Zits are a common term used to define the presence of spots and pimples on your skin surface. A pimple is nothing but a small pustule or a papule that appears on the skin surface. Zits are commonly called as pimples or spots. These are small skin lesions that develop when the sebaceous glands on the skin surface becomes clogged up leading to swelling and red lesions that are filled with pus.
Pimple appearance is primarily concerned with oil production, dead skin cells and clogged pores. Sebaceous glands become overactive due to the hormone dysregulation. Hormone dysregulation occurs generally around the time of menses and that is the time when acne starts appearing.
Parts affected with Acne or Zits
The most common parts that are affected with zits include: face, back, shoulders and chest. The pimples appear due to the proliferation of sebaceous glands. Generally people think pimples and acne are same but, pimples are a sign of acne especially when breakout occurs.
Causes of Pimples/Zits
The sebaceous glands are responsible for producing sebum. The dead skin cells are generally left behind and get stuck together by the sticky sebum resulting in causing blockage in the pores. Pore blockage usually occurs during puberty because the sebaceous glands produce more sebum at the time of puberty.
Sebum and dead skin cells together accumulate and block your pores and increase the growth of undesirable bacterium called Propionibacterium acne. Propionibacterium acne is a slow growing bacterium that is linked to acne on your skin surface.
Propionibacterium acne is normally present on your skin. When the conditions are favorable these organisms reproduce more rapidly and can create problems. The bacterium produces certain substances that cause an immune response resulting in skin inflammation and spots.
Pimples and zits are also associated with yeast infections. There are certain yeasts called Malassezia that can grow on your skin, forehead and chest. Yeast usually does not inhabit the same pores as Propionibacterium acne. Male hormone called testosterone is mainly responsible for producing excess sebum thus, increases the risk of appearance of clogged pores.
