Acne,

 Acne, also known as common acne, is a skin condition that affects almost everyone at some point in their lives. It occurs when the skin's oil glands produce excessive sebum, leading to the blockage of hair follicles. If the follicle remains open, it forms a blackhead, and if it is closed, it forms a whitehead. These plugged pores can develop into inflamed pimples, lumps, or nodules. While acne is commonly associated with adolescence, it can also occur in adults, with about 20% of cases happening in adulthood. The condition typically starts during puberty and improves in the early 20s. Acne can affect both males and females, with teenage boys experiencing more severe cases. Women are more likely to have mild to moderate forms of acne into their 30s and beyond. Acne primarily appears on the face but can also occur on the neck, chest, back, shoulders, and upper arms. Contrary to popular belief, acne is not caused by diet, hygiene, or sexual activity. Heredity and hormones play a significant role in its development, and no amount of diet or excessive cleansing can alter one's predisposition to acne
