2,000-year-old roman face cream with visible, ancient fingermarks
The contents were so well preserved (you can still see finger marks in the cream) that the team was able to recreate the product from fresh ingredients. The main constituent of the cream was animal fat mixed with starch and tin oxide. “the Londinium cream” was primarily made up of animal fat, probably from cattle or sheep. They also detected starch, which was likely isolated by boiling roots and grains in water. In addition, the cream contained a tin dioxide mineral called cassiterite with the chemical formula SnO2.
