Acne is a common skin condition that affects millions of people worldwide, particularly teenagers and young adults. It occurs when hair follicles become clogged with oil and dead skin cells, resulting in the formation of pimples, blackheads, and whiteheads. Acne can occur on the face, neck, chest, back, and shoulders, and can range from mild to severe. Factors that can contribute to acne include hormonal changes, genetics, certain medications, and lifestyle factors such as diet and stress. While acne is not a serious health condition, it can have a significant impact on self-esteem and quality of life, especially in severe cases.
