Type of acne Acne vulgaris is a broad term for the most common of the three main types of acne. Acne vulgaris encompasses different types of acne lesions (also known as pimples). Acne vulgaris forms when hair follicles become clogged with excess sebum, bacteria, and dead skin cells. This results in a comedo, also known as a clogged pore. Acne vulgaris can be commonly found on the face, back, and chest, as these areas of the body tend to be saturated with pilosebaceous units. As skin regenerates, old cells slough off, and if these dead skin cells aren’t flushed from the pores and manage to combine with sweat and oil, they could be trapped and result in the formation of a pimple. Blackheads, whiteheads, papules, pustules, nodules, and cysts are the most common types of pimples . Blackheads: Blackheads, also known as open comedones, generally form on the face, neck, chest, and back. They’re categorized by their black appearance where the pimple comes to a head. The black marking isn’t from dirt or infection but happens when the sebum oxidizes at the surface. Blackheads are generally caused when pores are clogged due to debris and oil buildup. Whiteheads: Whiteheads are clogged follicles covered by a thin layer of skin that appear as white bumps or spots. Papules: Papules are inflamed lesions that may appear red, and can be sensitive and painful. Pustules: Pustules are another type of pimple that's’ an inflamed lesion. They are generally pus-filled and may appear white or yellow. Though it may be tempting to extract their pus, popping pustules can lead to acne scarring. Want to learn more?

These acne lesions are generally between 1 and 2 centimeters wide . Cysts: Cysts are a severe form of acne lesion that are inflamed and filled with pus. They are generally painful and may require professional medical treatment. Beyond acne vulgaris, there are different kinds of acne conditions, including acne fulminans and acne mechanica . Acne fulminans: This is a rare but very severe form of acne that comes on abruptly in adolescent males, characterized by inflammatory nodular acne on both the chest and back. It can result in severe scarring and painful joints, along with other health issues such as fever and joint pain. Acne mechanica: This form of acne is triggered by excess pressure, heat, and friction on the skin, and is often found among athletes and those already prone to acne breakouts. It’s characterized by small bumps that can range from tiny comedones to inflamed lesions. Types of acne lesions Typically, a patient with acne presents with the following lesions: Non-inflammatory lesions • Open comedones (blackheads). • Closed comedones (whiteheads). Inflammatory lesions • Papules – small, pink or red inflamed lesions that can be tender to touch. • Pustules – inflamed papules with white or yellow pus-filled tops.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
