Unfortunately Health Canada doesn’t require UVAPF testing, so it’s not clear what the actual UVA protection is.
Ombrelle does contain 3 sunscreens with UVA coverage, but Health Canada has limited how much can be used:
Drometrizole Trisiloxane (Mexoryl® XL) 2.5%
Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl® SX) 0.5%
You do raise a good point though, and it’s better to be sure than to assume. I’ll be switching to a European sunscreen, Bioderma Photoderm MAX SPF 50+ with a tested UVAPF of 42.
Having seen the photodamage on my face now, I think the extra hassle, shipping, and price is worth it.
Especially after you consider that UVA (which UVAPF is a protection factor for) is mainly responsible for increased pigmentation, as well as cell and DNA damage.
