thx to everyone who recommended the lab muffin beauty blog, I am learning lots from it and the INCI decoder app! the tough thing is that all this stuff is about the effect various ingredients have on normal people with normal skin and not a lot about how specific ingredients interact with extremely sensitive/dry/allergic skin. they're also always saying "this is fearmongering bc this won't cause any problems for you unless you have unusual sensitivities" and it's like well I don't wish to spread fearmongering but could you maybe address what the impact is on those of us who DO have unusual sensitivities, lol? we exist and we would like some guidance from the science minded people but they seem largely to not be that concerned about us. whereas the ""natural"" ""clean"" product grifters are ALWAYS talking about people with unusually sensitive skin. like... no wonder so many people with sensitivities and allergies end up turning to ""clean"" stuff. frustrating as hell.
