Acne is a common skin condition that occurs when hair follicles become clogged with oil, dead skin cells, and bacteria. It typically appears as pimples, blackheads, whiteheads, or cysts, and most commonly affects areas of the skin with a high number of oil glands, such as the face, chest, back, and shoulders.

The exact cause of acne is not fully understood, but it is believed to involve a combination of factors including excessive oil production, abnormal skin cell shedding, bacteria on the skin, and hormonal changes. Acne is most commonly associated with the hormonal changes that occur during adolescence, but it can also affect people of all ages.

Treatment options for acne may vary depending on the severity of the condition, but typically include topical medications (e.g., creams, gels, or lotions containing ingredients like benzoyl peroxide or retinoids), oral medications (such as antibiotics or hormonal contraceptives), or in some cases, procedures like chemical peels or laser therapy. It's important to note that treatment effectiveness can vary from person to person, and it may take time to find the most suitable approach for managing acne.
