Nefertiti's secret
Q: So what could Nefertiti have used to make her skin so flawless?
A: I suspect she used Vitasure Day Cream since it would have given her the ultimate protection from the harsh sunlight of Egypt - SPF 30. The hydration from the Day Cream must obviously have given the smoothness that is so evident. It is quite possible that she used Vitasure Gentle Cleanser to wash although I've heard that ass's milk was popular at the time for facial cleansing. Of course, we cannot confirm all this unless the papyrus scrolls relating her personal life are found.
