A Dutch researcher by the name of Jalila Essaidi has created a composite of human skin that can literally stop bullets.
Made by combining spider silk protein with goat milk and implementing the mix in human skin, the result is so strong it can stop a (partially slowed) bullet fired by a .22 calibre Long Rifle.
This sounds great in theory, but I’m not sure about the usefulness of this in a real world situation. Even if it could stop any bullet, the impact would still be powerful enough to break bones and turn internal organs into jam. It would be similar to being hit with a baseball bat by an angry silverback gorilla. The bat wouldn’t pierce the skin, but severe internal bleeding and possibly death would likely occur.
So I don’t see the purpose of bulletproof skin unless the one wearing it is a 600 pound person with enough fat to absorb any impact. But in that case, getting shot would be the least of their worries.
