What is Why do I have acne? and explain in detail?
Acne is most commonly linked to the changes in hormone levels during puberty, but can start at any age. Certain hormones cause the grease-producing glands next to hair follicles in the skin to produce larger amounts of oil (abnormal sebum). This abnormal sebum changes the activity of a usually harmless skin bacterium called P. acnes, which becomes more aggressive and causes inflammation and pus. The hormones also thicken the inner lining of the hair follicle, causing blockage of the pores (opening of the hair follicles). Cleaning the skin doesnt help to remove this blockage. Acne is known to run in families. If both your mother and father had acne, its likely that youll also have acne. Hormonal changes, such as those that occur during the menstrual cycle or pregnancy, can also lead to episodes of acne in women. Theres no evidence that diet, poor hygiene or sexual activity play a role in acne.
