- The skin pore opens into a follicle.
- The follicle is made up of hair and sebaceous gland .Sebaceous gland secrets sebum(oil),sebum lubricates the skin.
- Acne occurs when the hair follicle of the skin gets clogged with oil, dead skin or bacteria.
The main causes of acne are as follows:
- Overproduction of oil (sebum).
- Improper shedding of dead skin cells resulting in irritation of the hair follicles of your skin.
- Development of bacteria in the pore.
- When the body produces an excess amount of sebum, and dead skin cells, together in the hair follicles results in the formation of a soft plug,( creating an environment where bacteria can develop)
- Soft plug developedin the skin causes the follicle wall to bulge and produces a whitehead, or it may darken, causing a blackhead.
- Pimples are raised red spots with a white center which are developed when blocked hair follicles gets inflamed or infected. Blockages and inflammation that develop deep inside hair follicles produce lumps beneath the surface of your skin called cysts.
