Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically appears as areas of redness and small, raised bumps, often called pimples or zits. While acne most commonly appears on the face, it can also occur on the neck, chest, back, and shoulders.
Acne can take many forms, ranging from mild to severe, and may last for weeks, months, or even years. It can cause emotional distress, low self-esteem, and scarring.
Several different factors can contribute to the development of acne. Hormones, especially during puberty, can cause an increase in oil production in the skin. Certain medications, cosmetics, and stress can also exacerbate acne. Genetics can also play a role in the development of acne, and it may be more severe in some individuals due to their skin type or medical conditions.
