Nearly everybody suffers from acne, so at some point in time everyone asks the common question “what causes acne?”  The answer to what causes acne is really dependent on a variety of factors.  There is no single source or cause that is cited for acne outbreaks, this is because researchers are finding that there are multiple causes for the baneful, irritating, embarrassing skin condition.

So what causes acne to erupt?  Further, why are there some individuals that seem more likely to develop the skin condition?  In truth, no matter how well you tend to your skin and no matter how committed you are to your hygienic practices, you can still wind up with undesirable acne eruptions.  Even worse, these eruptions can occur anywhere on your body.

While there are many causes of acne ,there are three main reasons why the condition occurs.  Acne outbreaks are commonly caused by things like sebaceous glands that are overactive, when you shed skin cells abnormally, or you could get acne because you have bacteria in or on your skin.

Skin Shedding Abnormalities and Their Role in Acne Development

The uppermost layer of your skin is identified as the epidermis.  This upper layer is continuously renewed by the shedding of skin cells that have died that are replaced with new, living tissue.  The process of shedding dead skin cells is further identified as desquamation; the dead cells will eventually fall off the epidermis as they are freed from the outer layer of your epidermis or the stratum corneum.  New cells grow in and take the place of the cells that fall away from the epidermis.  In some individuals, there are far too many skin cells produced resulting in the eventual presence of excessive dead skin cells.  When this happens, the cells clog the pores and follicles in the skin, resulting in the presence of unsightly acne eruptions.

Also within the uppermost layer of the epidermis, there are lamellar granules.  These granules naturally generate special digesting enzymes that consume the substance responsible for holding skin cells together.  When these granules fail to produce enough enzymes or when the enzymes do not do their job effectively, the result is the accumulation of more dead skin cells on the surface of the skin.  As the cells accumulate they form whiteheads and blackheads.

Sebaceous Glands and Their Role in Acne Development

So, how do sebaceous glands play a role in the formation of acne? Sebaceous glands are within the skin; they produce a special oil identified as sebum.  This sebum is needed to keep the skin’s surface flexible, supple, and lubricated.  However, when there is too much sebum, this product will eventually clog pores and hair follicles.  Sometimes the sebaceous glands become overactive and produce far more sebum than you actually need.  The sebum gets into follicles and pores, and clogs them.  This produces comedones or whiteheads and blackheads.  It can also cause small pimples, large pimples, and rash-like conditions.

Bacteria and Acne Formations

Everyone has some kind of bacteria on their skin, some good, and some bad.  Bad bacteria can result in acne formations.  The presence of bacteria is particularly prominent in what causes acne with inflammatory characteristics. In fact, bacteria is the common cause for Propionibacteria Acne conditions; this bacteria lives inside hair follicles and is oftentimes harmless, but it can quickly grow in an out of control manner resulting in clogged pours.  If a person has excessive sebum, this contributes to establishing an environment that allows the Propionibacteria to thrive.
