Wonderful hot weather spritz
Size: 1.7 Fl Oz (Pack of 1)
I used this on a recent cruise to the Mediterranean. A lovely spritz on a hot day really was so refreshing! I highly recommend it! And it smells so good!

Amazing Product
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen mist feels like water. It’s truly refreshing when applied. I have ultra sensitive skin and eyes and I’ve experienced no irritation from this product.

Refreshing!
Love, love, love this! It feels so refreshing when I spray it on my face. The scent is sweet but not overpowering, and it’s not oily at all. I usually apply it after my moisturizer and throughout the day whenever I need a little pick-me-up.

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.
