as we know, are responsible for aging.
