Which of the following skin lesions typically appear as raised, itchy welts?

Wheals are raised, itchy welts that often result from an allergic reaction or other forms of skin irritation. They are characterized by their ability to vary in size and shape, and they commonly have a pale center surrounded by a red flare. Wheals are also transient, meaning they can appear suddenly and may fade away without leaving a trace.

Understanding wheals is important in esthetics practice because they can indicate underlying sensitivities or allergic responses, which may affect the choice of treatments and products used on a client's skin. Recognizing the typical characteristics of wheals helps estheticians respond appropriately, ensuring client safety and satisfaction.

In contrast, ulcers are more serious skin lesions that involve the loss of the epidermis and possibly the dermis or deeper layers, leading to a potential risk for infection and scarring. Milia are small, white cysts that appear on the skin, commonly found around the eyes and cheeks, and are not raised or itchy. Pustules are raised lesions filled with pus, often associated with acne, rather than being primarily itchy welts. Thus, understanding the unique nature of wheals helps distinguish them from other lesions that do not share the same characteristics.
