Acne vulgaris is the formation of comedones, papules, pustules, nodules, and/or cysts because of pilosebaceous unit obstruction and inflammation (hair follicles and their accompanying sebaceous gland). Acne appears on the face and upper chest. Adolescents are the most affected.
Diagnosis is accomplished through examination. Depending on the severity, treatment may include a variety of topical and systemic agents aimed at reducing sebum production, comedone formation, inflammation, and bacterial counts while also normalising keratinization.
Alopecia areata is a condition in which the immune system attacks hair follicles, resulting in hair loss. Hair follicles are skin structures that produce hair. While hair loss can occur anywhere on the body, alopecia areata most commonly affects the head and face. Hair typically falls out in small, round patches about the size of a quarter, but hair loss can be more extensive in some cases.
Alopecia areata progresses differently in everyone. Some people have hair loss episodes throughout their lives, while others only have one. Recovery is also unpredictable, with some people experiencing complete hair regrowth while others do not.
Acanthosis Nigricans is a skin condition that causes dark, thick velvety skin to develop in body folds and creases. It most commonly affects the armpits, groyne, and neck.
Obese people are more likely to develop Acanthosis nigricans (ak-an-THOE-sis NIE-grih-kuns). In rare cases, the skin condition may indicate cancer in an internal organ, such as the stomach or liver.
Treating the underlying cause of acanthosis nigricans may restore the skin's normal colour and texture.
Acanthosis Nigricans is distinguished by dark, thick, velvety skin in body folds and creases. It is most found in the armpits, groyne, and back of the neck. It takes time to develop. The affected skin may be itchy, odorous, and develop skin tags.
