Great product. Sun protection and hydration
I just discovered this brand a year or two ago and have not been disappointed in their products. This item specifically I can feel my face a lot softer all throughout the day. I bought it for sunscreen so that was just an added bonus. I’ve finished one bottle now and started my second one. I recommend

Beautiful finish, but not for sensitive eyes
It has a very beautiful dewy finish on the face. I wish I could keep using it however it is not good for very sensitive eyes, causes extreme itching and watering to the point where I cannot open my eyes.

Just what we needed
I am in love with this sunscreen. My daughter has very oily skin and she has tried many other susnscreens. All of them cause her skin to break out except this one. She loves putting g it on and even says it’s “kind of satisfying to put on because it disappears instantly”. It’s been working great and she hasn’t been getting sunburnt. I would definitely buy it again!!

Great sun protection for high elevation!
Excellent skin care product for those of us that spend lots of time outdoors in the mountains! My dermatologist recommended this product, and it definitely has been protecting my face while cycling, hiking, kayaking, and just hanging out in the sun!
