Light, non-greasy sunscreen that actually feels good on the skin
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
This sunscreen has become one of my favorites for days outdoors. It goes on smoothly, absorbs quickly, and doesn’t leave that heavy, sticky feeling some sunscreens do. The scent is light and tropical, just enough to smell like summer without being overpowering. It gives great coverage and protection without needing constant reapplication.
I like using it for beach days, walks, or even outdoor workouts since it holds up well when sweating. It feels moisturizing on the skin and hasn’t caused any irritation.
Tip: apply it a few minutes before heading outside so it has time to absorb and start protecting your skin.

Smells Amazing and Works Fabulous!
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
I love the smell of Hawaiian Tropic sunblock. Not only does it smell delicious, it lasts better than any others I have used. I put it on and wait for at least 15 minutes before going into the sun so it can set in. When I am outside I reapply about once an hour. If I am in the water I tend to reapply at least every 45 minutes. This product does its job without being greasy or heavy.

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.
