A vesicant is very similar to a vesicatory; it's an agent that causes blistering. Think of it as a chemical warfare agent or a potent skin irritant. Vesicants cause severe burns and tissue damage, not just a minor rash. They're nasty stuff you definitely want to avoid. 🤕 It's the *cause* of blistering, whereas a blister is the *effect*. Vesicants are substances that damage skin cells, leading to blister formation. Yikes! 😬
