Causes of Cystic Acne
- The true cause of cystic acne is often unknown. Androgens (hormones) tend to trigger in those predisposed.
- Plugging
of hair follicles by a protein known as keratin causes the formation of
so-called whiteheads and blackheads, which form when the plugged
sebaceous glands within the hair follicles continue to secret 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 (e.g., zits or Pimples). The zits may
then enlarge and form cysts.
- Irritation
by inflammatory fatty acids within the plugged follicles, and an
overgrowth of the bacteria Proprionibacterium together contribute to
the process of acne formation.
- Irritating creams and oils
- Corticosteroid medication taken orally
Adolescence,
male sex, certain drugs (e.g., Dilantin, Lithium, birth control pills,
steroids), humid/hot weather, supplements (e.g., DHEA), and constant
skin friction (e.g., use of motorcycle helmets, telephones) are some of
the common risk factors.
