Background

CD59 glycoprotein, also known as MAC-inhibitory protein (MAC-IP), membrane inhibitor of reactive lysis (MIRL), or protectin, is a protein that in humans is encoded by the CD59 gene. CD59 attaches to host cells via a glycophosphatidylinositol (GPI) anchor. When complement activation leads to deposition of C5b678 on host cells, CD59 can prevent C9 from polymerizing and forming the complement membrane attack complex. It may also signal the cell to perform active measures such as endocytosis of the CD59-C9 complex. Viruses such as HIV, human cytomegalovirus and vaccinia incorporate host cell CD59 into their own viral envelope to prevent lysis by complement.

I love SPF 15
I love the SPF 15, but it is so hard to find in stores. I love that I could get it on Amazon!

Only SPF 15. Best For Overcast Days or Less Exposure.
I love Coppertone Sport sunscreens because they stay on longer than many and don't drip painful lotion into my eyes when I sweat. This spray-on version is only SPF 15, so, as a fair person, I can use it in direct sun only for 30-60 minutes of exposure or if I'm outside during an overcast day when, yes, I can still burn. SPF blocks 93% of the sun's rays, which sounds like a lot until you consider that SPF 50 blocks 98% of the rays. Sprays like this are especially useful if I'm by myself and need to reach difficult places such as my back. For the rest of me, I spray my skin, then rub in for complete coverage. For my face and neck, I spray into my hands, then apply to those areas. You don't want to spray directly on your face when you can inhale it or get it in your eyes. If you don't have sun-sensitive skin or don't expect to be in direct sunlight for long, then this is a great option for easy application. Just make sure you apply enough of it and reapply throughout the day. -- Debbie Lee Wesselmann

Summer Essential at great price
Great deal ahead of the summer sun. Product was the perfect match for my golf trip. Felt like it held up even in the heat and sweaty environment.
