Easy to use and it actually works
So I live in Florida, taking care of your skin is super important. This is actually a great product, I actually use it to set my make up on the rare occasions that I wear any but on days that I don't This product is still great. It's not heavy or leaves a white cast like some of the other sun protection does. It doesn't leave my skin greasy but it helps to feel moisturized. Honestly I just spray it as I'm about to leave the house and I'm good to go. Plus it actually smells good, like very light tropical beach vibe. Best part it's never caused me to break out on my skin because I have very sensitive skin.

Ulta Recommendation That Actually Delivered
Size: 1.7 Fl Oz (Pack of 1)
I was originally recommended this product by a representative at Ulta—and it completely changed the game! It’s super easy to apply, smells great in my opinion, and gives me a refreshing, lightweight feel without the heaviness of typical facial sunscreens.

Great scent and feel
Size: 1.7 Fl Oz (Pack of 1)
Not sure I understand the blue light feature of this, but I love how this feels during a hot day! I usually carry this when I go to the pool with the kids and use it to reapply after getting out of the water and watching them from the pool deck. I burn fairly easily and haven't burned using this, leading me to believe that it functions well. I like the smell and I like the cooling mist on hot summer days! One quibble, it does leak if not tightened carefully!

Best mineral sunscreen
Size: 3.4 Fl Oz (Pack of 1)
Best sunblock. No white cast if you use the 30 spf. My dermatologist recommended this years ago and I’ve used it since.
