How acne develops
Acne occurs due to a combination of factors including genetics and hormones. Sebaceous glands are glands attached to hair follicles in the skin and produce an oily substance called sebum.
There are 4 basic steps in the development of spots:
- 1
Hair follicles become blocked with skin cells and sebum
- 2
Sebaceous glands enlarge and sebum production increases
- 3
Overgrowth of a bacteria called Cutibacterium acnes due to increase in sebum
- 4
This leads to inflammation, rupture of the follicle and formation of spots
