The symptoms we usually call acne are a skin disease called acne vulgaris.
Acne - the red bumps that frequently appear on the face, chest, and back - is a condition in which hair follicles (sac-like parts of the skin at the roots of hairs) and sebaceous glands are inflamed.
The main causes of acne include:
- 1Excess sebum production
- 2Hyperkeratinization (a disorder of the cells) of the exit of pores resulting in clogging
- 3Proliferation of propionibacterium acnes (P. acnes) bacteria
