What are vesicles?

Vesicles are defined as small blisters that are filled with fluid. These raised lesions typically occur in clusters and can vary in size, often forming as a result of conditions such as allergies, infections, or skin irritations. Vesicles are usually characterized by their clear fluid content and thin walls, distinguishing them from other skin lesions.

In contrast, deep open sores pertain to more severe skin damage, while large areas of flaking skin usually describe conditions like psoriasis or eczema, which involve dry or peeling patches rather than fluid-filled blisters. Additionally, dark spots caused by increased melanin are more accurately referred to as hyperpigmentation, which is a different phenomenon altogether and does not relate to vesicular formations. Understanding these differences highlights the unique characteristics of vesicles as a specific type of skin lesion.
