Yes, you can use flour and water to make a simple dough that mimics the texture of skin or scar tissue. Mix 1 cup (130 g) of flour with 1 cup (237 mL) of water with a pinch of salt and a tablespoon (15 ml) of oil. Stir these ingredients over heat until you achieve a doughy consistency. You can put this “skin” wherever you like on your body, and wet it slightly to make it smooth. Add makeup to create a realistic skintone. If you want to make a cut, carefully make a slit in the dough and pour on a little fake blood!
