A

12 to 15

41
Q

acne vulgaris develops where

A

sebaceous follicles

primarily on face and upper chest and back

42
Q

acne vulgaris therapy targets what four factors responsible for lesion formation

A
  • increased sebum production
  • hyperkeratinization

43
Q

physiological factors of acne vulgaris

A
- Follicular
hyperkeratinization
- Excessive sebum
production
- Follicular proliferation
of Propionibacterium
acnes
- Inflammation secondary
to the action of
inflammatory products
produced by P. acnes
- Excessive production of
sebum is related to
androgenic hormones
