A lot of people usually tend to wonder about what may be the cause of acne that keeps breaking out on their face and skin in general. There are various reasons about what is responsible for this skin disorder. Some of these claims are usually unsubstantiated and most times such claims stem from the imagination of an uninformed person. Quite a number people still do not understand the basics of acne, most of them feel it is caused by some foods they eat or harsh weather and environmental conditions. Some of the causes of this disorder are reviewed below -:

Hyperactive Skin Sebaceous Glands-: sebaceous glands are found in the skin and are responsible for secreting sebum which is a fluid or oil that lubricates the skin surface. When these glands become overactive, some of the unused secreted oil that remains in the pore ends up blocking the pore. This leads to accumulation of bacteria in the pore, subsequently leading to inflammation and swellings. Some of the characteristics of the sebum from hyperactive glands also contain substances that may have a way of creating a conducive environment for acne causing bacteria to thrive.

Excessive Shedding of Skin Cells -: the skin layer known as the epidermis is always shedding off old skin cells to replace them with new skin cells. The skin of individuals who have acnes very often usually produces more dead skin cells than is normal. This leads to blockade of the skin pore by the dead cells that are constantly being produced. One the pore is blocked with dead cells, the sebum or oil secreted from the sebaceous glands find it difficult to get to the skin surface where it is needed for lubrication. The mixture of dead skin cells and sebum creates a good medium for bacteria to grow well. This makes bacteria to grow in the pores, and it results in swellings around the pore. When these swellings are exposed to the air they become black. This is what is often referred to as black heads.

High Concentration of Bacteria -: there is a class of bacteria known as propionibacteria acnes. It is often times found on most skins and it is known for causing acne especially when it is in very high quantities. These organisms are usually in considerably high amounts in pores of dead sebaceous glands. Oxygen concentrations in the blocked pores are usually very low leading to an anaerobic environment. This makes the bacteria population to thrive and grow the more. Oil from sebaceous glands trapped in the pore is then digested by the bacteria to produce a fatty acid waste. The fatty acid has an irritation effect on the skin pore lining causing redness and inflammation of the skin. This often leads to acne when it is not cared for properly.  The presence of bacteria should not be considered as lack of hygiene or an automatic cause of acne. Care should however, be taken to use good antibacterial soaps that have good cleansing qualities.
