What condition is commonly known as cold sores?

Cold sores are commonly known as herpes simplex, specifically caused by the herpes simplex virus (HSV). This viral infection typically manifests as painful blisters or sores on or around the lips and mouth. The condition often recurs in individuals who are infected, particularly during times of stress, illness, or sun exposure.

Understanding this condition is important for those in cosmetology because cold sores are highly contagious, especially when active. It’s crucial for cosmetologists to recognize the signs and symptoms in order to avoid providing services that could exacerbate the condition or risk transmission to clients.

The other conditions listed, such as psoriasis, contact dermatitis, and impetigo, are unrelated to the herpes simplex virus. Psoriasis is a chronic autoimmune skin condition characterized by red patches covered with thick, silvery scales. Contact dermatitis is an inflammatory skin reaction caused by exposure to allergens or irritants. Impetigo, on the other hand, is a bacterial skin infection that leads to red sores, primarily in children.Therefore, the association of cold sores specifically with herpes simplex makes this answer the most accurate in the context of the question.
