Males have a more severe form of acne, and a later onset than females.
The true cause is often unknown. Androgens (hormones) tend to trigger in some cases.
Plugging of hair follicles by a protein known as keratin causes the formation of so-called whiteheads and blackheads. The plugged sebaceous glands within the hair follicles continue to secrete sebum (an oily secretion). Sebum and skin cells cannot exit, thus accumulating in mass, causing the follicle to swell. If the swelling continues, it may rupture, allowing the surface bacteria (normally found on the skin) to enter and cause local infections (Pimples), then enlarge and form cysts.
Irritating creams and oils
