I tried Banana Boat sunscreens in the SPF 15 and the SPF 30. The 15 is nowhere near enough protection for anything and the 30 still left me with blisters and redness. The SPF 50 is probably where the best protection starts for me. If I can find higher I will but this does a great job for me as long as I remember to reapply. My boyfriend picked this up for us on our way to a local Princeton Rays baseball game. We grabbed a bottle up at drugstore and he picked it out because I told him to be sure to get something 50 or above. We argue constantly on the effectiveness of higher SPF sunscreen but I think he's coming around to see that 50 is better than 30. The sunscreen comes out white like many others do. It goes on smooth and it's very cool to the touch. It's actually kind of cold on contact, even after the bottle has been out in the sun for a while. This bottle also has one of my favorite designs. I like the upside down bottle because I can get more product out of it. I also like that it's #2 plastic which I can recycle. Anyway, that aside, this provides the perfect amount of SPF protection for outdoor events without me or my guy having to constantly reapply. The baseball games usually last anywhere from 2-4 hours depending on how the games go. I can apply block to both of our faces and arms for added protection and at the end of the game. I rarely ever have any burns. I do get some sun though. The high SPF protects me from blistering and redness but it still allows enough sun rays through to allow me to tan somewhat. I have to be careful getting this around my eyes. My lids need protection just like everywhere else but it's hard to apply the thick lotion around the eyes and mouth without getting it in them. I usually put the product in my hands, rub it out, and then apply to my face just to be safe. This sunblock lasts through sweat and hours of baseball games. I have to say that the SPF 50 really does the trick. Scent It actually doesn't have much of a scent. Absorption I have to work it into my skin because it's a lotion but it's worth it. Longevity If I'm outdoors or at a sporting event, one application lasts all day. Effectiveness It protects me arms, shoulders, and face perfectly without any damaging blisters or burns. Ease of Application I wish it had a spray nozzle or aerosol but it's easy to apply. I do have to get help with my back though.
