Yeah so everyone knows that the sun is not really our friend and unprotected exposure can lead to skin cancer. The makers of this little gadget know this too, but they want to make sure that people put on exactly the right amount of SPF they need. Though still a concept device, the mytan intelligent sunscreen dispenser promises to figure out exactly what SPF you need to be safe when you input your proper info: skin color,freckle amount,eye color, etc.
