Beauty Fact: The other day I heard that fish scales were in lipstick. What?! I had never heard this before so I researched it and it's true! "Guanine" is the ingredient in cosmetics (not just lipstick) that is made from fish scales and related to guano, bird poo. It's technically a colorant but it's good at covering up blemishes and makes products more opaque. How interesting! Does this make anyone grossed out? Leave a comment and let me know!
