What condition is characterized by the appearance of small, painful blisters at the affected site?

Herpes simplex is characterized by small, painful blisters that typically appear on or around the lips and mouth, though they can also occur in other areas of the body. This condition is caused by the herpes simplex virus (HSV), which can lead to recurrent outbreaks. The blisters often present in clusters and are fluid-filled, providing a distinct and recognizable symptomatology.

The nature of these infections can result in discomfort due to inflammation and can also lead to additional symptoms such as tingling or itching before the blisters appear. The presence of these characteristics distinguishes herpes simplex from other conditions listed.

In contrast, impetigo usually presents as red sores that can ooze and form a honey-colored crust, conjunctivitis is an inflammation of the conjunctiva causing redness and discomfort in the eyes, and eczema typically manifests as dry, itchy patches of skin rather than blisters. Understanding these distinctions is essential for proper identification and treatment in beauty therapy contexts.
