Oregon Esthetician State Board Practice Exam - Prep Guide & Practice Questions

A macule is a type of skin change that is characterized as being flat and distinctly different in color from the surrounding skin. This color difference can be brown, red, white, or other shades, and it does not elevate above the surface of the skin. Common examples of macules include freckles and certain types of rashes, which are not raised and do not produce any texture change in the skin.

In contrast, other options like vesicles, bullae, and pustules involve elevated skin changes. Vesicles are small fluid-filled sacs, bullae are larger blisters, and pustules are raised lesions that contain pus. These types of lesions are all elevated, contrasting sharply with the flat nature of a macule. Understanding these definitions aids in recognizing various skin conditions and their characteristics, which is essential for effective assessment and treatment in esthetics.
