Great Product
Color: White, Size: 0.15 Ounce (Pack of 1)
This lip balm was recommended by my surgeon to protect my lip from uv rays. Surprisingly, it does not have that yucky spf taste other lip balms have. It does create a white cast, but I find if I lightly put it on the cast is not prominent, and I am Caribbean with deep tan skin. Very grateful this lip balm does its job!

Protect Your Lips
Color: White, Size: 0.15 Ounce (Pack of 1)
This chapstick feels great on my lips, nice smooth texture, no unpleasant taste. It definitely protects my lips from the sun. The only downside is that it has a white tint to it on my lips; I wish it were completely sheer.

A good sun solution for sensitive lips!
Color: White, Size: 0.15 Ounce (Pack of 1)
Having sensitive lips can be super frustrating. They burn SO easily in the sun. But most sunscreen lip balms on the market irritate them. Those that don't irritate aren't moisturizing at all, so my lips become dry and chapped. Which leads to more sensitivity. Ugh. But so far this Sun Bum SPF 30 has worked for me! No sunburnt lips. No irritation. Enough moisture to keep my lips soft and healthy while working or playing outside. Sure, it's s not really pleasant tasting when it gets in your mouth, and like most zinc-based sunscreens, it makes my lips milky white. But it works for my picky lips and it's a good value for the money--it's become my summertime staple.

Hydrates, leaves a slight white film, not travel friendly
Color: White, Size: 0.15 Ounce (Pack of 1)
I wear lip balm regularly. As a matter of fact, I always have some with me. Tubes are placed in various areas around my house, I have one in my car, in my backpack and a couple tubes at work. I'm seriously never without it so I kind of consider myself a lip balm expert. The only thing most of the ones I use don't have is SPF. Since I live in an area that is fairly sunny year round, you think I'd be better about that. Well, I'm looking to change that. I saw this Sun Bum SPF 30 Mineral Sunscreen Lip Balm and read some of the reviews. They seemed overwhelmingly positive. I'm familiar with the brand and since it was covered under my HRA, decided to try this one out along with a few others. It glides on easily and moisturizes well, but it left a slight white film on my lips. Not my favorite but it did fade. It's unscented and doesn't have any flavor, which is good. I loathe lip balms with any type of taste to them. Good or bad. It has clean ingredients and offers great sun protection but it doesn't withstand heat itself. If you like to carry one in your pocket, backpack or keep in your car, it will melt. I do like this lip balm but it has some negatives, as stated above. It made my lips feel soft and hydrated but it's not travel friendly. I wouldn't discourage buying it, but if you want a balm to carry around with you, I'd be hesitant to recommend it.
