        Good to use, but won't buy again
        Scent: Coconut, Size: 0.15 Ounce (Pack of 1)
        I didn't like the coconut taste and it made my lips a bit more dry. looks good when you put it on and great spf coverage though, but won't buy again.

        My new-found favorite!
        Scent: Pineapple, Size: 0.15 Ounce (Pack of 1)
        I wear lip balm daily and reapply multiple times in a day. This is one of the first times trying this brand, but this is now one of my favorite lip balms! I love the “flavor” of the pineapple as it’s not super synthetic or chemical tasting. And the texture of the balm when I put it on my lips is exceptional! It’s not sticky and glides on really nicely. It’s got a more silky texture than most lip balms but doesn’t give a glossy look like you’d expect like products that give the same feeling. This will definitely be my go-to moving forward.

        Reliable Spray for Hard-to-Reach Spots and Reapplication
        Size: 5.5 Ounce (Pack of 1)
        I picked up this spray specifically to cover the spots I can’t reach with lotion (my back), and it’s been super handy. The spray applies evenly, and while it has a familiar sunscreen scent, it fades quickly. I’ve worked it into my routine for touch-ups, especially on homeward-bound afternoon bike commutes. I keep the can in my bike bag and give everything a quick respray before heading home. It holds up well during activity and gives me solid protection for about two hours, after which I reapply. One thing to note: it does leave a bit of a shiny finish, which is fine for arms and legs, but I skip it on my face during the day because I don’t love the reflective look. That said, if it’s late or I’m not worried about how shiny my face is, it does the job. The SPF 100 is a plus for extended sun exposure, and I like knowing that I’ve got extra coverage when I need it.
