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.

No white residue
Size: 3.4 Fl Oz (Pack of 1)
I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.
