Blisters

A blister is a small pocket of fluid that forms between the layers of skin, usually as a protective response to injury or irritation. It often appears as a raised, fluid-filled bump and can result from friction, burns, allergic reactions, or skin infections. The fluid inside helps protect the underlying skin, allowing it to heal. While most blisters are harmless and resolve on their own, keeping them intact prevents infection. If a blister is large, painful, or pops on its own, it may require gentle care or medical attention to prevent complications.
