What is Tinea Versicolor?
Tinea versicolor (also called Pityriasis Versicolor) is a yeast infection of the skin. This common medical dermatology condition frequently occurs in adolescents and young adults. It is caused by the fungus Malassezia, a type of yeast that can naturally be found on human skin. Usually, these microscopic organisms are not harmful, and in fact, protect you from infections and other pathogens that might cause diseases.
However, sometimes this yeast can grow out of control and can interfere with the natural pigmentation of the skin. When this happens, the skin develops discolored patches. These patches may be lighter or darker than the surrounding skin and commonly found on the upper part of the body (trunk and shoulders). This condition is not contagious nor painful at all, but it can cause some anxiety and depression to those that have it.
What Causes Tinea Versicolor?
Tinea Versicolor appears when the Malassezia rapidly overgrows on the skin. This phenomenon is yet to be explained, but some factors are known to promote the growth of this yeast on the skin. The following factors may trigger its growth:
- Oily skin
- Hot, humid weather
- Excessive sweating
- Hormonal changes
- A weakened immune system
Tinea Versicolor can occur to anyone, but in most cases, it appears more in teens and young adults.
Discolored patches on the skin are the most common symptom of Tinea versicolor. These patches are usually found at the upper body part, specifically on the arms, chest, neck, or back. These may be:
- White, pink, red, brown
- Lighter (more common) or darker than the skin surrounding them
- Dry, mild-itching, and scaling
- Unusual tanned spots
These spots are prone to disappear in cooler weather and might get worse when the humid, hot weather comes back.
Treatment for Tinea Versicolor
Tinea Versicolor, if not severe, can be treated with over-the-counter creams, lotions, or shampoos that are applied on the skin. In more severe cases, a visit to your dermatologist may be in order to have it professionally diagnosed and treated. Your type of treatment is dependent on the size, locations, and thickness of the infected area in your skin.
