I have been using BullFrog for years. My mom used it on me when I was younger and I still use it. I love the BullFrog SuperBlock Lotion SPF 45 because of the higher SPF. I have very fair skin and need a high SPF to be protected from sunburns. I also like to use a higher SPF on my children. I love that I can apply this on them and feel they are safe from sun damage. I love that it's sweat and water proof and lasts longer than most sunblocks. Also after using this sunblock lotion it doesn't leave mine or my children's skin feeling greasy or sticky. This is a huge bonus, I have used some sunblocks in the past that have left my skin feeling sticky and it was horrible, BullFrog doesn't do this. Scent I don't really notice much of a scent. Absorption Absorbs into mine and my children's skin well. Does not leave our skin feeling oily. Longevity Lasts as long as I would expect from a sunblock. Effectiveness Very effective at keeping mine and my children's skin safe from sunburns and sun damage. Ease of Application Fairly easy to use bottle.
