The smell of summer
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
Love this lotion and its smell! Offers both protection and hydration and is my go to sunscreen for tanning / laying around. It'd definitely not my sunscreen for running / workouts / etc. because it doesn't feel like it hold up great to sweat.

Highly recommend for face sunscreen care!
Style: SPF 30, Size: 1 Fl Oz (Pack of 1)
A great choice for waterside sun protection. Rolls on smoothly and protects your skin from sun. As someone with sensitive facial skin I was relieved to find no issues after applying for a week straight. I plan to keep this product regularly on hand.

Expensive but good
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
It's not the best for your skin but it works and doesn't leave white cast and is nice and easy to apply to the skin. It smells good too but youll run out quick and have to buy more. Lasts like a month or something if you are apply to face, neck, arms, legs.

One of my favorite Sunscreens
Style: SPF 30, Size: 3 Fl Oz (Pack of 1)
This sunscreen is great. When applying, I am very pleased at how easy it is to spread and soak into my skin. It also stays on during the day and also whenever I get in the water. I love the smell as well.
