Understanding Acne
Types, Causes, and Symptoms
Acne is a common skin condition that affects millions of people worldwide. It occurs when hair follicles become clogged with oil and dead skin cells, leading to whiteheads, blackheads, or pimples. There are several types of acne, including comedonal acne (whiteheads and blackheads), inflammatory acne (papules, pustules, nodules, and cysts), and hormonal acne, which often appears around the jawline and chin in adults.
The causes of acne are multifactorial and can include hormonal changes, excess oil production, bacteria, and genetics. Hormonal fluctuations, particularly during puberty, menstruation, or pregnancy, can trigger acne by increasing oil production. Certain medications and diet can also play a role, though the exact impact of diet is still debated.
Symptoms of acne can range from mild to severe, affecting not only the face but also the back, chest, and shoulders. Common signs include the presence of whiteheads, blackheads, pimples, and sometimes painful cysts or nodules. Understanding the type and severity of acne is crucial for determining the most effective treatment approach.
