What type of infection does tinea versicolor describe?

Tinea versicolor is indeed classified as a fungal yeast infection. It is caused by an overgrowth of a type of yeast called Malassezia that is normally found on the skin. When conditions are favorable, such as warm and humid environments, this yeast can proliferate and lead to the disruption of normal skin pigmentation. As a result, it causes lighter or darker patches on the skin, which may be more noticeable after sun exposure.

This condition is not caused by bacteria, viruses, or parasites, which are the causes of the other types of infections listed. Understanding that tinea versicolor is linked to a fungal organism helps clarify why proper antifungal treatments are required to effectively manage and resolve the condition.
