Pimples are the lesions on the skin caused by sebaceous gland disorder (the blockage of skin pores), which mostly occurs on the face.
It may also develop on the chest, neck, back and upper arms. ‘Acne lesions’ is the term commonly referred to pimples.
It mostly occurs in adolescents (young people) and sometimes in children and adults.
Before understanding the cause of pimples, it is necessary to know what makes the skin to develop pimples.
The skin is covered with millions of tiny pores, which are connected to sebaceous glands (oil glands). Again, each gland is connected to follicle, a tiny canal that holds a hair.
The sebaceous glands produce an oily substance, called sebum, to keep the skin moist, shiny and healthy. This oil flows to the skin’s tiny pores through the follicles.
Once these sebaceous glands are obstructed by dirt or other factors, the sebum blocks the pores resulting in pimple outbreaks.
A number of factors contribute to the cause of pimples. The most common cause of pimple is hormonal imbalance. The change in the hormone levels makes the body to produce more sebum, making the skin greasy. The excess sebum blocks the pores and results in pimples.
The elevation of androgens (hormone) over-stimulates the sebaceous glands in the skin to produce more sebum. The excess sebum then plugs the pores and leads to the growth of the pimples.
Another common cause of pimples is bacteria. Bacteria that usually reside on the skin produce enzymes, which in turn make the body to produce excess sebum from oil glands, thus play a role in the cause of pimples.
Propionibacterium acne, Pityrosporon ovale, Staphylococcus albus and Corynebacterium acne are the most common bacteria that cause pimples on the skin. Infections such as dental sepsis and sinusitis may also cause pimples.
Hereditary factors also play a role in the cause of pimples. There are certain hormones that usually develop genetically. Thus, pimples often run in families hereditarily.
Even environmental factors contribute to the cause of pimples. The factors such as over exposure to sun or ultraviolet rays, dirt, pollution and very high dampness make the tiny pores of the skin to obstruct and allow the pimples to grow.
Regular diet also contributes to the cause of pimples. The diet containing oily, spicy, fatty substances, milk products, pastry, chocolates, sugar, and nuts makes the sebaceous glands to produce more sebum, causing more pimples.
Direct intake of bromine and iodine salts or the medicines containing these substances also relate to the cause of pimples.
Stress is also a factor for the cause of pimples. The physical as well as mental stress makes the body to release hormones and chemicals, which produce toxins that cause pimples [Stress Reduction].
Excess sweating is also a cause of pimples. The tiny pores will be obstructed from excess sweat, which cannot evaporate. Even, some greasy cosmetics observe into the skin and clog the pores and cause pimples.
