What is Beach Fungus?
Beach fungus has nothing to do with the beach, but it is a fungal infection which may take some time to treat.
Beach fungus (pityriasis versicolor) is a harmless skin disease caused by an overgrowth of fungus called "Malassezia furfur" which may also be found on normal skin. Beach fungus sits on the upper body, arms, and neck and is uncommon on other parts of the body. It is more common in young people.
While not usually irritating or uncomfortable, it can cause the appearance of multiple tan, brown, salmon, or white scaling patches. In fair skinned people the condition is often diagnosed in summer months because the patches, which do not tan, become more obvious against tanned skin.
