Sunscreen - Never miss a spot | |||||||||||||||||
Right now, the only way to find the spots you missed applying sunscreen to is to spend a couple hours in the sun. A painful and damaging method. How about an addative in sunscreen that shows up under a black light or another other controlable light source (flourscent perhaps?). After applying sunscreen, walk under the light and you can check to see where the missed spots are.

An optical brightner such as tinopal could be added so it shows up under black light. Of course, it would have to be FDA tested.
They do make a variety of lotions that go on purple, and then fade to clear. The chemical is found in magic trick invisible inks- exposure to oxygen causes the dye to fade.
