Hi, previous Anon here. Very nice graphs, and glad to hear you’re switching to something better =)

…I personally reference Skinacea’s UV filters chart and always pick sunscreens with zinc oxide and/or tinosorb. If the Bioderma is too expensive, there are definitely much cheaper Japanese and European sunscreens with great protection out there! Probably same amount of hassle in terms of shipping though

Thanks for writing back 🙂

Tinosorb S, M and Mexoryl SX, XL seem to have pretty similar protection. Though I haven’t looked at the numbers stringently I would say Tinosorbs tend to offer more absorbance (though I don’t have the concentrations)



(It’s not really fair to compare Mexoryl XL with Tinosorb S, it would have been better to compare Mexoryl XL with Tinosorb M as the curves are more similar)

I’m going to see if I can find more graphs with labelled axes for different sunscreens and actually graph them all together 🙂

Problem is, the amount used is still limited by Health Canada – not to mention companies choosing to manufacture with these sunscreens have to pay an additional fee. It’s worse in the US as their use is banned.

I’m pretty happy with the Bioderma’s texture, it’s a bit oily on me because of the dimethicone, and makes me shiny by the end of the day, but it’s a small price to pay.

While I do like the texture of Asian sunscreens, I don’t like the PA++++ system, as you can’t tell the difference between say, a UVAPF 20 and a UVAPF 16, as they’d both be the maximum PA++++.
