A blister is a small pocket of fluid 💦 that forms in the upper layers of the skin, typically caused by friction, burning, or infection. Think of it as your body's way of protecting damaged skin. The fluid cushions the underlying tissue, allowing it to heal. It's like a natural bandage. Blisters can be painful, but they usually heal on their own if left undisturbed. Popping a blister can increase the risk of infection. So, it's best to let them run their course!
