Great for Sun Allergy Rashes!
Scent: Unscented, Scent: Unscented
I have an autoimmune disease called Sjogren’s Disease. With that, for me, comes a sensitivity to the sun in the form of sun allergy rashes. Also with that, I did a deep dive on the best sunscreens and read a lot of reviews on here. I put some of the outer sides of elbows where my sun allergy rashes were when I received it. There was slight sting, but the skin there was already slightly broken. I really love the texture of it, how it feels on my skin and that there's no white cast. It’s moisturizing, too, with no greasiness. Absorbed really well.

The best mineral sunscreen
Scent: Unscented
I’m so impressed by this sunscreen! I’ve been using mineral sunscreens for years and this blows every other one I’ve tried out of the water. It is silky smooth and applies so easily, absorbs well and doesn’t feel greasy or heavy. It doesn’t leave a white cast but it still protects very well! Of course like any sunscreen it’s only as effective as your usage, so reapplying is paramount. The unscented truly has no smell to it, which is something I appreciate. Using it for the first time, neither myself or my fair kiddos got sunburnt. It’s just all around a fantastic, clean mineral sunscreen and will be my go to from now on!
