Explanation;
A papule is an area of abnormal skin tissue that is less than 1 centimeter around. A papule has distinct borders, and it can appear in a variety of shapes. Papules are often called skin lesions, which are essentially changes in the color or texture of your skin.
-Papules and pustules are the result of an increase in oil and bacteria trapped inside the pore by dead skin cells. Papules occur when the clogging causes a hair follicle to become inflamed. When this happens, the body's immune system sends white blood cells to fight the infection.
