Comedones - Whiteheads, Blackheads, And What Makes Them Worse
By: Rebecca Prescott
Comedones are tiny bumps that affect the skin, making it rough to the touch, and these bumps can be dark, white or skin colored.
Most people know comedones by their more commonly used names - blackheads and whiteheads. These comedones are found at
the opening of the pores on the skin, and on those prone to acne are usually found around the chin and forehead areas. The
pigmentation of open comedones causes them to be dark, thus they are referred to as blackheads. However, those that are closed,
and where the follicle is totally blocked, are referred to as whiteheads.
Comedones are a primary sign of acne. With the open comedone, or blackhead, excess oils collect in the duct of the sebaceous
gland and the pigmentation makes them appear as black bumps on the surface of the skin. With a closed comedone, or whitehead,
the trapped sebum remains underneath the skin, causing a bumpy effect but no actual coloring is visible.
These comedones can vary in size - for instance, comedones that are larger than around two or three millimetres in diameter are
known as macrocomedones. Acne is not a condition that is exclusive to teenagers, as many people assume, and therefore both
comedones and acne can affect a person at any age, such as during pregnancy or during a highly emotional period.
What can aggravate comedones?
There are a number of factors that can aggravate and exacerbate comedones, and these include:
* Injuries that result in rupture of the follicle, such as abrasive facial washes or pimple squeezing
* Over hydration or over moisturization of the skin
* Excessive hormonal activity
* Free fatty acids caused by bacteria
* Various chemicals, such as those found in dye and some cosmetics
* Emotional factors
