What it is
Pityriasis versicolor is an infection caused by a yeast-like fungus. This fungus is normally present on everyone’s skin surface in small numbers, and why only some people get the infection and others do not is not properly understood. It thrives in oily areas such as the neck, upper chest and back.
It commonly occurs in young adults. It causes both light and dark coloured patches with superficial fine scales, and the common sites are the upper chest, neck and back. It usually produces few symptoms. The infection can increase in summer, when the temperature and humidity are high. It does not spread from one person to another.
How we treat it
A dermatologist can easily recognise pityriasis versicolor. If necessary, a simple examination of the fine scales scraped from the skin confirms the diagnosis.
It is treated with applied and oral medicines. Remember to use the medicines for the full duration prescribed. The fungus usually responds to treatment, but it can take weeks to months for the skin to regain its normal colour, and the infection sometimes comes back.
