Canada has taken a stance over anything marked over SPF 50, and there is national draft guidance on what chemicals to avoid due to low testing or egregious claims in protection where in truth their claim is unsubstantiated.
I've been experimenting for years. Well enough to know that a cream is not going to be enough protection. I won't be able to rely on something from a bottle to keep me safe. My lotion screen will amount to about 15% of my broad spectrum needs.
The rest has to be barrier protection; like clothing / hats / glasses.
The desert will be an experiment that I can't risk
- so I HAVE to go with cloth barriers as a primary uv blocker over creams. (of course I'll still bring my arsenal - lol over 50% of my first aid kit IS sun related, aftercare, preventative, emergency water patches, second skin, blister gel, aloe vera gel)
My favorites are
Face - Aveno's Baby sunscreen is the only one that doesn't burn my eyes. So I like that one alot. It comes in Broad Spec 35+
Body - Kiss my Face - 40SPF Broad Spectrum, because of it's easy to read ingredients (and got the clearing of the toxic 10 from Health Canada)
It's really hard to find a good one that works for your skintype. I find I don't break out from the chemical screens, but I don't like them either.
Banana Boat makes a "natural - lol" one - it's not terribad and super easy to find.
I prefer mineral screens and even then Zinc over Titanium. It's a constant battle to find the "right one" for the "right situation". The all natural ones work fine for Canadian exposure - where we have an abundance of tree, cloud, shade cover. Plus in the rainforest we're rarely exposed skin wise - always raining
It sucks because experimenting with brands is a high cost adventure - shit ain't cheap. So I go with what I know works and if the situation for a week - DEMANDS a chemical screen - then I'll have to suck it up and go with it.
