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.
