Skin Pore Blockage can cause acne.
One cause of acne is the blockage of skin oil secretions (sebum) that normally pass out of the skin through the hair follicles and then through the skin pores together with dead skin cells.
The clogged skin pore is one of the primary cause of acne, this is when the pore of the skin is clogged with dried sebum, dead skin cells and bacteria.
There are two types of blockage that is the cause of acne;
- Black Head (open comedone)- this is a cause of acne as black head develops as the dried sebum, dead skin cells and bacteria partially blocks the pore of the skin.
- White Head (closed comedone)- this is a cause of acne as white heads develop when the dried sebum, dead skin cells and bacteria completely blocks the pore of the skin.
In both instances, the blockage of the skin pore promotes the growth of bacteria propionibacterium acne which is normally present in the hair follicles and a cause of acne. When this happens the bacterial growth breaks down the sebum creating a substance irritating the skin. The resulting irritation inflames the skin resulting to skin eruptions called acne pimples. When irritation worsens, an abscess will form causing skin rupture, resulting to more inflammation.
Cosmetic use can also be the cause of acne. Cosmetics blocks the skin pores preventing the flow of oils and dead skin cells from the skin. This becomes the cause of acne.
Hormones can cause of acne
Increase in hormone levels is also considered as a cause of acne. Hormone imbalance aggravate the development of acne. That is why most teenagers suffer more from acne. But as the hormone level stabilizes by mid 20's acne usually disappears. Other conditions that involves hormonal changes such as menstrual periods and during pregnancies may also be the cause of acne. The taking of oral contraceptives and menopausal hormone replacement therapy may also be a cause of acne.
Drugs can also be a cause of acne
Certain drugs such as corticosteroids and anabolic steroids can also be a cause of acne pimples. These drugs stimulate the sebaceous glands secreting more oil or sebum. When these oil or sebum are blocked this may be the cause of acne.
Others causes of acne
Other cause of acne maybe exposure to sunlight, stress and other skin irritants that continuously comes in contact with the skin.
